Document Type and Number:
WIPO Patent Application WO/2019/163848
Kind Code:
A1
Abstract:
The present invention enables conversion into speech that sounds more natural. The present invention performs learning for a target conversion function and a target identifier according to an optimal condition in which the target conversion function and the target identifier compete with each other, wherein the target conversion function converts source speech into target speech, and the target identifier identifies whether or not the converted target speech follows the same distribution as actual target speech. Also, the present invention performs learning for a source conversion function and a source identifier according to an optimal condition in which the source conversion function and the source identifier compete with each other, wherein the source conversion function converts target speech into source speech, and the source identifier identifies whether or not the converted source speech follows the same distribution as actual source speech. In addition, the present invention performs learning so that the original source speech and the source speech reconstructed from the converted target speech using the source conversion function are identical, and the original target speech and target speech reconstructed from the converted source speech using the target conversion function are identical.
