| Summary: | 碩士 === 國立中央大學 === 電機工程研究所 === 98 === This thesis deals with the design of an interactive speech guidance system for Dasi and Longtan. We use a hierarchical structure for keyword spotting to improve the recognition capability of the system. Through a series of questions and answers, a user-friendly interface is established. The developed speech guidance system provides interesting information for Dasi and Longtan, including the geographical names, some famous persons, industries, scenic spots and so on.
In our experiments, over 800 utterances pronounced by 8 males and 8 females are used to test the system performance. In average 0.25 seconds is spent for identifying a keyword and a recognition rate of 95.7% is obtained for the developed speech guidance system.
