Isolated Speech Recognition Using MFCC and DTW
In this paper, the authors describe an approach of isolated speech recognition by using the Mel-scale Frequency Cepstral Coefficients (MFCCs) and Dynamic Time Warping (DTW). Several features are extracted from speech signal of spoken words. An experimental database of total five speakers, speaking 10 digits each is collected under acoustically controlled room is taken. MFCC are extracted from speech signal of spoken words. To cope with different speaking speeds in speech recognition Dynamic Time Warping (DTW) is used.
