15th International Congress of Phonetic Sciences (ICPhS-15)
A 96-channel electropalatograph was used to obtain palatometric measures on the area of tongue-palate contact, the A-P (anterior-posterior) location (place) and the A-P length of the central constriction for the apicoalveolar nasal /n/, lateral /l/ and trill /r/. Bisyllabic nonsense words of the form /bi-ib/, /bu-ub/ and /ba-ab/ containing above consonants before a stressed vowel in the symmetrical vocalic context and embedded in a carrier sentence were produced by a native speaker of Hindi. Results showed that the area of contact and the A-P length of the central constriction decreased from /n/ to /l/ to /r/. The A-P location (place) of the central constriction for /n/ and /l/ shifted backward from /i/ to /a/ to /u/ context, indicating that these consonants are not resistant to the coarticulatory effects of the vocalic context. However, the A-P location (place) of the central constriction for /r/ showed no sensitivity to the coarticulatory effects of the surrounding vowels.
