Sibilant Production in Speakers Who Have Hearing Loss: Electopalatograhic and Perceptual Evidence
McGarr, Nancy S.; Raphael, Lawrence J.; Kolia, Betty; Vorperian, Houri K.; Harris, Katherine
Volta Review, v104 n3 p119-140 2004
Using electopalatography, this study investigated the production of sibilants produced by four adults who have severe-to-profound hearing loss and four speakers with normal hearing. Each speaker wore a Rion[R] semi-flexible electroplate while producing multiple repetitions of the utterances "see, sue, she, shoe." The speakers' productions were subjected to perceptual judgments by non-expert listeners. Analysis of the electropalatographic data showed the expected differences in the palatal regions contacted by the tongue for /s/ versus /[esh]/, as well as for /i/ versus /u/ for the speakers with normal hearing. The corresponding linguapalatal contact patterns were different for the speakers with hearing loss, and, compared to the speakers with normal hearing, involved slower cross-segmental tongue movements, reduced differentiation of linguapalatal contact across segments, and reduced segmental influences on coarticulation. The electropalatographic data were in approximate agreement with the perceptual data.
