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 peo
