Influence of consonant environment on duration of vowels produced by normal-hearing, hearing-impaired, and deaf adult speakers

Abstract

The results of the present study have revealed that in a normal-hearing and a hearing-impaired population, vowels are significantly longer in duration in voiced-consonant environment, when compared with a voiceless environment. Vowels were also significantly longer in duration in a fricative environment when compared to a plosive environment. For a deaf population, the same trends were evident although the differences were not significant. Subject Classification: [43]70.40, [43]70.75, [43]70.70; [43]65.64.
