| Abstract(in English) | For ultra very low bit speech coding as less than 100bps, we describe the method to acquire speech units automatically which have almost same time length as a syllable. Optimal speech units are obtained with the procedure that, the number of units is given beforehand and pattern of units is updated successively based on a minimum distortion criterion. At this time, a restriction is embeded that utterances spoken as the same word are expressed the same sequences of speech units, so we present algorithms for this purpose. When we acquired speech units automatically on condition both the number and length of units equivalent to syllables and used these for 216 words recognition experiment, the recognition rate was obtained higher than that of syllable-based method. And the word recognition rate about, 98% or so was achieved by increasing the number of units, while the bit rate was still less than 60bps. |
