Improving Predictive Vector Quantizers in Speech Coding Applications

چکیده
In this paper, we study the intervector correlations of some parameters often employed in speech coding. The speech parameters show a switched behavior, with high correlation for most vectors, but low intervector correlation for a few. We demonstrate that a quantization scheme that takes the switched behavior into account can outperform traditional methods.

Efficient vector quantization of LPC parameters at 24 bits/frame
Abstruct-Linear predictive coding (LPC) parameters are widely used in various speech processing applications for representing the spectral envelope information of speech. For low bit rate speech-coding applications, it is important to quantize these parameters accurately using as few bits as possible. Though the vector quantizers are more efficient than the scalar quantizers, their use for accu...

In this treatise a range of Line Spectrum Frequency (LSF) Vector Quantization (VQ) schemes were studied comparatively, which were designed for wideband speech codecs. Both predictive arrangements and memoryless schemes were investigated. Specifically, both memoryless Split Vector Quantization (SVQ) and Classified Vector Quantization (CVQ) were studied. These techniques exhibit a low complexity ...

An efficient codebook driven voiced excitation coding method producing natural sounding speech is proposed. It can be incorporated as an essential part in a complete speech coder working at low bit rates. The inter-pulse correlation of such a coding scheme is investigated and exploited using linear predictive vector quantization and finite state vector quantization (FSVQ). A new and more robust...

Quantization is the process of approximating a continuous-amplitude signal by a digital (discrete-amplitude) signal, while minimizing a given distortion measure (or error). Vector Quantizers (or VQ) h ave the property of achieving asintotically the best theoretical performance. Unfortunately, conventional optimal VQ are extremely demanding in terms of both storage and memory requirements, and i...
