Abstract
A fast vector-sum codebook search method for low bit rate speech coding is presented. In this method, the codebook search is simplified by designing a vector-sum codebook that consists of orthonormal regular pulse basis vectors. A further simplification is achieved by adopting backward filtering. The method proposed has significantly reduced computational complexity, compared with the conventional VSELP, without producing any additional degradation in the quality of the synthesised speech
