Abstract
The question posed is whether interarticulator timing relationships are preserved in deaf speakers across speech transformations such as those induced by phonetic context and stress. Acoustic recordings were obtained simultaneously with kinematic records of lip and jaw motions using the Selspot infrared tracking device. The experimental corpus included real word utterances with a medial labial consonant (p,b,m,w,f,v) flanked by one high and one low vowel (e.g., “And Bea pops it”). The stimuli were produced by one hearing and three hearing‐impaired talkers. Measures of jaw and lip displacement and velocity of movement were made in order to address questions of kinematics as a function of stress, phonetics, and vowel effects. Results for the hearing speaker showed the expected systematic differentiation of stressed and unstressed syllables. Preliminary results for the hearing‐impaired speakers showed the relative interarticulator timing was more variable than the normal. However, the deaf speakers were like normal in that they differentiated vowels on the basis of jaw placement. These and other measures to investigate phonetic effects will be presented.
