摘 要
语音处理技术是一门新兴的技术，它不仅包括语音的录制和播放，还涉及语音的压缩编码和解码，语音识别等各种处理技术。以往做这方面的设计，一般有两个途径：一种方案是单片机扩展设计，另一种就是借助于专门的语音处理芯片。采用凌阳公司的SPCE061A16位单片机作为语音控制小车的检测和控制核心，配合SPCE061A的语音特色，利用系统的语音播放和语音识别资源，通过控制I/O接口电路传输控制信息，从而控制全桥驱动电路最终实现多功能语音控制小车的基本功能。利用编程进行语音的“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启动、停止、返回、拐弯。

Abstract
Speech processing technology is a new technology, it
includes not only the voice recording and playback, and in the speech compression encoding and decoding, speech recognition and all kinds of processing technology. Before the design, generally there are two ways: a single chip design scheme is extended, and the other is by special speech processing chip.Based on the voice characteristics of MCU Sunplus SPCE061A，the small car of muhifunction voice—controlled was designed．The car system is composed of voice recognition and voice broadcast，and its transmission and controlling information is controlled by I／O interface circuit．In order to
control full bridge drive circuit at last the basic functions of
muhifunctional voice-controlled small car are realized．We use programming for voice \and \It has the following features: According to recorded the voice command to control the car to start, stop, return, and turn.
