Experimental phonetics

The acoustic study of speech provides a scientific method to conduct an

objective analysis of speech sounds by measuring physical properties of sounds
and their acoustic realizations. As discussed in the literature review, the

measurements of these sound properties, i.e., formants (F1 and F2), duration, and

intensity, are then used to investigate the sound pattern of a language. Similarly,

this study carried out an acoustic analysis of phonetic measurements of lexical

stress in Sindhi using the following: (a) Duration of stressed vs. unstressed vowels, (b) Duration of stressed vs. unstressed stop closures, (c) Formant frequency (F1)
