为实现对沪语语音的识别和与家居机器人沪语语音交互,通过分析了沪语语言的语音、语调、语法特点,提出了沪语语音的识别基元的建模方法.该方法生成了新的声韵集作为识别基元,并建立了课题相关的沪语语音语料库,同时基于HTK初步构造了沪语语音的声学模型和3-Gramm语言模型.该系统模型在家居服务机器人中得到初步的应用,系统采用VC6.0实现,实现了用现场语音对家居服务机器人动作的控制,稳定环境下实验成功率达到87.33%.语音交互实验结果表明了该系统的有效性.%To achieve Hu language speech recognition and interact with housekeeping robot using Hu language, the characteristics of phonetics, tone and grammar of Hu language are analyzed, the new method to model the basic phone units of Hu language is advanced,the new initial/final sets is generated as the basic phone sets by the method. And the corpus of Hu language speech which is related to our project is constructed. Based on HTK, the acoustic model is built and the 3-Gramm language model is initally constructed for Hu language.Hu language speech recognition system model is used in the housekeeping service robot. The system is realized with VC6.0, and controlling the action of a housekeeping service robot is realized by present speech. In the stabilizing environment the experiment accuracy can reach 87.33％. The feasibility of the proposed system are demonstrated by the voice interaction experiment.
