Design of voice service system for agricultural keywords recognition

To solve the problems of tedious key-press and poor interaction in current agricultural information voice service system, a method based on keywords recognition for agricultural information voice service system is proposed in this paper. It simplifies inquiry process and enhances interaction with customers by combining speech recognition and voice service system. Based on the design of modular, this system introduces an engine for speech recognition on keywords. The system consists of analog voice card, access module, process module, speech pre-processing module, speech recognition module and data module. This paper describes the implementation of these modules.
