摘　　要：采用ISD2560语言芯片和AT89C52单片机设计应用于汽车电子桩考仪中的语音系统.介绍了汽车电子桩考仪和ISD2560芯片的特点,根据芯片特点和所需实现的功能进行软硬件设计并给出了系统的硬件电路以及录、放音使用的源程序,实现语音提示的分段录音、循环及组合播放.现场实际应用表明,与其他语音电路比较,本系统具有电路简便、软件编程方便灵活、集成度高、使用方便等特点.In the paper,a sound system is developed based on AT89C2051 and ISD2560 for automobile stake test. The main function of the system is to record the voice part by part and play back in sequence or combination. The requirements and characteristics of automobile stake test system and chipset ISD2560 are also introduced in the paper. Based on the requirements of the test system, the hardware circuit and software are designed with source programs presented. Tested by the experiment, the sound system is featured as simple hardware circuit, flexibly programmed software, high integration and convenient for using when compared with other sounding systems.
