The Application And Research Based On DSP Speech Process System

With the progress of modern computer technology, computer is used by People more than past time. Because communicating through speech with computer is the most comfortable way, the speech technology became a mark of the development of science. Speech recognition and synthesis become one of the important research-field.The technology of the speech recognition process contains of more different field. The development of these-field has made contribution for the speech recognition. Nowadays, most speech recognition system is still in their infancy and has problems if migrated from lab, and much far from practicality. The ultimate reasons for restricting practicality can be classified to two kinds, precision for recognition and complexity of the system. This paper is just researching for the theory and technology problems which practicality of some problems of speech process, and also validates some part of them with experiments.Speech recognition process can be thought of not only as an process in which machine extracts character symbols from the speech signal, but also an interdisciplinary which has close relationship with automation, acoustics, linguistics, digital signal processing as well as pattern recognition etc.This paper also introduces how to design the system, in which TMS320VC5410 is used as its core circuit. In the hardware circuit TI Company's DSP is used as controller of signal collection and processor...
