Abstract
Palatoglossus EMG potentials and voice were recorded while a native speaker of Hindi produced CVC nonsense utterances where C was /s/ and V was one of the vowels /iιeɛəɑɔoɷu,ĩι̃ẽɛ̃ə̃ɑ̃õñɷ̃Ũ/. Preliminary results show low levels of EMG activity for the front oral vowels, whereas for the central and back oral vowels the EMG activity is considerable. All nasal vowels exhibit a high level of EMG activity, except /ẽ, ɛ̃/ for which the EMG activity is minimal. EMG levels for the central and back nasal vowels are considerably higher than those for the front nasal vowels. EMB levels for the nasal vowels /õ, ñ, ɷ̃, Ũ/ are comparable to those for the oral vowels /ɔ, o, ɷ, u/, respectively. However, the EMG levels for the nasal vowels /ĩ, ι̃, ə̃, ã/ are considerably greater than for the comparable oral vowels /i, ι, ə, ɑ/. Furthermore, the patterns of EMG potentials for the long vowels differ from those for the short vowels irrespective of their being oral or nasal.
