Author(s): Dinesh Sheoran, Pardeep Sangwan, Manoj Khanna
Abstract: In the present era, speech processing technology has made use in various applications namely “Speech enhancement”, “Speech compression”, “Speech recognition” and “Speech synthesis” etc. In the current work, issues related to speech recognition system and the role of feature extraction has been studied in detail. This study includes speech feature extraction using Linear Predictive Coefficients, Cepstral analysis for extensive digits database. The results presented prove the superiority of MFCC feature extraction technique.
