微波炉语音控制系统 毕 业 论 文（设 计） 题 目： 微波炉语音控制系统 （Title）： Voice control system for microwave oven 微波炉语音控制系统 摘要 本系统是由单片机、语音识别模块、键盘、显示等的组成部分，用来模拟微波炉控制电路及其功能实现。主控部分是由单片机和语音模块部分构成，显示部分是由LCD显示模块和LED工作模拟部分构成。 微波炉控制器系统以AT89S52单片机为核心，由液晶显示模块、 语音识别电路模块、键盘模块、掉电存储模块、电源模块等功能模块组成。本系统对语音功能和定时功能进行了重点设计。此外，还设置了微波火力八级档位设定、烹调模式、语音识别、烹调预约时间设置，对微波炉的基本功能进行设计与实现。本系统把语音识别模块内嵌到微波炉中，设计出一种语音识别控制微波炉。用户只需用简单、 人性化的语音指令告诉微波炉——它要执行的任务之后它就愉快地帮主人完成系统操作。 关键词: AT89C52单片机；语音控制系统 Voice control system for microwave oven Summary The system is composed of microcomputer, a speech recognition module, keyboard, display, used to simulate microwave oven control circuit and its realization. The main control part is composed of single-chip computer and voice module, display part is composed of a LCD display module and LED analog parts. Microwave oven controller system based on AT89S52 microcontroller as the core, by the liquid crystal display module, voice recognition circuit module, keyboard module, power-down memory module, power supply module. The system is focused on the design of function sets the basic and timing functions. In addition, extend the microwave power level eight gear set, cooking mode, speech recognition, cooking appointment time setting, the basic function of the microwave oven is designed and implemented. The speech recognition module is embedded into the microwave oven, design a speech recognition control of microwave oven. After the user only need a simple, user-friendly voice instructions that tell the microwave oven - which task to perform it happy to help the master to complete the system operation.
