摘要:在智能仪器仪表或自动控制设备中，增加语音功能极大的提高人机界面的友好性，方便用户操作。在许多场合，设计者需要将语音系统和单片机结合在一起，解决上述问题。目前，语音合成、语音识别、语音存储和回放技术的应用越来越广泛，尽管利用一般的单片机测控系统中都有的硬件电路（如A/D、 D/A、存储器等）能完成语音信号的数字化处理，但是功能比较单一、且效果不是很好。本文采用单片机AT89S52与语音芯片ISD2560组成的语音存储系统，实现了语音的录取、循环回放。系统硬件电路简单，调试方便，性价比高，实用性强。

Abstract：In the smart instrumentation and automatic control equipment, increasing the voice features greatly improve the man-machine interface friendly, convenient user operation. On many occasions, designers need to voice system and MCU together, to solve the problem. At present, speech synthesis, speech recognition, voice storage and playback technology more widely, despite the use of single-chip control system have the hardware circuit called (such as A / D, D / A, memory, etc.) can complete voice digital signal processing, but a single function, and the effect is not very good. This paper uses single-chip AT89S52and voice chip ISD2560speech consists of storage system, Implementation of voice admission, the loop playback. The system hardware circuit is simple, convenient adjustment, high performance-price ratio, Practical.
