摘　　要：随着时代的发展变化,人工智能在整个互联网中逐渐普及。作为人工智能中比较成熟的技术,语音识别被广泛应用在各行各业中。在信息技术服务业和教育行业中,语音识别系统的制作为人们的知识获取提供了便利的学习方式。通过研究语音识别技术的发展现状、语音识别算法的基本原理,对比3种典型的算法,选择出最优算法,进而实现了语音识别算法在硬件上的应用。通过将micro:bit作为主板,搭配IO bit 2.0扩展板,利用语音识别模块识别关键词语,不断检测听到的语音词汇,对听到的语音块作出反应,同时MP3模块和腔体小喇叭协同配合,播放问题对应的答案,从而设计完成了具有语音识别及对话功能的智能系统。With the development and change of the era,artificial intelligence is gradually popularized in the whole internet.Automatic Speech Recognition,as one of the mature technology in the artificial intelligence industry,is widely applied to kinds of jobs.Especially in the information technology service and education work,the manufacture of speech recognition system provides convenient learning way for people who get knowledge.In this paper,we study basic situation about Automatic Speech Recognition domestic and overseas,and fundamental principle of speech recognition algorithm.By comparing three classical algorithms and selecting suitable one,researchers have completed application in hardware.The design consider micro:bit as main board and IO bit as expansion board.It uses speech recognition module recognize main terms and detect constantly sounds and letters that it hears.Meanwhile,it reacts to the words hearing.Then connecting the MP3 module and the cavity speaker,speaker will play the answer about the problem.Finally,an intelligent dialogue system is designed.
