Abstract: The present thesis deals with the problem of efficient (in bit rate and computational complexity) quantization of Linear Prediction Coding (LPC) parameters for low bit rate speech coding.The thesis introduces a new LPC quantization technique based on the Multi-Stage Vector Quantization (MSVQ) combined with a multi-candidate M-L search.The resulting procedure is assessed by evaluating the quantization spectral distortion on a speech data-base and by evaluating the subjective speech quality of a low-rate speech coder which employs the MSVQ LPC quantization.
