1、 I 基于单片机的语音控制小车设计 摘要摘要 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

2、， 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 II Voice control car design based on single chip microcomputer Abstract With the development of the electronics industry, the voice - the c
