The speech processing and its application to intelligent system is the state of the art research. The systems are getting smarter day by day with the introduction of the speech signal to control the machine. The basic model of human speech system is used to design the algorithm which is able to detect words as well as an alphabetical letter to generate commands and control machine. The speech enhancement followed by feature extraction algorithm is used to extract the information embedded in speech signal. Once the speech is enhanced and the valued information is extracted, automatic speech recognition system is used to continuously detect the environmental sound and capture the portion of sound which is in the range of human speech frequency. Feature classification algorithm is further used to detect words or letter following different class.
