In recent years, Chinese speech synthesis is a heated research aspect in the field of speech signal processing and a hotspot in the artificial intelligence. It is popularly used in many fields, which improves human -computer interaction and brings great social benefits to us.At first ,this paper briefly looks back on the development and history of speech synthesis, and points out the developmental future direction and the signification of Chinese speech synthesis, then introduces the foundational knowledge of speech signal processing which include modern phonetics and the mathematical model of speech signal producing, meanwhile introduces synthesis technologies of now appearing and the characteristic of Chinese speech. In the end, it weightily discuss exploration of theory of speech synthesis and it realize speech synthesis by using the technique of the linear predictive coding.In this paper, the author studies the speech signal process and method. The author abstracts the physical model of speech signal producing togain its mathematical model by using LPC technique, which make up with a set of periodic signal or gauss white noise to excite a fuil pole filter. At the same time, the author establishes a linear predictive model and solves the linear predictive coefficient and detects pitch period by using autocorrelation function. In the end, the paper realizes Chinese speech synthesis based on the LPC.
