摘要人类最常用的交流工具就是语言，这是我们最自然最可靠的交流方式，如果使用语音来进行人机交流，或者使用无线传输，用麦克风捕获信号，转化为电信号，从而实现在千里之外进行对机器或系统的操纵，这就是我们说的语音识别。语音识别是实现人机交互通信的一种便捷的技术手段，目前在商务办公、电信、制造业等领域，由于可以提高办公效率、降低劳动成本，因而有着十分广泛的应用，而且随着市场的需求，语音识别系统的应用将更加广泛。随着大规模集成电路技术的发展，利用单片机控制语音芯片来实现语音识别及功能实现，因其具有经济、快捷等特点，已经成为现在主流的应用方案，而本文就是采用这种方案进行设计的。61566
本文基于单片机，另外采用ICRoute公司的性能优异的LD3320语音识别芯片和相关控制电路，从而设了基于语音识别的无线遥控系统，并应用于无线遥控的玩具小车上。其中，无线模块可以使用nRF24L01。由于LD3320芯片集成了语音识别处理器和外部电路，包括AD和DA转换器、麦克风、声音输出等接口，无需外接辅助芯片，如flash，ram等。现有的产品集成可实现语音识别，人机对话等功能。识别的关键词语是可以根据我们的需要任意编辑的，所以满足了小体积，小功耗和通用的需求。所以系统有很好的应用前景。

Title Development of intelligence control system based on speech recognition
Abstract The mostly used communication tool of human is the language, which is the most natural and reliable means for communications, using voice to realize the man-machine communications, or wireless transmission captured by a microphone signal into an electric signalin the scale of thousands miles away. This is so-called speech recognition.Voice recognition is a convenient mean to achieve human-computer interaction in the official business, telecommunications, manufacturing and other related fields, which can improve office efficiency , reduce labor costs, and thus has a wide range of applications, and the needs of the market. The application of speech recognition system will be more extensive. With the development of large-scale integrated circuit technology, the use of single-voice chip voice recognition and functions because of its economic, efficient value and so on, has become thepredominant applications and had been used in this project design .
In this paper, starting from the embedded micro-processor LD3320 of the ICRoute campany of speech recognition chip and control circuit, in order to design a wireless remote control system based on speech recognition, wireless module nRF24L01. LD3320 chip integrated voice recognition processor and an external circuit, including AD and DA converters, microphone. Sound output interface, no external auxiliary chip. Flash, ram. Integrated in existing speech recognition, human-computer dialogue, identify key words can be realized according to our needs any editing, so to meet the needs of small size, power consumption, and general. This system has a good prospect of application.
