基于HTK实时中文语音路名查询系统的设计和实现

HTK是英国剑桥大学开发的一个用于创建和处理隐马尔可夫模型的实验工具包,由一整套基于C语言的库函数组成。由于其在语音识别方面处于相对领先地位,且源代码公开便于系统开发调试,所以是进行语音识别研究的一个理想平台。本文介绍了HTK语音识别系统处理流程,提出了基于HTK的实时中文语音路名查询系统的设计和实现,可实现用户实时中文语音输入路名的情况下,系统将识别结果以汉字方式显示在屏幕上。本系统小巧快速,且具有较高的识别率。

Design and implementation of a chinese speech road inquiry system based on HTK

The hidden markov model toolkit(HTK)which consists of a set of library modules and tools available in C source form is a toolkit for building and manipulating hidden Markov models,developed by Cambridge University.It is an ideal platform for speech recognition research as it is at a relatively leading status and free to download for further development.HTK basic processing stages are discussed in this paper and the design and implementation of Chinese speech road inquiry system based on HTK is introduced.The system can recognize real-time mandarin speech input about road names and display the results on the screen in Chinese characters.This system which is simple and efficient meets high experimental requirements.
