Manipulation Of Auditory Feedback In Individuals With Normal Hearing And Hearing Loss, Le Truc Linh Vaccarello
Electronic Thesis and Dissertation Repository
Auditory feedback, the hearing of one’s own voice, plays an important role in the detection of speech errors and the regulation of speech production. The limited auditory cues available with a hearing loss can reduce the ability of individuals with hearing loss to use their auditory feedback. Hearing aids are a common assistive device that amplifies inaudible sounds. Hearing aids can also change auditory feedback through digital signal processing, such as frequency lowering. Frequency lowering moves high frequency information of an incoming auditory stimulus into a lower frequency region where audibility may be better. This can change how speech sounds …

Investigation Of Auditory Encoding And The Use Of Auditory Feedback During Speech Production, Laura E. Beamish
Electronic Thesis and Dissertation Repository
Responses to altered auditory feedback during speech production are highly variable. The extent to which auditory encoding influences this varied use is not well understood. Thirty-nine normal hearing adults completed a first formant (F1) manipulation paradigm where F1 of the vowel /ε/ was shifted upwards in frequency towards an /æ/–like vowel in real-time. Frequency following responses (FFRs) and envelope following responses (EFRs) were used to measure neuronal activity to the same vowels produced by the participant and a prototypical talker. Cochlear tuning, measured by SFOAEs and a psychophysical method, was also recorded. Results showed that average F1 production changed to …
Speech Compensation To Formant Perturbations In English And Vietnamese Talkers, Linh L.T. Nguyen
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 …
