Abstract
The overall goal of this study is to examine the intelligibility differences of clear and conversational speech and also to objectively analyze the acoustic properties contributing to these differences. Seventeen post-lingual stable sensory-neural hearing impaired listeners with an age range of 17–40 years were recruited for the study. Forty Telugu sentences spoken by a female Telugu speaker in both clear and conversational speech styles were used as stimuli for the subjects. Results revealed that mean scores of clear speech were higher (mean = 84.5) when compared to conversational speech (mean = 61.4) with an advantage of 23.1% points. Acoustic properties revealed greater fundamental frequency (f0) and intensity, longer duration, higher consonant–vowel ratio (CVR) and greater temporal energy in clear speech.
