傣语是傣族人民使用的语言,目前仅在中国云南就有近120万人口使用。研究傣语语音合成对推进傣语信息化具有重要意义。本文以开发应用系统为目标,研究了基于HMM框架的傣语语音合成系统的实现方法,并详细阐述了语料收集与挑选、录音、文本归一化、自动分词、文本罗马化与标注、上下文属性与问题集设计、HMM训练以及产生合成语音等模块的实现方法。实验结果表明,采用本文的合成方法,其合成语音有较好的可懂度,而其自然度还有待进一步提高。
Dai language is the language used by the Dai people. Currently, there are nearly 1.2 million people in Yunnan alone. It is of great significance to study the phonetic synthesis of Dai language to advance the informatization of Dai language. In this paper, the development of application system as the goal, this paper studies the realization of the Dai language speech synthesis system based on HMM framework, and elaborates the corpus collection and selection, recording, text normalization, automatic segmentation, text romanization and annotation, contextual attributes And problem set design, HMM training, and the realization of synthetic speech module. Experimental results show that, using the synthesis method in this paper, the synthetic speech has better intelligibility, but its natural degree needs to be further improved.
