In view of the problems existing in the application of artificial intelligence technology in voice news broadcasting, the practice analysis of automatic voice broadcasting technology based on artificial intelligence technology is carried out. The process of artificial intelligence voice broadcast is analyzed, and three levels of front-end receiving, intermediate processing and results output are discussed; the system architecture and logical structure are designed; the main function, card reading function and voice broadcast function are used to simulate the operation process of the system. The results show that the system has a good ability of language recognition and preparation for broadcasting, the accuracy of conventional news broadcasting can reach 95%, and the efficiency of text interpretation is improved by about 56% compared with the traditional manual broadcasting, which greatly reduces the cost and error rate of voice broadcasting. The analysis provides a reference for the optimization and upgrading of intelligent voice broadcasting technology.
