Speech Recognition Based on LPCC

CHEN Wei-dong,WANG Xiao-ya,XIE Jing(The 54th Research Institute of CETC,Shijiazhuang Hebei 050081,China)  
Speech Recognition is an important preprocess in speech intelligence system or machine-translation system.A speech recognition method is proposed based on LPCC parameter in the paper.Since LPCC belongs to the cepstrum domain,it can simply separate the track impulse response from the glottal excitation signal.The system uses LPCC of the speech signal as the recognized character,along with the K-mean VQ method for clustering to get the initiative codebooks.Experimental results show that different recognizing frame lengths result in different recognizing ratios.
