Research and implementation of the speech recognition technology based on DSP

In recent years, speech recognition is a relatively active area of research in embedded systems has been a lot of applications, making it the original manual work needed to use voice can be easily completed. The use of voice as a means of human-computer interaction for users is a very convenient, very natural way, the small device at the same time also omitted in order to reduce the volume. In this paper, a branch of speech recognition - a particular person´s voice isolated word recognition, and gives specific ways to achieve. In this paper, the realization of speech recognition functions from the main hardware components and the corresponding algorithm. Simulation results validate that the high effiency of the enhanced algorithm.
