Tech Papers 2022: This paper introduces a semi-supervised TTS system that trains from broadcast commentary to enable automated program production.
Abstract
Thanks to the rapid progress in deep learning technology, the text-to-speech (TTS) system we developed has achieved the same quality as human speech, enabling us to launch a fully automatic program production system known as “AI Anchor.” The TTS system needs a large amount of speech and label data, but data production costs are high and TTS speakers cannot be easily added. This paper presents a novel TTS method featuring automatic training from broadcast commentary. It uses an approach that allows for a new semi-supervised learning method using an accentual data recognition method specialized for TTS.
