基于拼音输入的语音合成器的设计和实现

The Design and Implementation of Voice Synthesizer based on Pinyin Input Method

设计了基于拼音输入的语音合成器的总体方案,该方案用C语言编程,以STC89C52单片机作为中心控制器,利用国标码的编码特性,选用高效的数据结构,在尽可能减少拼音输入法所占代码空间的情况下,结合矩阵键盘与带中文字库的LCD液晶显示屏实现中文拼音输入法。按照所设计的拼音输入法操作流程,通过键盘输入文本,在液晶显示屏上显示,利用语音合成技术,文本数据通过语音合成模块的处理,转换为语音,经过功放与喇叭输出,实现硬件的自然语调发声。

The overall scheme of the voice synthesizer based on Pinyin input method is designed. The sys- tem controlled by STC89C52 is programmed by C. Efficient data structure is applied by taking the advantage of coding character of GB code. The code space is decreased while Pinyin input method, based on Squared keyboard and LCD attached by Chinese font, is implemented. According to the designed flow of Pinyin input method, text is iaput through keyhoard and displayed on LCD. The text is then transformed into speech by speech synthesis module and the speech is output through power amplifier and loudspeaker, realizing acoustical generating on the hardware.
