Abstract: In order to make the people find the appointed places more convenient in the unfamiliar environment, an intelligent guide system based on voice interaction in public places was designed and realized. First, according to the layout of the places, the shortest path could be gotten by Dijkstra algorithm. Then, the system could extract the feature of speech combine with the principle of speech recognition system, and match template based on Dynamic Time Warping algorithm. Finally, the people to arrive at the designated places could be guided by voice interaction. The system software and interface by MATLAB was operated, based on the actual tests, the designed system could be more intuitive and quick to implement the map navigation with speech interactive mode, and the voice recognition rate 87.75%.
