Title       Voice broadcast based on WT588D voice chip         

Abstract

With the continuous progress of human society, with the popularity of voice chips, Voice broadcast device is more and more applied in the station,taxis and other public places,and facing the development direction of family personal use, more humane. With the wide application of electronic technology, and its increasingly high degree of automation, the use of more and more widely. Meanwhile, with the large-scale development of voice processing integrated circuits, in the traditional areas of control, the application of voice prompts more and more widely.

WT588D is a voice chip with a microcontroller core, therefore, can be branded as WT588D series voice microcontrollers. Multi-function, good sound quality, stable performance and wide application is WT588D series voice chip’s talent, it to make up for the past various types of defects in narrow application areas. WT588D series voice chip support SPI - FLASH content online download, this is an application personnel indispensable advantage! 

This article designs voice prompt system based on WT588D voice chip, analyzes systematic software and hardware, and introduce the structure of WT588D voice single chip, its functions and working mode. By the control of AT89C2051 single chip, voice broadcasting can be realized. After the amplified audio output for audio processing, audio amplification to the speakers for playback.
