Tibetan-Chinese speech synthesis method and device

The invention provides a Tibetan-Chinese speech synthesis method and device and aims to synthesize input Chinese or Tibetan statements to be synthesized, through a Chinese-Tibetan hybrid corpus preliminarily established. Chinese or Tibetan speeches can be synthesized at the same time by the method and the device. Compared with a traditional HMM-based (hidden Markov model based) speech synthesis system, the method and the device have the advantages that a speaker adaptive training process is added to a training phase to acquire a Chinese-Tibetan hybrid speech average model, the influence caused by speaker differences in a speech library can be reduced through the speaker adaptive training process, and quality of synthesized speeches is improved; on the basis of the average model, and a Tibetan or Chinese speech excellent in both naturalness and fluency can be obtained through synthesis of few Tibetan or Chinese corpus data through a speaker adaptive conversion algorithm; the research is significant to promoting the development of communication with minorities and the development of minority speech technologies.
