Speech Compensation To Formant Perturbations In English And Vietnamese Talkers, Linh L.T. Nguyen

Electronic Thesis and Dissertation Repository

The purpose of this experiment was to examine mechanisms underlying the auditory feedback system using Vietnamese and English talkers in response to feedback perturbations. F1 discrimination thresholds, vowel goodness ratings, and vowel category bounds for English /ɪ/ were determined. Vowel spaces were collected for both languages and auditory feedback of F1 was manipulated for English and Vietnamese vowels. Speech compensation during perturbed auditory feedback occurred in English and Vietnamese vowels suggesting that the underlying mechanisms are universal. However, there were differences in speech compensation for some vowel conditions, which may have occurred due to vowel location in each language group’s …
