Abstract(in English) | In this paper, we investigate to reduce noise of LSP parameter with Neural Networks trained by non-noise LSP parameter. We quantize a vector of LSP parameters by scalar-quantizing the output of each unit of hidden layer and we find an appropriate number of scalar quantization bits to reduce noise. We investigate performance dependency on the number of middle layer units and compare between three-layer and five-layer Neural Networks. We also investigate to reduce noise with K-L transform and compare the performance between K-L transform and Neural Networks. |
