ISD1400 系列芯片是较为常用了语音录放集成电路，一般多用于语音电话、

留言机等设备。更可于单片机实现接口，进行语音分段录放音的功能，可用于

自动报时器，汽车自动报站器等设备，如果采用具有语音处理的16 位或32 位

处理器实现同样的功能将会增大开发的周期和成本，会使本来简单的系统更加

的复杂。-ISD1400 series chips are more commonly used voice recorders integrated circuits, most are used for voice calls, voice mail and other devices. More MCU interface for voice above the sound recording function can be used to automate timekeeping device, Automatic stop devices such as, if the voice processing with 16-bit or 32-bit processors to achieve the same function will increase the development cycle and cost that would result in a more simple system of the complex.
