摘要: 在本论文中,我们对交通大学语音实验室以前开发的台语文句翻语音系统做了如下的改进,首先,为了避免台文表示法紊乱所造成文句分析上的困难,建置了一个国语对照台文拼音的辞典,使得此系统具备了处理国语文章的‘翻译’能力;其次,为了兼顾系统日后的扩充性对断词规则作了改造,并加入数词的构词法则;接着,利用相关函数的方法求出训练语料的基频标记,藉着这些基频标记抽取更准确、有效的韵律讯息,并重新改造RNN韵律讯息产生器之架构,调整输入参数,以改进RNN韵律讯息产生器之训练,产生更接近自然语音流畅的韵律讯息;最后,将上述的作法和之前的系统介面整合。
In this thesis, an improvement of the TTS system, developed previously in the Speech Processing Lab of NCTU, on the following aspects is presented. Firstly, a “Chinese-to-Taiwanese” lexicon is built to solve the out-of-vocabulary problem of text analysis using Taiwanese lexicons only. It also makes the system possess the capability of processing Chinese text. Secondly, several rules of constructing compound words are added. Thirdly, a correlation-based pitch mark detection is employed to provide more accurate pitch information for the training of the RNN prosody synthesizer. Fourthly, the structure of RNN prosody synthesizer is changed. It uses one RNN with different input features for the generation of each type of prosodic information. Lastly, a new prototype Taiwanese TTS system is implemented on the PC with Windows 98/NT.
