Description: This paper first introduces the research and development of speech recognition, and then follow the process of the speech recognition system, describes the various steps of the speech recognition, several methods are available and each step were analyzed and compared on an experimental basis. Study of the speech signal preprocessing and characterized parameter extraction, including voice signals of the digitization, stars frame windowed pre heavier filtering, endpoint detection timely domain feature vectors and transform domain feature vector. Wherein the endpoint detection using double doors limit law. By experiment than the characteristic parameters of the selected 12 order linear prediction cepstral coefficients as recognition parameters. A detailed analysis of a specific isolated word recognition
