e/Line spectral pairs

Information
has gloss	eng: Line Spectral Pairs (LSP) or Line Spectral Frequencies (LSF) are used to represent Linear Prediction Coefficients (LPC) for transmission over a channel. LSPs have several properties (e.g. smaller sensitivity to quantization noise) that make them superior to direct quantization of LPCs. For this reason, LSPs are very useful in speech coding.
