本文根据汉语的每个字音都是单音节和自动报时系统所用字音很少的特点,提出用计算机内存存贮语音的方法。通过程序读取软件时钟的小时数和分钟数,然后从内存中提取相应的时和分数字的读音,组成报时语句,最后经放大输出。这种字音合成方法有效,系统构成简单,所需接口器件容易解决,报时效果良好。 In this paper, according to the Chinese each pronunciation is monosyllabic and automatic timing system used in the pronunciation of a small feature, put forward the method of using computer memory to store voice. Through the program to read the software clock hours and minutes, and then from the memory to extract the corresponding time and minutes of the pronunciation, composed of time statement, and finally enlarged output. This kind of pronunciation synthesis method is effective, the system constitution is simple, the interface device needed is easy to be solved, the timing effect is good.
