An intrinsically reliable and fast algorithm to compute the line spectrum pairs (LSP) in low bit rate CELP coding
André Goalic, Samir Saoudi · 2002
The code excited linear prediction coder (CELP) makes it possible to synthesize good quality speech at low bit rates. In such a case, speech quality mainly depends on spectral envelope design accuracy. Different kinds of parameters belonging to the parametrical domain (linear prediction coefficients.
