    Respiratory patterns and turn-taking in spontaneous Estonian: Inhalation amplitude in multiparty conversations2015Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    This thesis explores the relationship between inhalation amplitude and turn-taking in spontaneous multiparty conversations held in Estonian. Respiratory activity is recorded with Respiratory Inductance Plethysmography. The main focus is on how inhalation amplitude varies between the inhalations produced directly before turn onset compared to the following inhalations within the same speaking turn. The results indicate a significant difference in amplitude, realised mainly by an increase in inhalation end lung volume values. One of the possible functions of this pattern is to signal an intention of taking the conversational turn. Another could be a phrasing or grouping function connected to lower inhalation amplitudes within turns.

    Backchannels and breathing2014Inngår i: Proceedings from FONETIK 2014: Stockholm, June 9-11, 2014 / [ed] Mattias Heldner, Stockholm: Department of Linguistics, Stockholm University , 2014, 47-52 s.Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    The present study investigated the timing of backchannel onsets within speaker’s own and dialogue partner’s breathing cycle in two spontaneous conversations in Estonian. Results indicate that backchannels are mainly produced near the beginning, but also in the second half of the speaker’s exhalation phase. A similar tendency was observed in short non-backchannel utterances, indicating that timing of backchannels might be determined by their duration rather than their pragmatic function. By contrast, longer non-backchannel utterances were initiated almost exclusively right at the beginning of the exhalation. As expected, backchannels in the conversation partner’s breathing cycle occurred predominantly towards the end of the exhalation or at the beginning of the inhalation.

    Inhalation amplitude and turn-taking in spontaneous Estonian conversations2015Inngår i: Proceedings from Fonetik 2015 Lund, June 8-10, 2015 / [ed] Malin Svensson Lundmark, Gilbert Ambrazaitis, Joost van de Weijer, Lund: Lund University , 2015, 1-5 s.Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    This study explores the relationship between inhalation amplitude and turn management in four approximately 20 minute long spontaneous multiparty conversations in Estonian. The main focus of interest is whether inhalation amplitude is greater before turn onset than in the following inhalations within the same speaking turn. The results show that inhalations directly before turn onset are greater in amplitude than those later in the turn. The difference seems to be realized by ending the inhalation at a greater lung volume value, whereas the initial lung volume before inhalation onset remains roughly the same across a single turn. The findings suggest that the increased inhalation amplitude could function as a cue for claiming the conversational floor.

    Effects of a film-based parental intervention on vocabulary development in toddlers aged 18-21 months2011Inngår i: Proceedings from Fonetik 2011: Speech, Music and Hearing; Quarterly Progress and Status Report, Stockholm, 2011, 105-108 s.Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    SPRINT is a language intervention project aimed to study the outcome of a parental home training program on children’s language development and future reading and writing skills. This study, which derives data from the SPRINT project, intended to examine the possible effects of a parental-based film intervention. It was conducted on toddlers aged 18-21 months from the Stockholm area with at least one parent who has Swedish as a first language. Parents of 78 children participated in the study and filled in 3 SECDI-w&s questionnaires rating their children's productive vocabulary. Children were randomized to either the intervention or the control group. Results indicated that the interventiongroup demonstrated significantly higher scores over time, F (2,78) = 5,192, p < .007. In the light of previous research it is concluded that this intervention contributes to an increase in productive vocabulary. However, the scores of the intervention group did not exceed the average range for Swedish children in the same age span. Furthermore the possible impact of parental education and thepresence of siblings on productive vocabulary was discussed.

    Productive vocabulary size development in children aged 18-24 months - gender differences2011Inngår i: Proceedings from Fonetik 2011: Speech, Music and Hearing; Quarterly Progress and Status Report, Stockholm, 2011, 109-112 s.Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    Several studies have shown slight differences in language skills between genders, favouring females. In order to investigate gender differences in speech production for Swedish children, the productive vocabulary size of 295 children, aged 18-24 months, was measured by the validated instrument SECDI-2. The size of the productive vocabulary was found to grow rapidly during this age. Significant gender differences were found at 21 and 24 months, but not at 18 months. The girls’ mean scores were higher.

    Voices after midnight: How a night out affects voice quality2014Inngår i: Proceedings from FONETIK 2014: Stockholm, June 9-11, 2014 / [ed] Mattias Heldner, Stockholm: Department of Linguistics, Stockholm University , 2014, 1-4 s.Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    This study aimed to investigate how different parameters of the voice (jitter, shimmer, LTAS and mean pitch) are affected by a late night out. Three recordings were made: one early evening before the night out, one after midnight, and one on the next day. Each recording consisted of a one minute reading and prolonged vowels. Five students took part in the experiment. Results varied among the participants, but some patterns were noticeable in all parameters. A trend towards increased mean pitch during the second recording was observed among four of the subjects. Somewhat unexpectedly, jitter and shimmer decreased between the first and second recordings and increased in the third one. Due to the lack of ethical testing, only a small number of participants were included. A larger sample is suggested for future research in order to generalize results.

    Anticipatory Looking in Infants and Adults2011Inngår i: Proceedings of EyeTrackBehavior 2011, 2011Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    Infant language acquisition research faces the challenge of dealing with subjects who are unable to provide spoken answers to research questions. To obtain comprehensible data from such subjects eye tracking is a suitable research tool, as the infants’ gaze can be interpreted as behavioural responses. The purpose of the current study was to investigate the amount of training necessary for participants to learn an audio-visual contingency and present anticipatory looking behaviour in response to an auditory stimulus. Infants (n=22) and adults (n=16) were presented with training sequences, every fourth of which was followed by a test sequence. Training sequences contained implicit audio-visual contingencies consisting of a syllable (/da/ or /ga/) followed by an image appearing on the left/right side of the screen. Test sequences were identical to training sequences except that no image appeared. The latency in time to first fixation towards the non-target area during test sequences was used as a measurement of whether the participants had grasped the contingency. Infants were found to present anticipatory looking behaviour after 24 training trials. Adults were found to present anticipatory looking behaviour after 28-36 training trials. In future research a more interactive experiment design will be employed in order to individualise the amount of training, which will increase the time span available for testing.

    Preceding non-linguistic stimuli affect categorisation of Swedish plosives2012Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Speech perception is highly context-dependent. Sounds preceding speech stimuli affect how listeners categorise the stimuli, regardless of whether the context consists of speech or non-speech. This effect is acoustically contrastive; a preceding context with high-frequency acoustic energy tends to skew categorisation towards speech sounds possessing lower-frequency acoustic energy and vice versa (Mann, 1980; Holt, Lotto, Kluender, 2000; Holt, 2005). Partially replicating Holt's study from 2005, the present study investigates the effect of non-linguistic contexts in different frequency bands on speech categorisation. Adult participants (n=15) were exposed to Swedish syllables from a speech continuum ranging from /da/ to /ga/ varying in the onset frequencies of the second and third formants in equal steps. Contexts preceding the speech stimuli consisted of sequences of sine tones distributed in different frequency bands: high, mid and low. Participants were asked to categorise the syllables as /da/ or /ga/. As hypothesised, high frequency contexts shift the category boundary towards /da/, while lower frequency contexts shift the boundary towards /ga/, compared to the mid frequency context.

    Training in Anticipatory Looking Experiments with Adult Participants2011Inngår i: Proceedings of the 17th International Congress of Phonetic Sciences / [ed] Wai-Sum Lee & Eric Zee, 2011, 316-319 s.Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The amount of training necessary to trigger anticipatory looking was investigated in adults (n=16) using a simple testing paradigm, in order to create a baseline for studies on infants’ language acquisition. Participants were presented with training containing implicit associations between two syllables (/da/ and /ga/) and visual events displayed on different areas on the screen. The training series were periodically interrupted by test trials where a syllable was presented but no visual event was displayed. Significantly altered looking behaviour, as measured by participants’ first gaze fixation latency towards the Non-target area (where the visual event should not be expected), was found after 28-36 training trials.

    A Study of Simultaneous-masking and Pulsation-threshold Patterns of a Steady-state Synthetic Vowel: A Preliminary Report2006Inngår i: Working Papers 52 (2006): Proceedings from FONETIK 2006, Lund, June 7-9, 2006 / [ed] Ambrazaitis, G. & Schötz, S., Lund: Lund University, Centre for Languages and Literature , 2006, 13-16 s.Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This study will be a remake in part of Tyler & Lindblom "Preliminary study of simultaneous masking and pulsation-threshold patterns of vowels" (1982), with the use of today's technology. A steady-state vowel as masker and pure tones as signals will be presented using simultaneous-masking (SM) and pulsation-threshold (PT) procedures in an adjustment method to collect the vowel masking pattern. Vowel intensity is changed in three steps of 15 dB. For SM, each 15 dB change is expected to result in about a 10-13-dB change in signal thresholds. For PT, the change in signal thresholds with vowel intensity is expected to be about 3-4 dB. These results would correspond with the results from the Tyler & Lindblom study. Depending on technology outcome, further experiments can be made, involving representations of dynamic stimuli like CV-transitions and diphthongs.

    Effekten av fonologisk träning enligt Bornholmsmodellen på elevers språkliga medvetenhet i årskurs 12001Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Denna rapport är en del av en longitudinell studie av psykolingvistisk ålder och språklig medvetenhet hos elever i årskurs 1 på två olika skolor i Vallentuna kommun. I studien har material från de tre senaste projektåren bearbetats. Syftet med undersökningen var att undersöka huruvida fonologisk träning enligt den s.k. Bornholmsmodellen under elevernas tid i 6-årsklass återspeglar sig i ökad språklig medvetenhet och högre psykolingvistisk ålder i årskurs 1. Vidare undersöktes om den fonologiska träningen kan ha påverkat barnens arbetsminne. Två typer av test användes: UMESOL för kartläggning av fonologisk medvetenhet och ITPA, ett standardiserat test av psykolingvistiska färdigheter. Resultaten visar att det finns ett klart samband mellan fonologisk träning enligt Bornholmsmodellen i förskolan och elevernas språkliga medvetenhet i grundskolan. Vidare visar resultaten att även om minnesträningen i Bornholmsmodellen inte direkt påverkat resultaten vid ITPA, så finns det ett starkt samband mellan minnestestet i ITPA och elevernas prestation vid UMESOL.

    Effekten av fonologisk träning enligt Bornholmsmodellen på elevers tidiga läs- och skrivinlärning i årskurser 1 och 22002Independent thesis Advanced level (degree of Master (One Year)), 10 poäng / 15 hpOppgave
    Abstract [sv]

    I en longitudinell studie har elever i årskurs 1 och 2 på två olika skolor i Vallentuna kommun undersökts under tre på varandra följande projektår. Huvudsyftet med denna studie var att undersöka huruvida träning i fonologisk medvetenhet enligt den s.k. Bornholmsmodellen under elevernas tid i sexårsklass påverkar deras läs- och skrivinlärning. Tre typer av test användes, under årskurs 1 administrerades UMESOL för kartläggning av fonologisk medvetenhet och ITPA, för kartläggning av psykolingvistiska färdigheter. Under årskurs 2 kartlades elevernas läs- och skrivutveckling med UMESOL, ”läsning och skrivning”. I kontrast med tidigare forskningsresultat som pekade på en fördelaktig användning av Bornholmsmodellen under elevernas förskoleklassår, visade resultaten i denna studie inte på entydiga långsiktiga effekter för de elever som tränats fonologiskt enligt Bornholmsmodellen. Istället verkade den avgörande faktorn för elevernas läs- och skrivutveckling vara skoltillhörighet och pedagogisk ledning under dessa första skolår.

    Lingvistiska och interaktiva aspekter på barn-vuxen kommunikation ur ett patologiskt perspektiv2005Inngår i: Konferensrapport från Tionde Nordiska Barnspråkssymposiet, Gävle 2005, Gävle: Högskolan i Gävle , 2005, 32-38 s.Konferansepaper (Fagfellevurdert)
    Abstract [sv]

    Som en del av pågående forskning vid fonetiklaboratoriet, SU, utförs månatligen inspelningar med syfte att studera interaktionen i en mor-barndyad, där barnet har ett medfött produktions- och perceptionshandikapp. En pojke, född med Hemifacial Mikrosomia, vilket innebär partiellt försämrad hörsel, undersöks under åldrarna 8-30 månader. Syndromet inbegriper bl a avsaknad av vänster ytteröra, kind- och okben. Barnet har sondmatats via näsan upp till ca 8 månaders ålder. Studien är inriktad på pojkens språkliga och kommunikativa utveckling och på föräldrarnas samspel med honom. För att undersöka hur representationer av barnets tidiga ord kan utvecklas hos ett handikappat barn görs dels analyser av barnets vokalisationer, joller och tal och dels analyser av moderns lingvistiska struktur, timing och turtagning, repetitioner och strategi att anpassa sig till barnets uppmärksamhetsfokus. Audio- och videoinspelningar används för att samla in data på förälder-barn interaktionen och barnets vokalisationer. Eyetracking mäter barnets ögonrörelser vid presentation av audiovisuella stimuli. SECDI formulär används regelbundet för att undersöka utvecklingen av barnets lexikala produktion. Preliminära analyser tyder på generella ökade interaktiva åtgärder från föräldrarna. För att underlätta kommunikation och språklig utveckling har föräldrarna bl a introducerat tecken som stöd (TSS).

    Abstract [en]

    The perceptual significance of enhancing amplitude contrasts at the onset of formant transitions in CV-syllables and of reducing the “speaking” tempo was studied with a group of normally developing school children. Natural and synthetic speech stimuli were used in the perception experiments. A total of 83 children, second and third graders, were tested on their ability to discriminate between CV syllables presented in pairs. The results indicate that the children’s discrimination performance resisted acoustic manipulations of both the natural and synthetic stimuli. Neither spectral nor timing manipulations rendered significant differencesin discrimination results.

    Influence of pre-school phonological training on early reading and writing abilities2003Inngår i: 15th International Congress of Phonetic Sciences (ICPhS) 2003, 2003, 2846-2848 s.Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This paper reports a study of the possible impact of pre-school phonological training on first and second graders' reading and writing abilities. Two public schools in the Stockholm metropolitan area were selected. The children were divided in two groups, depending on whether or not they had participated in a phonological training program in their last pre-school year. The children's linguistic and literacy development was followed during their first two school years. Psycholinguistic profiles (ITPA) were obtained for all the first grade children, along with an assessment of their phonological awareness. In the second grade, the children were reassessed to map their reading and writing abilities. Although the results suggested an initial advantage in general linguistic awareness for the children enrolled in the phonological training program, that advantage seems to be quickly overshadowed by social and personal factors such as continuity in the pedagogical leadership and attended school.

    On Linguistic and Interactive Aspects of Infant-Adult Communication in a Pathological Perspective2005Inngår i: Proceedings, FONETIK 2005 / [ed] Eriksson, A & Lindh, J., Göteborg: Göteborgs universitet, Institutionen för lingvistik , 2005, 55-58 s.Konferansepaper (Fagfellevurdert)
    Abstract [en]

    This is a preliminary report of a study of some linguistic and interactive aspects available in an adult-child dyad where the child is partially hearing impaired, during the ages 8 - 20 months. The investigation involves a male child, born with Hemifacial Microsomia. Audio and video recordings are used to collect data on child vocalization and parent-child interaction. Eye-tracking is used to measure eye movements when presented with audio-visual stimuli. SECDI forms are applied to observe the development of the child's lexical production. Preliminary analyses indicate increased overall parental interactive behaviour. As babbling is somewhat delayed due to physical limitations, signed supported Swedish is used to facilitate communication and language development. Further collection and analysis of data is in progress in search of valuable information of the linguistic development from a pathological perspective of language acquisition.

    Effekten av talarformanten och F0's styrka på otränade röstbedömare2013Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Tal och röst styrs av komplicerade processer, där vitt skilda funktioner används i dess produktion och perception. Hur tal och röst uppfattas skiljer sig på flera sätt från den objektiva mätbara akustiska talsignalen. Grundtonens, F0’s, styrka och det man kallar talarformanten är två parametrar som påverkar hur rösten låter. Studien hade som syfte att undersöka om grundtonens styrka och med eller utan talarformant påverkar vilka stimuli otränade röstbedömare tycker bäst om. För att undersöka detta skapades ett syntetiskt /a/ efter formantfrekvenser för svenska vokaler (Fant, 1959), som varierades med utan eller med talarformant och med sju olika grundtonsstyrkor, totalt fjorton stimuli. Tolv kvinnor och åtta män, fick lyssna på /a/:na och skatta dem från det /a/ som de gillade mest till det /a/ som de gillade minst. Studiens frågeställningar bekräftades, variationer av grundtonens styrka och med eller utan talarformant påverkade vilka stimuli otränade röstbedömare föredrog, och män och kvinnor föredrog olika stimuli. De två /a/:na med svagast och det /a/ med starkast grundton, gillades minst av hela gruppen. De fyra /a/:na däremellan tyckte informanterna om ungefär lika mycket. Studerade man var för sig vad män och kvinnor skattade blev resultatet annorlunda. Kvinnor föredrog stimuli med talarformant mer än de utan talarformant, medan män föredrog stimuli med stark grundton. Ytterligare studier kunde vara intressanta att göra, för att undersöka om stimulus egenskaper med avseende på talarformant och grundtonsstyrka har någon effekt på hur tal uppfattas och tolkas.

    Perception of lexical tone across languages: Evidence for a linguisticmode of processing1996Inngår i: Proceedings of the 4th InternationalConference on Spoken Language Processing / [ed] T. Bunnell & W. Isardi, 1996, 2514-2517 s.Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Pairs of Thai tones were presented for perceptual discrimination inthree linguistic contexts (normal speech, low-pass filtered speech,and as musical (violin) sounds) to tonal language speakers, Thaiand Cantonese, and non-tonal (English) language speakers.English speakers discriminated the tonal contrasts significantlybetter in the musical context than in filtered speech, and in filteredspeech better than in full speech. On the other hand, both Thaiand Cantonese speakers perceived the tonal contrasts equally wellin all three contexts. Thus developmental absence of exposure tolexical tone results in a linguistic mode of processing whichinvolves the attenuation of a basic psychoacoustic ability, pitchdiscrimination.

    Universality and language-specific experience in the perception of lexical tone and pitch2015Inngår i: Applied Psycholinguistics, ISSN 0142-7164, E-ISSN 1469-1817, Vol. 36, nr 6, 1459-1491 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Two experiments focus on Thai tone perception by native speakers of tone languages (Thai, Cantonese, and Mandarin), a pitch–accent (Swedish), and a nontonal (English) language. In Experiment 1, there was better auditory-only and auditory–visual discrimination by tone and pitch–accent language speakers than by nontone language speakers. Conversely and counterintuitively, there was better visual-only discrimination by nontone language speakers than tone and pitch–accent language speakers. Nevertheless, visual augmentation of auditory tone perception in noise was evident for all five language groups. In Experiment 2, involving discrimination in three fundamental frequency equivalent auditory contexts, tone and pitch–accent language participants showed equivalent discrimination for normal Thai speech, filtered speech, and violin sounds. In contrast, nontone language listeners had significantly better discrimination for violin sounds than filtered speech and in turn speech. Together the results show that tone perception is determined by both auditory and visual information, by acoustic and linguistic contexts, and by universal and experiential factors.

    En undersökning av sambandet mellan språklig och motorisk utveckling hos 8-16 månader gamla barn: En analys av föräldrars skattningar i testinstrumentet Swedish Early Communicative Development Inventory (SECDI)2007Rapport (Annet vitenskapelig)
    Abstract [sv]

    Föräldrar till barn i åldrarna 8-16 månader har i samband med en forskningsstudie vid Stockholms universitet skattat sina barns färdigheter och förmågor med hjälp av formuläret SECDI. För undersökning av motorisk och språkliga utveckling hos barn valdes barn i åldrarna 8, 10, 12, 14 och 16 månader ut. Barnens skattade språkliga förmågor jämfördes med deras skattade motoriska förmågor. Syftet med detta specialarbete är att utifrån föräldrarnas skattningar av sina barns färdigheter undersöka om det finns ett samband mellan motorisk och språklig färdighet hos små barn. Undersökningens resultat påvisar ett sådant samband. Summan av antal förstådda respektive sagda ord korrelerade starkt med summan av antal gester. En bakomliggande variabel tros vara barnens ålder vilket visar sig som en signifikant korrelation mellan barnens språkliga och motoriska utveckling samt ålder.

    Mapping articulatory parameters on formant patterns: From articulations to acoustics non-stop2010Independent thesis Advanced level (degree of Master (One Year)), 20 poäng / 30 hpOppgave
    Abstract [en]

    The traditional way of estimating the formant frequencies from articulatory data presupposes knowledge of how the vocal tract cross-sectional area varies for a given articulatory shape (Fant 1960/1970). Accordingly, in order to derive the formant pattern of a given articulation, the three-dimensional shape of the vocal tract (VT) needs to be known. In the past cross-sectional areas have typically been derived by means of ‘d-to-A rules’ that use the mid-sagittal cross-distance d at each point along the VT to produce a corresponding cross-sectional area A. X-ray and MRI data have been used to calibrate such rules (Heinz & Stevens 1964, Sundberg et al. 1987, Ericsdotter 2005). Although this procedure has produced many useful results it is time consuming and laborious. It is speaker-specific. It presupposes access to information on the three-dimensional shape of the VT, which is not experimentally readily accessible. Such observations raise the question whether sufficiently accurate alternative approaches can be developed. Is it possible to go straight from articulatory data to formant frequencies without having to construct a cross-sectional area function? If such methods could be developed it would have many uses both in phonetics and practical applications.

    This paper reports an attempt to map the time variations of selected articulatory parameters from X-ray profiles directly on the formant tracks using multiple regression analysis. Preliminary results for F1 indicate that multiple regression analysis can indeed be useful for making such predictions. The prospects of extending the present analyses to other formants are discussed.

    WILD 2015: Book of Abstracts2015Konferanseproceedings (Annet vitenskapelig)
    Abstract [en]

    WILD 2015 is the second Workshop on Infant Language Development, held June 10-12 2015 in Stockholm, Sweden. WILD 2015 was organized by Stockholm Babylab and the Department of Linguistics, Stockholm University. About 150 delegates met over three conference days, convening on infant speech perception, social factors of language acquisition, bilingual language development in infancy, early language comprehension and lexical development, neurodevelopmental aspects of language acquisition, methodological issues in infant language research, modeling infant language development, early speech production, and infant-directed speech. Keynote speakers were Alejandrina Cristia, Linda Polka, Ghislaine Dehaene-Lambertz, Angela D. Friederici and Paula Fikkert.

    Organizing this conference would of course not have been possible without our funding agencies Vetenskapsrådet and Riksbankens Jubiléumsfond. We would like to thank Francisco Lacerda, Head of the Department of Linguistics, and the Departmental Board for agreeing to host WILD this year. We would also like to thank the administrative staff for their help and support in this undertaking, especially Ann Lorentz-Baarman and Linda Habermann.

    From movements to sound Contributions to building the BB speech production system2006Rapport (Annet vitenskapelig)
    Abstract [en]

    In terms of anatomical geometry the infant Vocal Tract undergoes significant change during development. This research note reports an attempt to reconstruct an infant VT from adult data. Comparable landmarks were identified on the fixed structures of adult articulatory lateral profiles (obtained from X-ray images) and matching infant profiles (obtained from published data in the literature, Sobotta [Putz & Pabst 2001, and personal communication from author Prof. Dr. med. R. Pabst]. The x-coordinates of the infant landmarks could be accurately derived by a linear scaling of the adult data whereas the y-values required information on both the x- and the y-coordinates of the adult. These scaling rules were applied to about 400 adult articulatory profiles to derive a set of corresponding infant articulations. A Principal Components Analysis was performed on these shapes to compare the shapes of the infant and adult articulatory spaces. As expected from the scaling results the infant space is significantly compressed in relation to the adult space suggesting that the main articulatory degree of freedom for the child is jaw opening. This finding is in perfect agreement with published descriptions of the phonetics of early vocalizations.

    From articulatory to acoustic parameters non-stop: Phonetics in the fast lane2008Inngår i: Proceedings FONETIK 2008Artikkel i tidsskrift (Annet vitenskapelig)
    Abstract [en]

    This paper reports an attempt to map the time variations of selected articulatory parameters (from X-ray profiles) directly on the F1, F2 and F3 formant tracks using multiple regression analysis (MRA). The results indicate that MRA can indeed be useful for predicting formant frequencies. Since the results reported here are limited to preliminary observations of F1 only, further studies including F2 and F3 are needed to evaluate the method more definitively.

    Parent-child interaction: Relationship between pause duration and infant vocabulary at 18 months2011Inngår i: Proceedings from Fonetik 2011: Speech, Music and Hearing; Quarterly Progress and Status Report, Stockholm, 2011, 101-104 s.Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    Studies of child language development have shown that children from an early age are aware of turn-taking patterns in interaction. The aim of this study is to investigate if there is a relationship between turn-taking pauses in parent-child interaction and child vocabulary at 18 months of age. Analysis of pause duration is conducted on recordings from the SPRINT language intervention project and pause duration is found to correlate with child vocabulary size. Different possible reasons for this correlation are discussed.

    3rd party observer gaze as a continuous measure of dialogue flow2012Konferansepaper (Fagfellevurdert)
    Abstract [en]

    We present an attempt at using 3rd party observer gaze to get a measure of how appropriate each segment in a dialogue is for a speaker change. The method is a step away from the current dependency of speaker turns or talkspurts towards a more general view of speaker changes. We show that 3rd party observers do indeed largely look at the same thing (the speaker), and how this can be captured and utilized to provide insights into human communication. In addition, the results also suggest that there might be differences in the distribution of 3rd party observer gaze depending on how information-rich an utterance is.

    On the effect of the acoustic environment on the accuracy of perception of speaker orientation from auditory cues alone2012Inngår i: INTERSPEECH 2012: vol.2, Portland, USA: Curran Associates, Inc. , 2012, 1482-1485 s.Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The ability of people, and of machines, to determine the position of a sound source in a room is well studied. The related ability to determine the orientation of a directed sound source, on the other hand, is not, but the few studies there are show people to be surprisingly skilled at it. This has bearing for studies of face-to- face interaction and of embodied spoken dialogue systems, as sound source orientation of a speaker is connected to the head pose of the speaker, which is meaningful in a number of ways. The feature most often implicated for detection of sound source orientation is the inter-aural level difference - a feature which it is assumed is more easily exploited in anechoic chambers than in everyday surroundings. We expand here on our previous studies and compare detection of speaker orientation within and outside of the anechoic chamber. Our results show that listeners find the task easier, rather than harder, in everyday surroundings, which suggests that inter-aural level differences is not the only feature at play.

We describe in passing some preliminary findings that led us onto this line of investigation, and in detail a study in which we extend an experiment design intended to measure perception of gaze direction to test instead for perception of sound source orientation. The results corroborate those of previous studies, and further show that people are very good at performing this skill outside of studio conditions as well.

    Catching wind of multiparty conversation2014Inngår i: Proceedings of Multimodal Corpora: Combining applied and basic research targets (MMC 2014) / [ed] Jens Edlund, Dirk Heylen, Patrizia Paggio, Reykjavik, Iceland: European Language Resources Association , 2014, 35-36 s.Kapittel i bok, del av antologi (Annet vitenskapelig)
    Abstract [en]

    The paper describes the design of a novel multimodal corpus of spontaneous multiparty conversations in Swedish. The corpus is collected with the primary goal of investigating the role of breathing and its perceptual cues for interactive control of interaction. Physiological correlates of breathing are captured by means of respiratory belts, which measure changes in cross sectional area of the rib cage and the abdomen. Additionally, auditory and visual correlates of breathing are recorded in parallel to the actual conversations. The corpus allows studying respiratory mechanisms underlying organisation of spontaneous conversation, especially in connection with turn management. As such, it is a valuable resource both for fundamental research and speech techonology applications.

    Does production facilitate discrimination?: An infant mismatch negativity study2013Inngår i: Proceedings of Fonetik 2013: Studies in Language and Culture no. 21 / [ed] Robert Eklund, Linköping, 2013, 17-20 s.Konferansepaper (Fagfellevurdert)
    Abstract [en]

    MMN is an ERP component that reflects preattentive discrimination between a recurring standard sound and a deviating sound. MMN is frequently used in infant studies focused on speech development since its elicitation does not require the attention of the child. The general ability of infants to discriminate speech sounds is gradually specialized towards discrimination of phonetic contrasts in their mother tongue. The aim of the present study was to examine if an MMN response is elicited by naturally varying speech stimuli (/ ti/ and / ki/) and if this response is stronger for the speech sound that infants typically produce at this age (/ t/). An EEG experiment with an oddball paradigm was designed. Participants were 19 infants (9-mo). An MMN-like negative response to deviants compared to standards was found, however it was not statistically significant. No significant interaction effect was found for MMN and type of deviant stimulus. Variation in the standard stimuli may have contributed to the lack of effect. It is also possible that the infants already were equally competent in discriminating both speech sounds, which may account for the small difference between the deviant waveforms.

    Acoustic analysis of adults imitating infants: a cross-linguistic perspective2012Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The present study investigates adult imitations of infant vocalizations in a cross-linguistic perspective. Japanese-learning and Swedish-learning infants were recorded at ages 16-21 and 78-79 weeks. Vowel-like utterances (n=210) were selected from the recordings and presented to Japanese (n=3) and Swedish (n=3) adults. The adults were asked to imitate what they heard, simulating a spontaneous feedback situation between caregiver and infant. Formant data (F1 and F2) was extracted from all utterances and validated by comparing original and formant re-synthesized utterances. The data was normalized for fundamental frequency and time, and the accumulated spectral difference was calculated between each infant utterance and each imitation of that utterance. The mean spectral difference was calculated and compared, grouped by native language of infant and adult, as well as age of the infant. Preliminary results show smaller spectral difference in the imitations of older infants compared to imitations of the younger group, regardless of infant and adult native language. This may be explained by the increasing stability and more speech-like quality of infants' vocalizations as they grow older (and thus have been exposed to their native language for a longer period of time), making their utterances easier for adults to imitate.

    The beginnings of a database for historical sound change2008Inngår i: Papers from the 21st Swedish Phonetics Conference, 2008, 101-104 s.Konferansepaper (Annet vitenskapelig)
    Abstract [en]

    We report a preliminary version of a database from which examples of historical sound change can be retrieved and analyzed. To date, the database contains about 1,000 examples of regular sound changes from a variety of language families. As exemplified in the text, searches can be made based on IPA symbols, articulatory features, segmental or prosodic context, or type of change. The database is meant to provide an adequately large sample of areally and genetically balanced information on historical sound changes that tend to take place in the world’s languages. It is also meant as a research tool in the quest for diachronic explanations of genetic and areal biases in synchronic typology.

    Syllable prominence: An experimental study2015Inngår i: Lingue e linguaggio, ISSN 1720-9331, Vol. XIV, nr 1, 43-60 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    There are many studies of word stress (or lexical stress) in different languages. One problem if one wants to compare the acoustics of word stress in different languages is that the studies are often made in such a way that the results are not immediately comparable. One goal of the project described here is to develop a framework for analysing the acoustics of word stress that can be applied in the same way to any language. A second goal is to examine the perception of syllable prominence as a cue to lexical stress perception. The acoustic properties are obviously a factor to be considered, but we have reasons to believe, based on results from a previous experiment (Eriksson et al. 2002), that the native language of the listener may also influence perceived prominence and thus lexical stress perception. The languages included in the study so far are Brazilian Portuguese, English, Estonian, French, German, Italian and Swedish. At present only the Swedish material has been analysed using the complete set of recordings. In this paper I will therefore only give a full presentation of the Swedish result. Results based on subsets of the data from the other languages (usually 10 speakers) will be referred to as “preliminary results”. Some of these results have been presented in more detail in conference proceedings (see references).

    The Acoustics of Lexical Stress in Italian as a Function of Stress Level and Speaking Style2016Inngår i: Proceedings Interspeech 2016, International Speech Communication Association, 2016, 1059-1063 s.Konferansepaper (Fagfellevurdert)
    Abstract [en]

    The study is part of a series of studies, describing the acoustics of lexical stress in a way that should be applicable to any language. The present database of recordings includes Brazilian Portuguese, English, Estonian, German, French, Italian and Swedish. The acoustic parameters examined are F0-level, F0- variation, Duration, and Spectral Emphasis. Values for these parameters, computed for all vowels (a little over 24000 vowels for Italian), are the data upon which the analyses are based. All parameters are examined with respect to their correlation with Stress (primary, secondary, unstressed) and speaking Style (wordlist reading, phrase reading, spontaneous speech) and Sex of the speaker (female, male). For Italian Duration was found to be the dominant factor by a wide margin, in agreement with previous studies. Spectral Emphasis was the second most important factor. Spectral Emphasis has not been studied previously for Italian but intensity, a related parameter, has been shown to correlate with stress. F0-level was also significantly correlated but not to the same degree. Speaker Sex turned out as significant in many comparisons. The differences were, however, mainly a function of the degree to which a given parameter was used, not how it was used to signal lexical stress contrasts.
