The Design and Implementation of HMM-based Dai Speech Synthesis

By far there are more than 1.2 million Dai compatriots using Dai language in Yunnan province, researching Dai speech synthesis has great significance in advancing the informationization of Dai. This paper focuses on the study of the implementation of Dai speech synthesis by taking the HMM speech synthesis framework and STRAIGHT synthesizer into account. The methods of collection and selection of Dai text corpus, recording of speech corpus, text normalization, segmentation, Romanization and the implementation of acoustic model training are described in detail. The experimental results demonstrate that the proposed text analysis and processing method can achieve the requirements of speech synthesis, the synthetic speech has good intelligibility, and the naturalness needs to be further improved.
