Analysis of Temporal parameters in the Speech of the Children with Hearing Loss

ABSTRACT

The surge of literature indicates that the to develop more effective speech training procedures for the subjects with hearingloss, it is necessary to study the deviation in their speech from that of the normal-hearing subjects and hence, the analysis ofspeech of the subjects with hearing loss becomes essential. The current investigation aimed at studying the temporalparameters of vowel and consonants in the speech in children with hearing loss. Sixteen bisyllabic words with stopconsonants and vowels, uttered by participants with severe sensorineural hearing loss and age and gender-matched normalhearing participants in the age range of eight to ten years were recorded and the temporal parameters namely vowel duration,closure duration, consonant duration, voice onset time, burst duration, and word duration were analysed acoustically. Resultsof statistical analyses revealed that there were significant differences in vowel duration, voice onset time, closure durationand consonant duration between the participants of two groups. No differences in burst duration were observed between theparticipants of both groups.
