Method, Apparatus, and Speech Synthesis System for Classifying Unvoiced and Voiced Sound

摘要

A method, apparatus, and speech synthesis system are disclosed for classifying unvoiced and voiced sound. The method includes: setting an unvoiced and voiced sound classification question set; using speech training data and the unvoiced and voiced sound classification question set for training a sound classification model of a binary decision tree structure, where 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; and receiving speech test data, and using the trained sound classification model to decide whether the speech test data is unvoiced sound or voiced sound.
