A Review on Acoustic Phonetic Approach for Marathi Speech Recognition

Abstract

This paper discusses the phoneme used in Marathi language as a possible basic unit of speech recognition, for which there is some empirical psychoacoustic support in the case of human and some engineering justification in the case of machines striving to imitate human abilities. For the purpose of the research described in this paper, a basic unit of speech recognition is the intermediate form of speech information around which much of the recognition processing is organized for human beings or for machines. The general opinion of phonetician and psycholinguists is that there is indeed such a unit with relatively few distinct types 1. For this research a basic unit is ideally an output of acoustic-phonetic processing and an input to the lexical processing stages.
