基于LD3320的语音控制系统摘要：本系统是基于LD3320的语音控制系统，以LD3320和单片机（STC11L08XE）系统的中央处理器，构成一个独立的语音控制模块。LD3320芯片是一款“语音识别”专用芯片，由ICRoute公司设计生产。该芯片集成了语音识别处理器和一些外部电路，包括AD、DA转换器、麦克风接口、声音输出接口等。该芯片在设计上注重节能与高效，不需要外接任何的辅助芯片如Flash、RAM等，直接集成在现有的产品中即可以实现语音识别、声控、人机对话功能。并且，识别的关键词语列表是可以任意动态编辑的。关键字：语音控制系统；LD3320；STC11L08XE1ThevoicecontrolsystembasedonLD3320Abstract：ThissystemisbasedonthevoicecontrolsystemLD3320,LD3320centralprocessorandmicrocontroller(STC11L08XE)system,constituteanindependentvoicecontrolmodule.LD3320chipisa"voicerecognition"dedicatedchip,designedandmanufacturedbytheICRoutecompany.Thechipintegratesaspeechrecognitionprocessorandsomeexternalcircuits,includingAD,DAconverters,microphonejack,audiooutputinterface.Thechipemphasisonenergyconservationandefficiencyinthedesign,doesnotrequireanyexternalauxiliarychipssuchasFlash,RAM,etc.,directlyintegratedintheexistingproductsthatcanbeimplementedvoicerecognition,voicecontrol,man-machinedialoguefunction.Andidentifyalistofkeywordscanbeeditedatanydynamic.Keywords：Voicecontrolsystem;LD3320;STC11L08XEI目录第一章绪论....................................................................................................................................11.1课题背景........................................................................................................................11.2课题研究的目的及意义................................................................................................11.3.1硬件部分...............................................................................................................11.3.2软件部分..............................................................................................................2第二章系统方案设计...................................................................................................................3第三章系统硬件电路设计...........................................................................................................43.1单片机控制模块.............................................................................................................43.2语音识别模块----LD3320...........................................................................................43.2.1LD3320特点介绍.................................................................................................43.2.1LD3320模块功能介绍.........................................................................................53.3系统电源........................................................................................................................6第四章系统软件设计...................................................................................................................84.1系统整体流程图.............................................................................................................84.2流水灯设计理念............................................................................................................84.3流水灯设计方法.............................................................................................................94.4LED显示原理....................................
