出行者信息服务系统中后台语音识别系统的研究

Background Speech Recognition System in Traveler Information Service System

系统分析基于Microsoft Speech SDK的语音识别系统,首先给出语音识别系统的总体设计,其次对MicrosoftSpeech SDK的主要接口进行研究,在此基础上完成语音识别中XML语法文件的编制、Microsoft Speech SDK的语音识别算法的实现,然后得到信息服务发布系统中语音识别的工作流程及其结果,最后进行测试分析。试验表明,该系统具有一定的实用价值和研究价值。

The speech recognition system based on Microsoft Speech SDK is analyzed systematically.Firstly,the design of speech recognition system is given.What′s more,the main interface of Speech SDK is studied.On that basis,XML file is designed and the speech recognition algorithm of the system is completed.Furthermore,the process of the speech recognition in information service release system is obtained as well as its result.At last,the performance of the system is tested and analyzed.It is proved that the inquiry system is worth applying and studying.
