摘要:以单片机为核心,通过AGC电路收集语音模拟信号,转换为数字信号后存入单片机当中,再通过单片机程序实现对信号的回放。数字化语音存储及回放系统实现了对语音录音与放音的数字化控制,增加语音的存储量,对采集的语音采用了非失真压缩算法,压缩后再进行存储处理,确保了语音回放的可靠质量。
The single-chip microcomputer is used as the core,and the voice analog signals are collected through the AGC circuit,converted into digital signals and stored in the single-chip microcomputer,and then the signal playback is realized by the single-chip computer program.The digital voice storage and playback system realizes the digital control of voice recording and playback,increases the amount of voice storage,uses a non-distortion compression algorithm for the collected voice,and compresses it for storage processing to ensure the reliable quality of voice playback.
