单片机语音合成系统的设计

摘要：语音合成技术是实现人机语音通信，建立一个有听说能力的口语系统所必需的关键技术之一。随着计算机运算速度的提高，人工智能领域的研究获得了飞速发展，而人工智能领域的最新研究成果不断地向语音研究渗透，促使语音处理技术及语音合成的研究也产生了突破性的飞跃。和语音识别相比，语音合成技术相对要成熟一些，是该领域中近期最有希望产生突破并形成产业化的一项技术。介绍一个以语音合成系统为主电路，在单片机89C51的管理下，用软件编程并通过串行口编程进行通信，产生不同定时来准确地控制乐曲节奏，最终实现蜂鸣器唱歌的过程。此通用合成语音系统能根据需要利用多种语音压缩算法无缝地混合配合，用以优化语音质量和存储容量。此设计使人们能够甩掉键盘，通过语音命令进行操作。系统在完成其它任务的同时具备语音输出功能，可使单片机系统成本下降，体积减小，可靠型提高。它对于解脱繁琐的事物性和危险性工作更具有意义。

Design Of SCM Speech Synthesis System Abstract：Speech synthesis technology is a human-computer voice communication, listening and speaking ability to establish an oral system one of key technologies required. With the increase in computing speed, artificial intelligence research in the field has made a rapid development, the latest in artificial intelligence research studies continue to penetrate to the voice, speech processing technology and to promote the research of speech synthesis created a breakthrough leap. And voice recognition compared to speech synthesis technology is relatively mature, is the most promising areas of recent breakthroughs in production and the formation of a technology industrialization. Describes a speech synthesis system, the main circuit, under the management of the 89C51 microcontroller, software programming and programming through the serial port to communicate, have different time to accurately control the rhythm of music, and ultimately the process of singing buzzer. The general synthetic speech systems as needed using a variety of voice compression algorithms seamlessly mixed with, to optimize voice quality and storage capacity. This design allows people to get rid of the keyboard, through voice commands to operate. System to complete other tasks at the same time with voice output, SCM systems can lower costs, reduce size, improve reliability type. It complicated things for free and dangerous work more meaningful.
