Abstract
This study was designed to investigate the relationship between pitch deviancy and intelligibility of deaf children's speech. Ratings of pitch and overall intelligibility of the children's spontaneous speech were obtained from three listeners familiar with the speech of the deaf. The rating scales used were from the Communication Profile developed at the National Technical Institute for the Deaf (D. Johnson, Proceedings of the Institute on Rehabilitative Audiology, July 1974). Preliminary results suggest that speech intelligibility and pitch deviancy are not significantly correlated. The relationship between rate d pitch deviancy and deviance of the fundamental frequency as measured by spectrographic analysis will be discussed. Analysis of the interaction between pitch deviancy, speech intelligibility, and hearing level will also be presented.
