摘要：In this paper the concept of Hidden Markov Model has beenimplemented and tested in noiseless environment for speechcommand recognition (speaker dependent) and convert a machineinto intelligent machine which is responding to human speech andactivating the operating system commands. Preprocessing, FeatureExtraction and Recognition these three steps of Hidden MarkovModel are used to complete this Automatic Speech RecognitionSystem. Endpoint detection, Framing and Windowing of thespeech signal include in frst step preprocessing. Linear PredictiveCoeffcients, Cepstral analysis, Vector quantization includes insecond step Feature Extraction and HMM based classifer usedin last step Speech Command Recognition.
