摘要: 在本论文中,我们在台语TTS系统中引进了变调的观念,处理先前研究中所未考虑到的变调规则,以及词性的观念,应用于TTS系统中的韵律讯息产生器与文句分析部分,让语音合成的的效果可以更自然流利。我们并针对台语词库作改进,希望对语音合成系统对文章的断词结果可以有较佳的结果,以改善语音合成的品质。我们并使用统计方法来制作一个台语的短词合成系统。
In this thesis, based on a Min-Nan speech TTS system proposed in previous study, some modifications were done to improve the quality of synthesized speech. The original Min-Nan speech TTS system contained three parts- text-parser, prosodic information generator and PSOLA synthesizer. It is well known that the tone sandhi will change the tones of most speech from the lexicon tone in Min-Nan. In order to get better pitch contour of synthesis speech, a unit is added after parser to change the tone information generated from parser according to the tone sandhi rules of Min-Nan. The POS(part of speech) is also added in the lexicon of parser to get more information in text and a better performance of prosodic information generation unit was achieved. Finally, in order to improve the performance of short word, a statistical prosodic information generating scheme is built for a word synthesizer.
