多功能语音控制小车--Z4.docVIP

智能语音遥控车设计 摘 要 自从人类可以制造和使用各种机器以来，人们就有一个理想，那就是能让各种机器能听懂人类的语音并能按人的口头命令来行动，从而实现人机交流。随着科学技术的不断发展，语音识别（Speech Recognition）技术的出现，使人类的这一理想得以实现。语音识别识别技术就是让机器通过识别和理解把语音信号转变为相应的文本或命令的高技术。语音识别是一门交叉学科，它正逐步成为信息技术中人机接口的关键技术，语音识别技术与语音合成技术的结合，使人们能够甩掉键盘，通过语音命令进行操作。语音技术的应用已成为一个具有竞争性的新兴高科技产业。当今，语音识别产品在人机交互应用中已经占到越来越大的比例。 本文在介绍了国内外嵌入式语音识别发展状况和识别的原理的基础上，阐述了一种非常适合进行嵌入式语音处理的单片机——凌阳SPCE061A单片机及其在音控小车系统中的应用。 本设计依据成本低、性能好的前提下完成以下任务： 1．选择了一款“凌阳大学计划”专门为毕业设计准备的精简开发板“61板”，在硬件上实现了语音信号的采集、语音信号的存储、语音信号处理和语音播报等功能。 2．本系统模拟将来的智能小车，根据开始录制的语音命令来控制启动、停止、返回和语音模，并且能自动进行前进和倒退。利用光电检测器来控制电动小汽车行驶轨迹。 3．本系统的语音提示功能为人机交流提供了一个良好界面，在进行语音训练的基础上可以实现特定人的语音识别和人机对话。 关键词 单片机； 语音控制； 光电寻迹 Design of Intelligent Speech Control Robot-Car Abstract Since human being can make various machines and use them, people have had an ideal that various machines could understand their language, and act according to their orally orders, thereby realizing the linguistic communion between the human and the machine. With the unceasing development of the technology, and the appearance of Speech Recognition Technology, the ideal of human being has realized. The Speech Recognition Technology is a high technology, which make the machine change the speech signals into homologous text or order by recognition and comprehend. The speech recognition is a cross-subject, and it is becoming to the key-technology of human-computer interface in information technology. The combination of speech recognition an speech synthesis make man can operate the computer through the speech order without the keyboard. The application of speech recognition has become a rising competitive high technology industry. Today, the products of speech recognition have already taken up more and more proportion in the application of human-computer interaction. On the base of introducing the development of the Embedded Speech Recognition System in domestic and overseas and the theory of speech recognition, the article introduce one Microcontroller which fit to processing speech?
