Description: The design of speech process system is based on the DSP chip, which solve the contradiction between high performance and low cost effectively. The part of sampling circuit is composed of Digital signal processing chip, voice-frequency circuit, filtering circuit, simulation of JTAG interface. The part of software introduces the fundamental theory of speech recognition, explaining the DSP realization technology of speech recognition. The system is rich in resources and the circuit provides interfaces with analog and digital signal, and could be taken as an independent module to be used for other electronic circuits, making it convenient to expand its application.
