Abstract
The present voice recognition has achieved high recognition accuracy in theory and the laboratory condition, but many speech recognition algorithms are realize on PC. A system platform with DSP core can realize real-time speech processing algorithms, and in cost, power consumption and volume has the advantages of PC did not own, and has a good application prospect. This paper emphasis on how to realize speech recognition in DSP and its whole hardware and software technological process, and analyzed the program with CCS's self-contained process analysis tools Profile. In order to improve the recognition rate, a high performance DTW algorithm which differ from the traditional DTW algorithm is used. So real-time control is achieved and obtain a high recognition rate.
