摘　　要：由于在某些场合无法手动操作相机,为此设计出基于语音识别的相机控制系统。该系统通过对语音关键词的识别,使相机完成所设定的缩放、特效变化、对比度调整、拍照等动作。提出的系统主要包含语音识别部分和照相机部分。语音识别部分主要由LD3320语音识别芯片识别语音,STC11单片机产生信号;照相机部分通过STM32嵌入式微控制器接收信号,由OV2640摄像头和液晶显示屏拍照并显示,还可以通过语音控制对照片进行特效、饱和度、对比度、缩放等处理。经实验验证表明,该系统运行稳定,能够准确地识别关键词语音,正确完成设计操作。Since the camera cannot be operated manually in some occasions,a camera control system based on voice recognition is designed for this purpose.This system allows the camera to complete the set zoom,special effect changes,contrast adjustment,photographing and other actions through recognition of voice keywords.The system mainly includes a voice recognition part and a camera part.The voice recognition part mainly recognizes the voice by the LD3320 voice recognition chip,and the STC11 microcontroller generates signals;The camera part receives the signal through the STM32 embedded microcontroller,and the OV2640 camera and LCD display take pictures and display,also use the voice control to perform special effects,saturation,contrast,zoom and other processing on the photo.The experimental verification shows that the system is stable and can accurately recognize the keyword speech and complete the design operation correctly.
