An Efficient Spectral Envelope Quantization Using Modified Line Spectrum Frequency Pair Representation
Won Cheol Lee, Myung-Jin Bae · Information Sciences, Signal Processing and their Applications · 1996
This paper introduces a new type of representation of the line spectrum pairs as a promising alternative used for transmitting the LPC parameters. Major contribution in this paper is that the vocal track information embedded on the spectral envelope can be represented in terms of the reduced number of LSF compared to the conventional without causing any major spectral distortion.
