Abstract

Many coding techniques have been proposed for the compression of speech signals. Speech signals are continuous signals shaped by the movement of the vocal tract. Linear predictive coefficients (LPC) and line spectral pairs (LSP) coefficients have been used to model the position of the vocal tract. Each speaker´s vocal tract uses a unique, finite set of positions to generate their voice. This paper compares of the performance of ordered and disordered codebooks which employed to measure and classify the repetition of the speech signal coefficients. An analysis and results of the efficient performance of both types of codebooks in terms of the quality of synthesised speech are also provided. Also both ordered and disordered codebooks can reduce the number of bit rate transmission around 20% in speech coding system
