基于单片机的语音控制小车设计 摘要 随着电子工业的发展，具有语音控制功能的小车越来越受到人们的青睐，在人们的日常消费生活中起着不可忽视的作用。目前，声控技术已在很多领域得到使用。 本文对语音控制功能的小车概况做了阐述。在硬件设计方面，本论文以凌阳公司的SPCE061A单片机为控制核心，以语音小车控制电路板为辅，设计小车的动作。完成了电源电路、复位电路、键盘电路、音频输入电路，音频输出电路和无线控制电路等硬件功能模块的设计。在软件方面，利用C语言进行编程，进行语音的“训练”和“识别”。设计出具有如下功能的语音声控小车:能够根据录制的语音命令来控制小车的前进，后退，左转，右转的功能。测试表明，在环境背景噪音不太大，控制者的发音清晰的前提下，语音控制小车的语音识别系统能对特定的语音指令做出智能反应，做出预想中的有限的动作。 论文首先对系统的方案进行论证，然后对各单元的软件、硬件工作原理进行了阐述，并介绍了系统的主要组成部分情况。 关键词：SPCE061A，语音识别，全桥驱动，小车 Voice control car design based on single chip microcomputer Abstract With the development of the electronics industry, the voice - the control car become more and more popular to people. And it plays an important role in people s daily life. At present, the voice - activated technology has had 2 in many fields, For example, voice - activated phone. Only if you called out the names you want and it automatically called to the telephone. This article gives a detail to the voice-activated car. In hardware design, the paper use Sunplus SPCE061A as the control of core. On the software, we use C language programming for voice trainingandrecognition. .Completedthepowercircuit,resetcircuit,keyboardcircuitry,audioinputcircuits,audiooutputcircuitandcontrolcircuitofwirelesshardwaresuchasthedesignoffunctionmodules.It has the following features: According to recorded the voice command to control the car to start, stop,turn right , and turn left. Tests have shown that background noise in the environment is not too big, the controller under the premise of clear pronunciation, voice control car voice recognition system can make intelligent response to a particular voice commands, limited, as expected. First of all, cca shut confirm the system of the program, and then describe the unit s software and hardware as well as introduce the main components of the situation.
