| Abstract(in English) | In distributed speech recognition (DSR), it is recommended that the MFCC (Mel Frequency Cepstrum Coefficient) is used for speech analysis. However, LSP is widely used for quantity of characteristic in speech encoding. Therefore, it is necessary to examine performance of speech recognition when LSP is used. As a result of having compared LSP with MFCC by Aurora-2J database, a recognition rate of 80.0% are provided with multicondition, relatively becomes -42.2%. And a recognition rate of 70.5% is provided in 12 bits quantization. |
