Abstract

Vowel duration, one of the important acoustic characteristics, is important in vowel perception. Vowel duration varies based on individual, linguistic and non-linguistic characteristics. This study was to study vowel duration in all Telugu vowels across different gender, region and age groups. Using cross sectional study design, a total of 4320 tokens from 72 randomly selected Telugu speaking participants from three age groups, two gender and three region groups were analyzed. Vowel duration of the target vowel was extracted and analyzed using spectrogram. From the results it is interpreted that significant variations in vowel duration of vowels in Telugu exist between children, adolescents and adults; Coastal, Rayalaseema and Telengana speakers. Vowels /e/ and /a:/ had longest vowel duration, while short and long vowels /i/ have shortest vowel duration. Children found to have longer vowel duration as compared to adolescents or adults. Regional influences are seen on vowel duration. Rayalaseema speakers have longer vowel duration as compared to Coastal or Telengana speakers. Hence, it is essential for speech language pathologists to apply the age, gender and region appropriate normative data to achieve appropriate speech output.
