基于单片机的语音采集系统的设计(任务书,开题报告,外文翻译,论文11000字)
摘 要
随着科技的发展，最近几年语音采集以及识别技术取得了很大的进步，随着技术的进步，语音技术也正慢慢从实验这个阶段走向应用于生活这个阶段。语音采集系统是语音技术的一个重要组成部分，也因此慢慢成为社会生活和人类的发展所必不可少的一部分。所以基于单片机的语音采集系统会有着较高的实用价值。
本论文详细介绍了整个设计的方案，并且分几个模块详细介绍了基于单片机的语音采集系统的一些基本功能以及其工作原理。本方案的核心单片机是凌阳生产的SPCE061A单片机，它的外围电路是：驻极体麦克风语音采集模块，小型扬声器语音播放提示模块，LED显示模块，电源模块，复位模块。语音信号被采集到后，通过单片机的储存，对比处理之后，由语音提示以及LED来展示采集后的结果。本论文详细分析了各个模块的组成以及作用，并对软硬件的设计做出详细的分析。
通过测试，确定本设计的各个模块的功能均已达到本设计的所有要求。

The speech acquisition system based on SCM
ABSTRACT
In recent years, in the wake of developments in science and technology, brilliant progress has been made in the technology of speech acquisition and recognition. Because of the progress, speech technology gradually takes its place on daily life instead of in the laboratory. Speech acquisition system is an important part of speech technology and it also gradually becomes an indispensable part of social life and human development. Therefore, the speech acquisition system based on SCM will has higher practical value.
In this essay, the plan of the whole design will be explicitly introduced. The essay has been divided into several modules to introduce some basic functions and work principles of the speech acquisition system based on SCM. The key SCM in the plan is SPCE061A produced by Ling Yang Corporation. Here are its peripheral circuits: the module of electret microphone speech acquisition the module of small loudspeaker voice prompting the module of LED display the module of power source the module of reset. The result will be displayed by voice prompt and LED through single chip storage after the speech signal has been acquired and the comparison of treatment has been made. In this essay, the organization and function of each module and the design of soft hardware will be explicitly analyzed.
It is sure that the function of each module has all met the requirements in this design.
Keywords: SPCE061A; audio capturing; voice recognition; speech processing
