  　设计了一种以PIC16F877单片机作为控制核心的录放音智能语音系统, 采用ISD4003 - 8M设计制作了具有定时录音、 放音的语音提示器, 可以真实的再现语音的真实自然效果, 避免了一般语音电路因为量化和压缩所造成的量化噪声和失真。该系统 操作简单, 可靠性高, 成本低, 可广泛用于各种对安放要求较高的场合。(Design a single chip microcomputer as the core to control the PIC16F877 recording sound intelligent voice system, adopting ISD4003-8 M design a timing recording, Let the sound of speech cuing component, can be true of representation of the true nature of speech effect, to avoid the general voice circuits for quantitative and compressed by the quantization noise and distortion. The system Simple operation, high reliability, low cost, can be widely used in all kinds of higher requirements to put the occasion. )
