Exploring consequences of short- and long-term deafness on speech production: A lip-tube perturbation study.

Exploring consequences of short- and long-term deafness on speech production: A lip-tube perturbation study. Clin Linguist Phon. 2015 Feb 6;:1-23 Authors: Turgeon C, Prémont A, Trudeau-Fisette P, Ménard L Abstract Abstract Studies have reported strong links between speech production and perception. We aimed to evaluate the role of long- and short-term auditory feedback alteration on speech production. Eleven adults with normal hearing (controls) and 17 cochlear implant (CI) users (7 pre-lingually deaf and 10 post-lingually deaf adults) were recruited. Short-term auditory feedback deprivation was induced by turning off the CI or by providing masking noise. Acoustic and articulatory measures were obtained during the production of /u/, with and without a tube inserted between the lips (perturbation), and with and without auditory feedback. F1 values were significantly different between the implant OFF and ON conditions for the pre-lingually deaf participants. In the absence of auditory feedback, the pre-lingually deaf participants moved the tongue more forward. Thus, a lack of normal auditory experience of speech may affect the internal representation of a vowel. PMID: 25658492 [PubMed - as supplied by publisher]
