PCT No. PCT/JP96/02254 Sec. 371 Date Mar. 11, 1997 Sec. 102(e) Date Mar. 11, 1997 PCT Filed Aug. 8, 1996 PCT Pub. No. WO97/07498 PCT Pub. Date Feb. 27, 1997The present invention relates to a speech processing device equipped with both a speech coding/decoding function and a speech recognition function, and is aimed at providing a speech processing device equipped with both a speech coding/decoding function and a speech recognition function by using a small amount of memory. The speech processing device of the present invention includes a speech analysis unit for obtaining analysis results by analyzing input speech, a codebook for storing quantization parameters and quantization codes indicating the quantization parameters, a quantizing unit for selecting the quantization parameters and the quantization codes corresponding to the analysis results from the codebook and for outputting selected quantization parameters and selected quantization codes, a coding unit for outputting encoded codes of the input speech including the selected quantization codes, a speech dictionary for storing registered data which represent speech patterns by using the codebook, and a matching unit for obtaining the speech patterns corresponding to the input speech by using one of the analysis results, the selected quantization parameters, and the selected quantization codes. |
