Artificial intelligence speech news is a kind of speech news realized by artificial intelligence technology, and it is an innovative way of traditional news. This paper constructs an intelligent news communication system with speech processing technology. By deploying a keyword wake-up system based on neural network algorithm on a single chip computer, it completes the transformation from the recognition of keywords in isolated fragments in the training algorithm to the recognition of keywords contained in continuous speech in the actual deployment scene. Through the analysis of the experimental results, we can know that the accuracy of conventional news broadcast using artificial intelligence broadcast system is higher than that of ordinary manual broadcast, and the accuracy of broadcast is close to 100%. Moreover, compared with the traditional manual broadcasting mode, the artificial intelligence broadcasting system can effectively speed up by more than 50%. Therefore, this paper provides a reference for the follow-up intelligent communication of speech news.
