چکیده
Abst rac t Experimental results of the quantization of Linear Predictive Coded (LPC) coefficients using two general approaches, scalar coefficient quantization and vector quantization, are presented. The LPC coefficients were quantized in several domains: Line Spectral Frequency (LSF), cepstral, predictor, reflection and autocorrelation. Two distortion measures were used to evaluate the quantizers; Itakura-Saito and RMS log spectral distortion measure. The vector quantizers showed good results for only 9 bits per frame of 150 speech samples.

This paper presents Thai monophthongs recognition. The monophthongs were qualitatively recognized by the 3-state leftto-right continuous density hidden Markov model. The LPC cepstral coefficients were used as feature which represented specch signal. The temporal cepstral derivative was additionally utilized in order to compare efficiency of the additional feature with that of the single LPC cep...

In this paper, the performance of Perceptual Linear Prediction (PLP) features has been compared with the performance of Linear Prediction Coefficient (LPC) features for speaker identification. Two classification techniques, Gaussian Mixture Models (GMM) and Vector Quantization (VQ) with Dynamic time wrapping (DTW) are used for classification of speakers based on their speech samples into respec...
