20 Claims

1. In a computer system that implements a speech decoder, a method comprising:

receiving encoded data as part of a bitstream;

decoding the encoded data to reconstruct speech by performing operations comprising:

decoding residual values, including:

decoding a set of phase values, including reconstructing at least some of the set of phase values using a weighted sum of basis functions; and

reconstructing the residual values based at least in part on the set of phase values; and

filtering the residual values according to linear prediction coefficients; and

storing the reconstructed speech for output.
