Abstract

In this paper several speech features that could best represent a set of isolated words are compared. Features are derived from the power spectrum, the spectrogram, and the linear predictive code (LPC). Using a k-nearest neighbor classifier, we have obtained best results of 99.8% for the recognition rate when the features were obtained using LPC coefficients.
