| 摘 要： | 英文文语转换系统中的韵律生成模块和多音词消歧模块均必须用到单词的词性信息，因而词性标注是英文TTS系统中一个非常重要的部分。讨论了在只有一个词库的有限条件下，如何通过决策树中的C4.5算法进行词性标注的非监督学习，同时讨论了未登录词的词性猜测问题。

| Abstract: | Part-of-Speech is essential for prosody generation module and homograph disambiguation module in English TTS(text to speech) system. An unsupervised learning of part-of-speech tagging using decision trees was described, under the condition of a lexicon. In addition, the problem of unknown word guessing was also discussed. |
