    Comparative study of male and female whispered and phonated versions of the long vowels of Swedish1997In: Phonetica, ISSN 0031-8388, E-ISSN 1423-0321, Vol. 54, no 1, 1-21 p.Article in journal (Refereed)
    Abstract [en]

    Confusions in vowel quality and in speaker sex for whispered and phonated versions of the long vowels of Swedish have been analysed. The recognition rate was higher than that obtained in other studies, and this is attributed to the use of real words (letter names). The recognition of vowel quality was observed to interact with that of speaker sex in the whispered versions, but not in the phonated ones. The paper also reports on F0 and the frequency positions of the first three formants, and their dynamics, as well as on the overall spectral shape of the vowels. Intrinsic pitch and the observed upward shift of the lower formants in whispering as well as the spectral level differences agree largely with those found in other languages. Similarities and discrepancies with previous descriptions of the Swedish vowels are discussed.

    Perception of syllable prominence by listeners with and without competence in the tested language2002In: Proceedings of the Speech Prosody 2002 Conference, 2002, 275-278 p.Conference paper (Other academic)
    Abstract [sv]

    In an experiment reported previously, subjects rated perceived syllable prominence in a Swedish utterance produced by ten speakers at various levels of vocal effort. The analysis showed that about half of the variance could be accounted for by acoustic factors. Slightly more than half could be accounted for by linguistic factors. Here, we report two additional ex-periments. In the first, we attempted to eliminate the linguistic factors by repeating the Swedish listening experiment with English listeners who had no knowledge of Swedish. In the second, we investigated the prominence pattern Swedish sub-jects expect by presenting the utterance only in written form. The results from these subjects and from the Swedish listeners were very similar but for two of the syllables where the promi-nence pattern did not coincide with the expectations of the readers. Swedish and English listeners perceived the promi-nence of the syllables to be almost identical in most cases, but where there was a conflict between expected and produced prominence, the Swedish listeners appeared to be influenced by their expectations. There was also a difference in the weights the Swedish and English listeners attached to different acoustic cues in the listening experiments.

    Syllable prominence: A matter of vocal effort, phonetic distinctness and top-down processing2001In: Proceedings of EuroSpeech-2001, 2001, 399-402 p.Conference paper (Other academic)
    Abstract [en]

    In this experiment, subjects had to rate the "prominence" of each of the syllables of 20 versions of the same utterance produced by men, women and children at various levels of vocal effort. The ratings were correlated with measurements of the SPL of the fundamental, spectral emphasis, vowel duration, F0max and F0 rise from the previous syllable. Together with ratings of the perceived vocal effort at which the utterances had been produced, these measurements were used to obtain the possible contributions of vocal effort, prosodic distinctness, and vowel duration to the perceived prominence. Together, these accounted for half of the variance. This was compared with the possible contribution of the linguistic structure of the utterance, which accounted for slightly more of the variance. The predictions of a model based on this analysis came closer to the mean than the average subject.

    Perception of vocal effort and distance from the speaker on the basis of vowel utterances.2002In: Percept Psychophys, ISSN 0031-5117, Vol. 64, no 1, 131-9 p.Article in journal (Refereed)
    Abstract [en]

    The sound pressure level of vowels reflects several non-linguistic and linguistic factors: distance from the speaker, vocal effort, and vowel quality. Increased vocal effort also involves an emphasis of higher frequency components and increases in F0 and F1. This should allow listeners to distinguish it from decreased distance, which does not have these additional effects. It is shown that listeners succeed in doing so on the basis of single vowels if phonated, but not if whispered. The results agree with a theory according to which listeners demodulate speech signals and evaluate the properties of the carrier signal, which reflects most of the para- and extra-linguistic information, apart from those of its linguistic modulation. It is observed that listeners allow for between-vowel variation, but tend to substantially underestimate changes in both kinds of distance.

    Perception of back vowels: effects of varying F1 - F0 Bark distance.1996In: J Acoust Soc Am, ISSN 0001-4966, Vol. 99, no 4 Pt 1, 2350-7 p.Article in journal (Refereed)
    Abstract [en]

    In a study of vowel height perception using front vowels, Hoemeke and Diehl [J. Acoust. Soc. Am. 96, 661 - 674 (1994)] found that F1 - F0 distance was the best predictor of perceived vowel height for the phonological distinction [+/-high], while for two other vowel height distinctions F1 alone was the best predictor. Further, the [+/-high] identification function was defined by a sharp boundary located at 3 to 3.5 Bark F1-F0 distance. One hypothesis offered was that F1 - F0 distance had cue value for the [+/-high] distinction because of an underlying quantal region on the F1 - F0 distance dimension. However, the results are also predicted if it is supposed that F1 - F0 distance is a cue for vowel height only for pure height distinctions. The present study further tested these possibilities, using back vowels. The results allowed us to reject both as general explanations of vowel height perception. However, the results were consistent with a third possible explanation, namely, that phonetic quality is determined by the tonotopic distances between any adjacent spectral peaks (e.g., F3 - F2, F2 - F1, and F1 - F0), with greater perceptual weight accorded to smaller distances.

    Perception of quantity in Estonian2000In: Fonetik 2000, 2000, 85-88 p.Conference paper (Other academic)
    Abstract [en]

    An experiment is described in which the speech rate of a short preceding or following context was manipulated in addition to that of a vowel or a consonant that carried a quantity distinction. The results showed the durations of these segments and the speech rate of their left and right context to be crucial for quantity perception.

    Abstract [en]

    In the experiment reported here, the speech rate of a short preceding or following context was manipulated in addition to that of a V, C or VC-sequence that carried a quantity distinction. The results showed that the durations of the other segments within the same two-syllable rhythmic foot and the presence or absence of a third syllable contributed to quantity perception.

    Speaking rate and perceived quantity: an experiment with Italian listeners2006In: Fonetik 2006: Working Papers 52, 2006, 81-84 p.Conference paper (Other academic)
    Abstract [en]

    We have shown in earlier studies that the local speaking rate influences the perception of quantity in Estonian, Finnish and Norwegian listeners. In the present study, Italian listeners were presented the same stimuli. The results show that the languages differ not only in the relative position – preceding or following – of the units that have the strongest influence on the perception of the target segment, but seemingly also in the width of the reference frame.

    Analytical expressions for the tonotopic sensory scale1990In: Journal of the Acoustical Society of America, ISSN 0001-4966, E-ISSN 1520-8524, Journal of the Acoustical Society of America, ISSN 0001-4966, Vol. 88, no 1, 97-100 p.Article in journal (Refereed)
    Abstract [en]

    Accuracy and simplicity of analytical expressions for the relations between frequency and critical bandwidth as well as critical-band rate (in Bark) are assessed for the purpose of applications in speech perception research and in speech technology. The equivalent rectangular bandwidth (ERB) is seen as a measure of frequency resolution, while the classical critical-band rate is considered a measure of tonotopic position. For the conversion of frequency to critical-band rate, and vice versa, the inversible formula z=[26.81/(1+1960/f )]–0.53 is proposed. Within the frequency range of the perceptually essential vowel formants (0.2–6.7 kHz), it agrees to within ±0.05 Bark with the Bark scale, originally published in the form of a table.

    Articulatory and perceptual factors controlling the age- and sex-conditioned variability in formant frequencies of vowels1984In: Speech Communication, ISSN 0167-6393, E-ISSN 1872-7182, Vol. 3, no 1, 49-61 p.Article in journal (Refereed)
    Abstract [en]

    Speech sounds, as heard by listeners, contain phonetic, personal, and transmission information. The differences between the formant frequencies of vowels spoken by men, women, and children show a fairly uniform tendency in several studies and languages, and they are regarded as personal quality differences. The differences between the sexes are mainly due to the descent of the larynx in males during puberty. The observed tendency in female/male formant frequency ratios is reproduced in a calculation taking into account the physiological consequences of larynx descent and assuming that the vowel specific neural commands to the articulators remain unchanged. The perception of phonetic quality is seen as a process of tonotopic gestalt recognition. The tonality (=critical-band rate) distances between the formants in phonetically identical vowels are claimed and shown to be invariant as long as they are smaller than 6 Bark. The absolute position of the formants allows personal variation. The tonality distance between the first formant and the fundamental is smaller in most vowels spoken by women than in those by men and children. As for the role of the fundamental in this connection, some alternative hypotheses are discussed.

    Clicks and the idea of a human protolanguage2003In: Fonetik 2003: PHONUM 9, 2003, 1-4 p.Conference paper (Other academic)
    Abstract [en]

    In an earlier experiment, the effect of the speech rate of a short preceding or following context was manipulated in addition to the duration of a V, C or VC-sequence that carried a quantity distinction in Estonian words. In order to see to what extent and in which sense the observed perceptual effects are language dependent, the same stimuli were presented to Finns and a subset to Norwegians, representing languages with a different or smaller functional load of quantity distinctions. The results obtained with Estonian and Finnish listeners are compatible with a model of speech perception in which variations in speaking rate are reflected in the pace of an "inner clock" by which listeners measure segment durations. More ‘absolute’ and narrow scoped results obtained with Norwegians are compatible with such a model only if the inner clocks of listeners with a less demanding linguistic background are assumed to resist such influence to a higher degree.

    Coarticulatory effects of consonants on vowels and their reflection in perception1999In: Proceedings from the XIIth Swedish Phonetics Conference, 1999, 141-144 p.Conference paper (Other academic)
    Abstract [en]

    The coarticulatory effects of consonants on vowels may be restricted by the need to keep vowel phonemes distinct. Such restrictions are minimal for the schwa-like vowels in the NW-Caucasian languages and in Northern Chinese, which is shown to display a wide range of such effects. Co-occurrence restrictions and preferences motivated by coarticulatoy ease exist in many languages. Consonant confusions observed in CV- and VC-syllables under various forms of distortion are discussed in order to see the perceptual effects of coarticulation. It is found that listeners tend to ascribe to the consonant some of the properties of the vowel when the consonantal segment is impoverished in information. Such perceptual "reattribution" is likely to be quite important for the perception of spontaneous speech. It is observed that reattribution may also be based on other factors, in addition to coarticulation.

    Conventional, biological and environmental factors in speech communication: a modulation theory.1994In: Phonetica, ISSN 0031-8388, E-ISSN 1423-0321, Vol. 51, no 1-3, 170-83 p.Article in journal (Refereed)
    Abstract [en]

    Speech signals contain various types of information that can be grouped under the headings phonetic, affective, personal, and transmittal. Listeners are capable of distinguishing these. Previous theories of speech perception have not considered this fully. They have mainly been concerned with problems relating to phonetic quality alone. The theory presented in this paper considers speech signals as the result of allowing conventional gestures to modulate a carrier signal that has the personal characteristics of the speaker. This implies that in general the conventional information can only be retrieved by demodulation. In order to perceive the phonetic quality of a speech signal, listeners evaluate the deviations of the properties of the signal (F0, formant frequencies, etc.) from those they expect of a neutral vocalization produced by the speaker with properties given by his age, sex, vocal effort, speech rate, etc. In degraded speech signals, this is shown to result in a perceptual bias towards neutral vowels. It is also argued that speech is perceived on the basis of compatibility testing (and not by optimal matching), so that listeners will hear what they expect to hear as long as they do not notice any counter evidence in the signal.

    Conversational maxims and principles of language planning1991In: Experiments in speech processes / [ed] Olle Engstrand, Catharina Kylander, Mats Dufberg, Stockholm: The Institute of Linguistics, University of Stockholm , 1991, Vol. XII, 25-47 p.Chapter in book (Other academic)
    Abstract [en]

    Striking similarities can be observed between Grice's (1967) conversational maxims and Tauli's (1968) principles of language planning: In order to function well, a language must be such that it makes a well behaved conversation possible. Nevertheless, many ethnic languages as well as constructed interlanguages possess features which are incompatible with these principles. The paper contains an analysis of such cases: The compulsory expression of number and gender, which is in conflict with the principle of facultative precision; ambiguity and lack of distinctiveness in the names of the Latin letters; excessive length of certain morphemes; and restricted freedom to place sentence constituents in a pragmatically adequate order. The compulsory nature of certain distinctions, which cannot be understood on functional grounds, is ascribed to an excessive activity of "universal grammar", which is seen as one of the instincts of human beings. It is further shown that some constructed interlanguages (Volapük and Interlingua) clash with some of Greenberg's (1963) universals concerning the order of meaningful elements. While Esperanto is free from that type of deficiency, it is in conflict with the principle of facultative precision in the same way as most ethnic languages of Europe, as distinct from those of East Asia.

    Cross-modal interactions in visual as opposed to auditory perception of vowels2006In: Fonetik 2006: Working Papers 52, 2006, 137-140 p.Conference paper (Other academic)
    Abstract [en]

    This paper describes two perception experiments with vowels in monosyllabic utterances presented auditorily, visually and bimodally with incongruent cues to openness and/or roundedness. In the first, the subjects had to tell what they heard; in the second what they saw. The results show that the same stimuli evoke a visual percept that may be influenced by audition and may be different from the auditory percept that may be influenced by vision. In both cases, the strength of the influence of the unattended modality showed between-feature variation reflecting the reliability of the information.

    Demodulation, mirror neurons and audiovisual perception nullify the motor theory2007In: Fonetik 2007: TMH-QPSR 50 (1), 2007, 17-20 p.Conference paper (Other academic)
    Abstract [en]

    According to the Motor Theory of Speech Perception (MTSP), listeners perceive speech by way of the articulatory gestures they would perform themselves in producing a similar signal. The theory postulates a module that allows extracting gestural information from the signal. The gestures constitute the event perceived.

    According to the Modulation Theory (MDT), speech is modulated voice. Listeners perceive it by demodulating the signal. The properties of the voice convey nonlinguistic information while the linguistically coded information is conveyed by its modulation. The modulation pattern constitutes the linguistic event perceived.

    The theories agree in requiring a linkage or mapping between perception and production. According to MDT, phonetically labeled links between exteroception and proprioception (mirror and echo neurons) are established in the brain during speech acquisition. The set of links embodies the knowledge of the relation. While MDT describes the device that MTSP would need in order to be implemented, it makes it redundant to recruit the motor system. Demodulation is also necessary in speechreading and in order to perceive sign language, when a face or body is 'modulated’ instead of a voice. In audiovisual speech perception, there are two percepts: a normally dominant vocal one and a gestural one that does not need to agree with it. MTSP knows of only one of these. It is concluded that all the specific claims of MTSP are false while MDT rests on ‘first principles’.

    Abstract [en]

    The distances between neighbouring partials of vowels are in many cases larger than the bendwidths of the formants and also often larger than the critical bandwidth (1 Bark). Several results of different experiments with synthetic one- and two-formant vowels suggest that an efficient bandwidth of resolution of roughly 3 Bark is basic to the perception of spectral features of vowels. A corresponding spectral dispersion or integration did not, however, appear in experiments with non-speech harmonic sounds. K. Benedini investigated the timbre differences between harmonic sounds with up to six harmonics of 100 Hz. An analysis of the estimated timbre differences shows that both the bandwidth of resolution and the perceptual weight of the partials is proportional to their frequency. The weight of the fundamental is, however, substantially increased in comparisons between residual and complete harmonic sounds. Further, the perceived difference between two sounds turns out to be dependent on the remaining sounds presented in a perceptual experiment. The timbre differences between low-passed harmonic sounds of different width can be accounted for exclusively on the basis of the tono-topical distances between the upper flanks of these sounds. It is concluded that the judgement of differences in timble involves the prior extraction, induced by context, of relevant dimensions. The bandwidth of spectral resolution that appears with the perception of vowel-like sounds may in part be due to an intrincsic inacuity to the phonetic templates supposedly stored in memory.

    Distinctive names for speech sounds and letters obtained with hyper-coarticulated vowels1999In: Proceedings of the XIVth ICPhS, San Francisco, 1999, 1125-1128 p.Conference paper (Other academic)
    Abstract [en]

    The names used in most languages for the letters of the Latin alphabet and for the sounds these represent are marked by a lack of distinctiveness that often makes them fail their purpose. Various auxiliary "spelling alphabets" are used in such cases. No such need arises with the letter names that are used for the Arabic, Hebrew, Armenian and Greek alphabets. Short and yet distinctive names for consonants can, however, be coined with a minimum of arbitrariness by exploiting the coarticulatory effects of consonants on vowels. These are analyzed for schwa-like vowels in the permissive vowel systems of NW-Caucasian and Mandarin Chinese, and it is shown how they can be utilized to coin names for phones and letters, especially for Turkish.

    Evidence for demodulation in speech perception2000In: Proceedings of the 6th ICSLP, 2000, 790-793 p.Conference paper (Other academic)
    Abstract [en]

    According to the Modulation Theory, speakers modulate their voice with linguistic gestures, and listeners demodulate the signal in order to separate the linguistic from the expressive and organic information. Listeners tune in to the carrier (the voice) on the basis of an analysis of a stretch of speech and they evaluate its modulation. This is reflected in many perceptual experiments that involved manipulated introductory phrases, blocked vs. randomized speakers, and other non-linguistic variables.

    Factors affecting visual influence on heard vowel roundedness: Web experiments with Swedes and Turks2009In: Proceedings FONETIK 2009: The XXIIth Swedish Phonetics Conference, held at Stockholm University, June 10-12, 2009, Stockholm, 2009, 166-171 p.Conference paper (Other academic)
    Abstract [en]

    The influence of various general and stimulus-specific factors on the contribution of vision to heard roundedness was investigated by means of web experiments conducted in Swedish. The original utterances consisted of the syllables /ɡyːɡ/ and /ɡeːɡ/ of a male and a female speaker. They were synchronized with each other in all combinations, resulting in four stimuli that were incongruent in vowel quality, two of them additionally in speaker sex. One of the experiments was also conducted in Turkish, using the same stimuli. The results showed that visible presence of lip rounding has a weaker effect on audition than its absence, except for conditions that evoke increased attention, such as when a foreign language is involved. The results suggest that female listeners are more susceptible to vision under such conditions. There was no significant effect of age and of discomfort felt by being exposed to dubbed speech. A discrepancy in speaker sex did not lead to reduced influence of vision. The results also showed that habituation to dubbed speech has no deteriorating effect on normal auditory-visual integration in the case of roundedness.

    Abstract [en]

    Is there a steady transition between unrounded, 'outrounded', and 'inrounded' Swedish vowels, or are these distinct categories? By which articulatory parameters can these distinctions be described? These questions, actualised through confusion data in speechreading, are answered by means of articulatory measurements of lip-opening, lip-protrusion, and jaw-lowering in 4 subjects. It is found, i.a., that rounded and unrounded vowels form clearly separated categories, and that inrounded vowels, including /o/, are distinguished from outrounded ones by their smaller lip-opening and, if long, by increased lowering of the jaw.

    On Vowels : Spectral Features, Related Aspects of Production and Sociophonetic Dimensions1983Doctoral thesis, monograph (Other academic)
    Abstract [en]

    The first and major part of this thesis deals with spectral features of vowels and with the distinction of phonetic information from personal and transmittal information also conveyed to listeners by speech sounds. The results of perceptual experiments with synthetic vowels whose fundamental and first formant were varied in frequency suggested that the smaller tonotopical distances between formants (< 6 Bark) are invariant in phonetically idenctical vowels produced by male and female speakers of several languages. It is further investigated how partials are resolved in the process of timbre perception. Previous experiments by other researchers suggest an effective bandwidth close to three Bark. In similar experiments, though using different stimuli, this result could not be replicated. A re-analysis of some other experimental results gave, among other details, effective bandwidths roughly proportional to frequency in the range below 600 Hz. Due to contextual effects, the general validity of this result is in question. The non-uniform sex-differences in formant frequencies are shown mainly to be consequences of an anatomical development in accord with the perceptual condition of invariant phonetic qualities.

    The second part of the thesis, Vocalism in Eastern Central Bavarian, represents a case study of the realization of sociophonetic dimensions in speech. In the chosen group of dialects some phonological rules lead to a richly shadowed vowel system. The application of these rules is investigated with respect to dialectal, sociolectal, speaker age, and speech tempo variation.

    Paralinguale Phänomene: (Paralinguistic phenomena)2005In: SOCIOLINGUISTICS / SOZIOLINGUISTIK: An International Handbook of the Science of Language and Society / Ein internationales Handbuch zur Wissenschaft von Sprache und Gesellschaft, 2nd ed., Walter de Gruyter, Berlin/New York , 2005, Vol. 1, 653-665 p.Chapter in book (Other academic)
    Abstract [en]

    Paralinguistic phenomena are those phenomena that can be observed in speech (Saussure's 'parole') but that do not belong to the arbitrary conventional code of language (Saussure's 'langue'). The paralinguistic features of speech play, nevertheless, an important role in speech communication, and there are no speech signals without such features. However, the distinction linguistic vs. paralinguistic applies not only to speech but to gestural language as well, and it is not bound to any sensory modality. The chapter distinguishes between (1) perspectival, (2) organic, (3) expressive and (4) linguistic aspects. Under (1), spatial hearing, distance perception, spectral distortion, and helium speech is mentioned. Under (2), sex differences (also in energy balance and in liveliness) and the articulatory and acoustic effects (on F0, formant frequencies etc.) of the ontological development of the organ of speech are considered as well as the perception of speakers' age and sex. The phylogeny of the sex-differences is also considered. Under (3), it is considered how a speaker's emotions and attitudes affect the properties of speech signals and how they are recognized by listeners. This includes an account for the "Frequency Code" (Ohala, 1984) and for the acoustic effects of variations in vocal effort. The following topics are also mentioned: Personality inference from voice quality; Baby-talk; semantically empty linguistic vehicles of expressive information; cases in which both a linguistic contrast and a paralinguistic continuum is involved. Under (4), the problem of how listeners extract the linguistic-phonetic information from speech signals is considered, and the normalization, search for invariance and modulation/demodulation approaches are mentioned. The paralinguistic origin of many prosodic features of languages is mentioned as well as onomatopoeia and sound symbolism and its basis in associations.

    Perception of speaker sex, age, and vocal effort1997In: Fonetik 1997: Phonum 4, 1997, 183-186 p.Conference paper (Other academic)
    Abstract [en]

    Speech material recorded for the purpose of studying the acoustic properties of speech as a function of speaker sex, age, and vocal effort (induced by varying the distance between the speaker and the person spoken to over a wide range) was used in perception experiments in which the subjects had to rate either the distance between speaker and adressee or the age and the sex of the speaker. The correlations between these percepts and gross spectral and temporal properties of the utterances, such as the mean values of F0, F1, and F3, spectral emphasis and utterance duration were analysed.

    Abstract [en]

    It is shown that the energy required in order to articulate manual and oral gestures at a given rate varies in proportion with the fifth power of linear body size, while the energy supply varies with its second power. This provides for a better understanding of the differences in peripheralness observed in the formant frequencies of vowels in speech articulated more or less forcefully by men, women and children.

    Abstract [en]

    After a short introduction to the phenomenon of sound symbolism, its possible effects on the proximal and distal demonstratives and the personal pronouns of the first and second person are investigated. For this purpose, word pairs in which there is a straight forward difference that is compatible with or contrary to the expectations suggested by sound symbolism have been counted. Forms with a common etymology have been taken as a single case. The results confirm that vowels in proximal demonstratives tend to have a higher 'sibilant pitch', or F2', than do those in the distal demonstratives of the same languages, and they show that such forms have an advantage in their struggle for existence in languages. Counterexamples are found only in languages with a small number of speakers. It is, further, found that nasals are preferred in first person pronouns while stops and other obstruents are preferred in second person pronouns. This is attributed to the proprioceptive qualities of these classes of speech sounds. In addition, it is suggested that association with lingual or labial pointing gestures may affect the preferences of consonants. It is observed that the pronouns of most language groups of Europe and Northern Asia are likely to be etymologically related, while sound symbolism may have contributed to the survival of their similarities. It is, however, also shown that similarities that have been taken as evidence for far-reaching genetic relationships can sometimes be readily understood as genetically independent reflections of universal sound symbolism.

    Acoustic effects of variation in vocal effort by men, women, and children.2000In: J Acoust Soc Am, ISSN 0001-4966, Vol. 107, no 6, 3438-51 p.Article in journal (Refereed)
    Abstract [en]

    The acoustic effects of the adjustment in vocal effort that is required when the distance between speaker and addressee is varied over a large range (0.3-187.5 m) were investigated in phonated and, at shorter distances, also in whispered speech. Several characteristics were studied in the same sentence produced by men, women, and 7 year-old boys and girls: duration of vowels and consonants, pausing and occurrence of creaky voice, mean and range of F0, certain formant frequencies (F1 in [a] and F3), SPL of voiced segments and [s], and spectral emphasis. In addition to levels and emphasis, vowel duration, F0, and F1 were substantially affected. “Vocal effort” was defined as the communicational distance estimated by a group of listeners for each utterance. Most of the observed effects correlated better with this measure than with the actual distance, since some additional factors affected the speakers’ choice. Differences between speaker groups emerged in segment durations, pausing behavior, and in the extent to which the SPL of [s] was affected. The whispered versions are compared with the phonated versions produced by the same speakers at the same distance. Several effects of whispering are found to be similar to those of increasing vocal effort.

    The frequency range of the voice fundamental in the speech of male and female adults1993Other (Other academic)
    Abstract [en]

    Published data on the frequency of the voice fundamental (F0) in speech show its range of variation, often expressed in terms of two standard deviations (SD) of the F0-distribution, to be approximately the same for men and women if expressed in semitones, but the observed SD varies substantially between different investigations. Most of the differences can be attributed to the following factors: SD is increased in tone languages and it varies with the type of discourse. The more ‘lively’ the type of discourse, the larger it is. The dependence of SD on the type of discourse tends to be mom pronounced in the speech of women than of men. Based on an analysis of various production data A is shown that speakers normally achieve an increased SD by increasing the excursions of F0 from a ‘base-value’ that lies about 1.5 SD below their mean F0. This is relevant to applications in speech technology as well as to general theories of speech communication such as the ‘modulation theory’ in which the base-value of F0 is seen as a carrier frequency.

    The perceptual evaluation of F0 excursions in speech as evidenced in liveliness estimations.1995In: J Acoust Soc Am, ISSN 0001-4966, Vol. 97, no 3, 1905-15 p.Article in journal (Refereed)
    Abstract [en]

    In order to learn how listeners evaluate F0 excursions, a set of experiments was performed in which subjects had to estimate the liveliness of utterances. The stimuli were obtained by LPC analysis of one natural utterance that was modified by resynthesizing F0 , the formant frequencies, and the time scale in order to simulate some of the natural extra- and paralinguistic variations that affect F0 and/or liveliness, namely the speaker's age, sex, articulation rate, and voice register. In each case, the extent of the F0 excursions was varied in seven steps. The results showed that, as long as the stimuli appeared to have been produced in the modal register (of men, women, and children), listeners judged F0 intervals to be equivalent if they were equal in semitones. When the voice register was shifted without adjustment in articulation , listeners appeared to judge the F0 excursions in relation to the spectral space available below F1 . The liveliness ratings were found to be strongly dependent on articulation rate and to be affected by the perceived age of the speaker which, with the manipulated stimuli used here, turned out to be significantly affected by the sex of the listener.

    Perception of speaker age, sex and vowel quality inves­tigated using stimuli produced with an articulatory model2003In: Proceedings of the XVth ICPhS, 2003, 1739-1742 p.Conference paper (Other academic)
    Abstract [en]

    This paper deals with the perception of linguistic and paralinguistic qualities conveyed by synthetic vowels produced with an articulatory model in which transfer func­tions of the French vowels /i y e ø E œ/ characteristic of five growth stages were each combined with five different F0 values. Listeners had to judge the speaker's age and sex in addition to vowel quality. Four subgroups of listeners were distinguished, according to sex and frequency of contact with children. The results were subjected to regression analy­sis based on ctitical band rate (z) and logarithmic values of F0, F1 to F5 and calculated values of F2’. This showed (Z1 -0.6 Z0) to correlate highly with vowel openness and 0.8 (Z4 -Z3) with roundedness in addition to Z2'. F0 and the formants above F1 contributed equally to age percep­tion. There were slight but significant differences between listener groups and there was a tendency to perceive vowels as produced by a younger speaker when perceived as rounded - older when not. This can be understood as due to a choice listeners have in interpreting lower formants as due to liprounding or a permanently longer vocal tract indicative of a higher age.

    The effect of local speaking rate on the perception of quantity in Estonian.2003In: Phonetica, ISSN 0031-8388, Vol. 60, no 3, 187-207 p.Article in journal (Refereed)
    Abstract [en]

    The Estonian language with its elaborate system of contrasts in quantity, whose essentials are described in the paper, is used to investigate human perception of distinctive contrasts in the duration of vowels, consonants and larger units. In the experiments reported, the speaking rate of a preceding or following syllable was manipulated in addition to that of a target V, C or VC sequence that carried a quantity distinction in disyllabic words. The results confirmed that the second syllable in such words, in particular the duration of its vowel, serves as a reference, but they showed segments of additional syllables to contribute in the same direction. The results provided no support for ascribing quantity to any larger units than phonetic segments. Speech rate effects of similar magnitude have been observed in Japanese, while effects of the same kind were found to be smaller in Dutch. These differences may be linked with the functions durational contrasts have in the different languages. It appears that listeners have to adapt more fully to variations in the local speaking rate when there are no additional cues and the functional load of quantity distinctions is high.

    Local speaking rate and perceived quantity2003In: Fonetik 2003: PHONUM 9, 2003, 41-44 p.Conference paper (Other academic)
    Abstract [en]

    In an earlier experiment, we have shown that the local speaking rate affects the perception of quantity of Estonian listeners. In order to see if this effect is language dependent, we presented the same stimuli to Finns and a subset to Norwegians, whose languages have a different and smaller functional load of quantity distinctions. The results obtained with Estonian and Finnish listeners are compatible with a model of speech perception in which variations in speaking rate are reflected in the pace of an "inner clock" by which listeners measure segment durations. More 'absolute' and narrow scoped results with Norwegians are compatible with such a model only if the inner clocks of listeners with a less demanding linguistic background are assumed to resist such an influence to a higher degree.

    Perceptual relativity in identification of two-formant vowels1987In: Speech Communication, ISSN 0167-6393, E-ISSN 1872-7182, Vol. 6, no 2, 143-157 p.Article in journal (Refereed)
    Abstract [en]

    It is attempted to reduce the phonetic quality of vowels to the positions of the peaks in their tonotopical spectra relative to the other peaks, simultaneous or preceding in context. Synthetic two-formant vowels were identified by speakers of languages that differentiate richly among high vowels (Swedish, Turkish). The parameters F1 (204-801 Hz) and F2' (509-3702 Hz) were systematically varied in steps of 0.75 critical bandwidth. F0 was kept close below F1 in all vowels. These were presented in two orders with subsequently rising or falling F2'. Most subjects heard predominantly close vowels. The "isophones" of most subjects could be described in a uniform manner implying a normalization with respect to two reference points, one at a distance of 3 critical bands above F0 and the other one at an absolute position corresponding to 2.8 kHz. It is speculated that this second reference point might represent a default position of the third formant or the like.
