Abstract
The authors have developed a signal-dependent representation which captures, with a few KL vectors and transform coefficients, the perceptually and phonetically important structure of the spectral envelope. Together with a mixed excitation strategy with some novel features, this representation has been applied to the analysis, synthesis and coding of speech with promising results in the 5-kb/s range
