METHOD, APPARATUS AND SPEECH SYNTHESIS SYSTEM FOR CLASSIFYING UNVOICED AND VOICED SOUND

摘要

A method, apparatus (400), and speech synthesis system for classifying unvoiced and voiced sound is disclosed. The method includes: setting an unvoiced and voiced sound classification question set (101); using speech training data and the unvoiced and voiced sound classification question set for training the sound classification model of a binary decision tree structure, wherein the binary decision tree structure includes non-leaf nodes and leaf nodes, the non-leaf nodes represent questions in the unvoiced and voiced sound classification question set, and the leaf nodes represent unvoiced and voiced sound classification results (102); receiving speech test data, and using the trained sound classification model to decide whether the speech test data is unvoiced sound or voiced sound (103).
