| Abstract(in English) | Vector quantization using a codebook has good performance in low bit-rate telephone-band speech codings, however, it has problems that consume many computations and memory storages. In this paper, we propose vector quantization using a neural-network. One of problems of this approach is how to reduce the learning error. We use the Kalman-Neuro. Training(KNT)method for quantization of LSP parameters. In experimental studies, the spectral distortion results in 1.41dB by 24-bit quantization. To evaluate of performance of this method, we apply Karhunen-Loeve transform, and obtain approximately the same distortion. |
