摘要：Prosody refers to structure of sound and rhythm
and both are essential parts of speech processing applications. It
comprises of tone, stress, intonation and rhythm. Pitch and
duration are the core elements of acoustic and that information
can make easy to design and development for application
module. Through these two peculiarities, the prosody module can
be validated. These two factors have been investigated using the
sounds of Sindhi adults and presented in this paper. For the
experiment and analysis, 245 male and female undergraduate
students were selected as speakers belonging from five different
districts of upper Sindh and categorized into groups according to
their age. Particular sentences were given and recorded
individually from the speakers. Afterward, these sentences
segmented into words and stored in a database consisting of 1960
sounds. Thus, distance of the frequency in pitch was measured
via Standard Deviation (SD). The lowest Mean SD accompanied
0.25Hz and 0.28Hz received from male and female group of
district Sukkur. The highest Mean SD has measured with male
and female group of district Ghotki along 0.42Hz and 0.49Hz.
Generally, the pitch of female’s speakers was found high in
contrast to male’s speaker by 0.072Hz variation.
