| 摘 要： | 为了不断发展和完善我国的社区服务体系,让信息技术逐步应用于社区服务,项目组设计实现了基于HTK的社区语音接入服务平台。HTK(Hidden Markov Model Toolkit)是一个基于隐马尔可夫模型(HMMs)的语音处理工具,在语音识别领域处于国际领先水平。平台由最初的高斯单音素HMMs模型,哑音素HMMs模型经训练得到了输出分布更加稳健的三音素HMMs模型。在非特定人低噪音环境下单词识别率达到93.22%,整句识别率达到80.50%,取得了良好的识别效果。

| Abstract: | In order to continuously develop and improve China's community service system,and gradually applie the information technologies to community service,the HTK-based community service platform for voice access is typically designed and implemented.HTK is a voice processing tooles witch based on Hidden Markov Model(HMMs).And in the field of speech recognition it has reached at the advanced level in the world.The platform is implemented by triphones HMMs whitch has a robust output distribution evolved form the o... |
