文字转发音单片处理器WTS701的原理及应用

Principle and application of the first single-chip text-to-speech WTS701

WTS701是华邦公司推出的内建喇叭驱动功能的“文字转发音”单芯片集成电路。该芯片将连续运算法与华邦专有的多层次储存技术相结合,从而实现了真正将“文字转发音”的完整功能。文中介绍了该芯片的原理及典型应用,给出了CygnalF120MPU与WTS701的接口电路,并根据相应的芯片指令给出了其控制软件的代码程序。

WTS701 is really a single chip on 'text-to-speech' produced by Winbond company, building-in algorithm with the company's patented multi-level storage(MLS) technology, different from other chips that 'text-to-speech' on the market at present. The principle and typical application of this chip are introduced in this article, the interface circuit of Cygnal F120 MPU and WTS701 is presented. The corresponding control software is provided.
