基于单片机的语音识别控制电压播报仪

为实现利用人的语言和听觉来完成一系列双手工作的目的，我们借助于单片机对语音进行识别处理．语音识别控制电压播报仪是基于SPCE061A单片机开发出来的语音识别控制和播报系统．它的硬件部分主要由外部降压电路、MIC输入电路、SPCE061A单片机、音频放大设备等组成，软件部分则由语音识别训练模块、语音识别模块、模数转换模块、数据处理模块、语音播报模块组成，通过对系统的初始化和识别训练使之能够对所训练的语音进行识别，进而触发一系列过程：模数转换→数据处理→语音播报电压．实验结果表明，这个系统能够准确地识别语音命令，得到测量结果．

Broadcasting the Voltage Value Via Speech Recognition and Control Based on Singlechip

Singlechip can be available to achieve the aim that human's speech and hearing were utilized to replace hands.The apparatus is used to achieve broadcast of voltage value via speech recognition and control.It is based on SPCE061A.The hardware system includes the external step-down circuit,the MIC input circuit,the SPCE061A,and the audio amplifier.The software system includes the speech recognition training module,the speech recognition module,the A/D conversion module,the data processing module,and the broadcasting module.After initializing and speech recognition training,the system will recognize the target speech,and the whole process from A/D conversion to data processing to broadcast of voltage value will be sparked off.The test result shows that the apparatus can well recognise the speech order and broadcast the voltage value.
