本文介绍了在微计算机Cromemco System Ⅲ上模拟电话授时台的方法及实验结果.其特点是通过语音编码压缩数据量,并利用微计算机的内部时钟,在微计算机上做到实时语音输出.实验结果表明,当用户有报时要求时,输出的语音质量是好的.由于经语音编码后压缩了数据量,所以电话授时台的工作可以利用单板机来实现.对于其它需要有限语音输出的自动化系统,本方法也有参考价值.
This paper introduces the method and experiment result of simulating telephone service station on microcomputer Cromemco System Ⅲ, which is characterized by compressing the data volume by voice coding and real-time voice output on the microcomputer by using the internal clock of microcomputer. Shows that the voice quality of the output is good when the user has the time-required output.The work of the telephone service station can be realized by the single-board machine because the data amount is compressed after being encoded by the voice.For other automation systems that require limited voice output , This method also has reference value.
