| Abstract(in English) | In this paper, speech spectrum of 32 dimensions are compressed to 2-4 dimensions using a wine-glass-type neural network to implement an identity mapping. Then, the mean spectral distortion for each number of dimensions is examined. Two types of neural network(namely three and five layers) are used. It is observed that the spectral distortion is much smaller for the five-layers neural network than for the three-layers. It is also verified that a pre-devided-lerning is effective for the five-layers neural network. The distribution of middle layer's outputs of the neural network is examined. For the case of vowel data, a cluster distribution for each vowel is well separated from each others. |
