Abstract

Many modifications can be applied to a speech signal without changing its perceptual quality. For a particular speech coder, the coding efficiency will differ for distinct modifications. To exploit this, we introduce a generalized analysis-by-synthesis procedure. In this procedure, a search is performed over a multitude of modified original signals (on a blockwise basis), and the signal which can be encoded with the least distortion is selected for transmission. At the receiver, a quantized version of this modified original signal is constructed. We discuss the application of generalized analysis-bysynthesis coding to the pitch predictor of a CELP coder. The use of this technique makes it possible to transmit the pitchpredictor parameters at a much lower rate than conventional approaches, without compromising speech quality.
