针对韵律间断的层次性,提出了一种层次韵律间断分类方法。该方法能够充分利用韵律结构层次性,同时又能够充分利用来自声学、词典以及语法方面的特征,对不同类型的韵律间断进行分类。通过在具有韵律标注库ASCCD上的实验,该算法在综合测试集上达到平均78.25%检测正确率。
According to the hierarchical structure of prosodic break, this paper proposed a hierarchical prosodic break classification method. The method could make use of the property of prosodic break structure, and utilized the acoustic, lexical and syntactical features to classify different prosodic break. Through the experiments on the prosodic annotated corpus ASC- CD,the proposed method can achieve 78.25% correct rate on testing set.
