基于ISD25120的语音录放系统

A voice-recording/playing system based on ISD25120

在分析ISD语音处理器件性能的基础上,设计了在AT89C2051单片机控制下用ISD25120语音芯片实现的微电脑语音系统。与传统语音处理技术相比,该系统具有硬件电路简单、开发周期短和高保真音质的优点。工程应用表明,该系统操作方便、可靠性强、音质好,可作为电脑语音服务系统的语音板。

On the basis of analyzing the feature of the speech signal processing chip, the microcomputer speech system made of AT89C2051 and ISD25120 is designed. Compared with the traditional speech signal processing technology,the system has the advantage of simple circuit, short developing period and Hi-Fi speech. It was proved by consumers that the system could be operated easily, relied on strongly, and with excellent speech. So it can be served as sub-system in computer speech system.
