Book Description
"VQ of speech Line Spectral Frequencies (LSF's) using PSVQ is also presented. A result in this work is that PSVQ, designed using the joint codebook design algorithm requires only 20 bits/frame(20 ms) for transparent coding of a 10$ sp{ rm th}$ order LSF's parameters." --

Low-Bit-Rate Predictive Coding of Speech Waveforms Based on Vector Quantization

Category : Speech processing systems

Pages : 17
Book Description
Abstract: "In this paper we describe an adaptive block transform speech coding system based on vector quantization of LPC parameters. In order to account for the power fluctuations, the speech signal is normalized to have a unit-energy prediction residual. The temporal variations in the short-term spectrum, on the other hand, are taken into account by vector quantizing the LPC parameters associated with the vector of speech samples and transmitting the codeword index. For each block, based on the codevector associated with the input vector, an optimum bit assignment map is used to quantize the transform coefficients.
Speech Coding and Synthesis

Category : Computers

Pages : 784
Book Description
Hardbound. The fields of speech coding and synthesis have developed rapidly over the last decade. Text-to-text speech systems now produce reasonable quality speech, and currently available speech coders can transmit good quality speech at below 10kb/s. This, in combination with the ever-increasing speed of microprocessors and signal processing hardware, has resulted in a large number of practical applications. These applications in turn have stimulated research, and the number of papers published on speech coding and synthesis have proliferated rapidly. Reflecting periodically on such developments have inspired the publication of this book. Topics such as the effect of cross channel errors on coded speech and the determination of a proper pitch contour for synthesized speech are included.Both readers unfamiliar with the fields of speech coding and speech synthesis as well as those already working within the areas, will find the book of interest.
