Abstract :
CELP speech coders give good performance but require considerable computational power. Earlier work showed how singular value decomposition can be used to speed up the calculations required for codebook search in the CELP. The bidiagonal decomposition proposed by the author is simpler and results in a fast algorithm with fixed running time
