Abstract

Sindhi is one of the official languages spoken in the Sindh province of Pakistan, and in some parts of India. This paper aims to determine the existence of diphthongs in the language inventory. Acoustic analysis has been carried out for twenty seven diphthong words selected in two different ways; (i) (diphthong-) words in isolated utterances and (ii) (diphthong-) words embedded in a sentence (carrier sentence), read by a speaker. The voice-samples were collected from ten native male speakers from the Sindh region in Pakistan. The main acoustic parameters tested for each diphthong occurrence are the formant frequencies, the fundamental frequency, and the duration.
