In this paper we investigate the performance of the Discrete Wavelet Transform (DWT) with Dynamic Time Warping , Vector Quantization and Artificial Neural Networks for speaker-dependent, isolated word recognition. Wavelet Transforms have demonstrated good time-frequency localization properties and are appropriate tools for the analysis of non-stationary(More)
