| 摘 要： | 音节是泰语构词和读音的基本单位,泰语音节切分对泰语词法分析、语音合成、语音识别研究具有重要意义。结合泰语音节构成特点,提出基于条件随机场(Conditional Random Fields)的泰语音节切分方法。该方法结合泰语字母类别和字母位置定义特征,采用条件随机场对泰语句子中的字母进行序列标注,实现泰语音节切分。在InterBEST 2009泰语语料的基础上,标注了泰语音节切分语料。针对该语料的实验表明,该方法能有效利用字母类别和字母位置信息实现泰语音节切分,其准确率、召回率和F值分别达到了99.115%、99.284%和99.199%。

| Abstract: | Syllable is the basic unit of word-formation and pronunciation of Thai.Thai syllable segmentation is significant to lexical analysis,speech synthesis and speech recognition.Combined with the characteristics of Thai syllables,Thai syllable segmentation method based CRFs (Conditional Random Fields) was proposed.In order to achieve Thai syllable segmentation,the algorithm not only combines the Thai alphabet categories and letter position to define features,but also employs CRFs for letters in Thai sentence to do sequence labeling.In this paper,Thai syllable segmentation corpus was marked on the basis of InterBEST 2009.Experiments for the corpus demonstrate the method can effectively achieve Thai syllable segmentation by adopting the category and location information of alphabetical letters,and the va-lues of precision,recall and F reach 99.115%,99.284% and 99.199%. |
