Abstract: Hearing loss, deafness, hard of hearing and hearing impairment are the various terms used in the deaf community as a condition for inability to hear either partial or total impairment. The hearing loss in most of the deaf persons affects the language development to lead a normal life. The acoustic characteristic of deaf speaker is estimated in comparison with the normal speakers to create an assistive method. The speech signals are procured from the 32 territory-specific normal and deaf speakers by uttering ten Tamil words. The parameters analysed are pitch, formants, jitter and shimmer. From the overall results, it is observed that acoustic characteristics differ significantly for the deaf speakers and the quantitative values of the parameters are controlled by the normal speakers. Further the acoustic parameters may be used as a correction factor for the deaf speech signal such that the listeners can understand the deaf speech.
