United States accents compared: the relation of acoustic distances and perceptual tasks
2015 (English)Conference paper, Abstract (Refereed)
This project investigates correlations between accent production and perception by comparing two sets of data: acoustic distances of American dialectal speech samples, measured using Euclidean distances of each vocalic stimuli's first three formants across a trajectory, and perceptual data in the form of online survey material and EEG tests which judge the differences between the same varieties. The speech samples used consist of six sentences from eight regions of the United States, each sentence containing phonological features that may be marked as perceptually relevant for dialect classification.Here we examine the preliminary outcomes from such perceptual tests performed by naïve listeners, which include free classification, identification, perceived difference and ranking similarity, as well as attitude judgement tasks. Additionally, EEG tests were carried out to evaluate the relation between acoustic distance of accents and ERPs. Of special interest here is the relation between a non-regionally specified American accent and others. This “standardized” variety is judged in comparison with each of the regional accents in order to investigate listeners’ perceptions of non-regional vs. regional accents, and in turn the correlation between measured accent (dis)similarity and perception.
