Comparison of vector and scalar quantization techniques for LPC speech compression
Fred B. Juang, David Y. Wong · The Journal of the Acoustical Society of America · 1980
Vector and scalar quantization techniques for LPC filter coefficients are compared. Geometric comparisons are made in the coefficient space and spectral distortion comparisons are made along a number of distortion measure scales. Spectral and statistical characteristics of the quantization errors for both techniques are also examined in detail. Correlations to listening comparisons of output synthesis speech will be presented. Taped examples will also be played.
