CHINESE LANGUAGE TONE CLASSIFICATION APPARATUS FOR CHINESE AND F0 GENERATING DEVICE FOR CHINESE

摘要

PPROBLEM TO BE SOLVED: To make it easier to determine tones in Chinese speech. PSOLUTION: A Chinese language tone classification apparatus 110 includes: a tone model 106 trained to output probabilities of tone classification. The anchor based tone discriminating features include onset gap and offset gap, and preferably, an F0 slope coefficient. The apparatus 110 further includes: phonetic segmentation module 150 for segmenting a Chinese speech 108 into a series of tone nuclei; feature extraction module 152 and anchoring feature extraction module 154 for extracting anchor based tone discriminating features; and a pattern matching module 156 that outputs the tone classification that achieves the highest probability.
