Abstract
The purpose of this study was to replicate and extend the classic study of vowel transition. The present study investigated the developmental changes in vowel transition in Garhwali in normal subject. Vowel transition is one of the acoustical cues that provide information about speech intonation. Intonation contours contribute to information about the prosodic structure of an utterance. In tonal languages, linguistic information is also carried in the intonation contours of speech. Thus, sensitivity to speech intonation is an important aspect of speech perception. This paper presents a study of Vowel transition of Garhwali Hindi syllables abutted with ten vowels / a, a:, i, i:, u, u:, e, e:, o, o:/ of different position of the words i.e. initial, middle and final position. These tokens were spoken in isolation by 15 adult male and 15 adult female speakers. These speakers were different district of Uttarakhand and they all are native Garhwali speaker. Garhwali Hindi is a regional dialect of Uttarakhand. Male speaker has the higher Vowel transition than female native speaker. The effect of aspiration on vowel transition for aspirated and unaspirated sounds have been measured and it was found that unaspirated voice sound has higher vowel transition than unaspirated voiceless sounds and also found that aspirated voice sound has higher vowel transition than aspirated voiceless sounds for both male and female speakers.
