Phonetics and phonology are very interesting areas of Linguistics, and are interrelated. They are based on the human speech system, speech perception, native speakers’ intuition, and vocalic and consonantal systems of languages spoken in this world. There are more than six thousand languages spoken in the world. Every language has its own phonemic inventory, sound system, and phonological and phonetic rules that differ from other languages; most even have distinct orthographic systems. While languages spoken in developed countries are well-studied, those spoken in underdeveloped countries are not. There is a great need to examine them using a scientific approach. These under-studied languages need to be documented scientifically using advanced technological instruments to bring objective results, and linguistics itself provides the scientific basis for the study of a language. Most research studies to date have also been carried out with reference to old or existing written literature in poetry and drama. In the current era of research, scholars are looking for objective scientific approaches, e.g., experimental and instrumental studies that include acoustic research on the sound systems of less privileged languages spoken locally in developing countries. In this context, Sindhi is an example of this phenomenon, and un-researched with reference to syllable structure and the exponents of lexical stress patterns.
