Review on Speech Recognition

The most common way of communication between human being is speech. With this speech human can communicate, interact with the machine also .So, automatic speech recognition has lot of popularit y. This paper gives an overview of the speech recognition s ystem and its progress till date . This paper helps in selecting the technique along with their relative merits &demerits. The aim of this paper is to compare some of t he well known methods used in various stages of speech recognition system. For Feature extraction of speech MFCC has been used which gives set of feature vectors of spe ech waveform. Also from this paper we have seen various feature recognition technique and we have seen amongst that HMM and VQ is used most recently .
