Abstract
Speech recognition is a process to identify the speaker on the basis of individual information within the speech wave. Recent development has made the voice recognition in the security system. In this paper the implementation of speech digit recognition system is discussed. This technique is mainly used in person voice identification and control access like banking by telephone, voice dialing and database access services. The zero to nine digit utterances for speech data was collected. The speech digit recognition mainly involves two parts, one is the feature extraction and other one is the feature matching. The main approach is to isolate the speech recognition by Cepstrum and vector quantization. Cepstrum technique is used for feature extraction and vector quantization is used for feature matching. The result show that all digit gives good performance. The proposed speech digit recognition algorithm is implemented by using MATLAB software.
