基于凌阳SPCE061A单片机的语音控制小车的研究 摘 要 语音识别技术是使机器通过识别和理解把语音转变为相应的文本或命令的技术。语音识别是一门交叉学科，正逐步成为信息技术中人机接口的关键技术。目前语音识别系统按核心硬件来分主要有：以PC机为核心硬件的语音识别系统和以专用芯片为核心的语音识别系统。本课题主要阐述了一种非常适合语音处理的单片机——凌阳SPCE061A的原理，并实现了基于凌阳SPCE061A单片机的语音遥控小车。本文主要工作包括，首先介绍了语音识别基础知识以及常用的语音识别算法，然后根据嵌入式系统的特点和本课题所要求实现的具体功能，给出了基于凌阳SPCE061A单片机的语音遥控小车系统硬件和软件设计的总体方案。论文同时介绍了凌阳公司提供的集成开发环境μ’nSP IDE，利用该软件实现了程序下载和仿真调试，经调试正确的程序运行在单片机上，使用已有的语音识别算法，根据语音命令实现了小车运动方向的控制。此系统不仅具有体积小、耗电省、价格低、性能可靠的特点，还具有较快的运算速度、较高的识别率，可实现实时的语音识别。本系统的语音提示功能为人机交流提供了一个良好的界面。 关键字：语音识别，SPCE061A单片机，61开发板，仿真THE RESEARCH OF SPEECH CONTROLING CAR BASED ON SUNPLUS SCM SPCE061A ABSTRACT The speech recognition technology is a high technology, which make the machine change the speech into homologous text or order by recognition and comprehend. The speech recognition is a cross-subject, and it is becoming the key-technology of human-computer interface in information technology. At present, according to the difference of hardware core, the speech recognition system includes: the speech recognition system using PC as its hareware core and the speech recognition system using special chip. The article introduces a microcontroller which fits to processing speech--SUNPLUS SPCE061A microchip and its principle, achieve the speech controling car based on SPCE061A. The article main work includes: firstly, introduces the fundamental knowledge of speech recognition and several speech recognition algorithms, then give the hardware and software design of the speech controling car based on the SPCE061A system according to the characteristics of the embedded system and the particular requirements of the project. Then, the article also introduces the software tool called μ’nSP IDE from SUNPLUS. By using the software we can download the program to the SPCE061A and debug programs. Finally, we use the SUNPLUS’ speech recognition algorithms, the car movement direction can be controlled according to the speech command. The Speech Recognition System not only has small size, economic
