Adaptive speech feature signal generation arrangement.

摘要

A signal processing arrangement uses a codebook of first vector quantized speech feature signals formed responsive to a large collection of speech feature signals. The codebook is altered by combining the first speech feature signals of the codebook with second speech feature signals generated responsive to later input speech patterns during normal speech processing. The first set of vector quantized feature signals are thereby adaptively modified to second speech feature signals obtained from normally processed speech patterns.
