摘　　要：采用汉字语音库法,将压缩后的1220个不同读音的语音数据及2个索引表存储于一片512kB的Flash存储器中,实现了基于SPCE061A的嵌入式通用汉字文本语音播放系统。阐述了系统的硬件原理和软件流程。本系统硬件结构简单,成本低廉;软件有汉字语音资源地址的计算、文本语音播放及语音播放操作与其他操作的配合等关键算法。系统采用环形缓冲区很好地解决了文本播放与输入间的配合问题,播放语音流畅、清晰。The system realizes a universal Chinese text broadcasting system which is based on SPCE061A by means of Chinese character＇ s speech library, with 1220 different compressed speech data files and two index lists being stored in a 512KB Flash. The hardware principle and software flow chart are described in detail. The hardware structure is simple and cost-efficient. The key algorithms for software include： calculation of Chinese character speech resource address, broadcasting of Chinese text and cooperation between broadcasting operation and other operations. The system adopts the circular buffer to make broadcasting operation and other operations cooperate well. The experiment proved that the system could broadcast Chinese text fluently.
