| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The purpose of this study was to conduct end-to-end text-to-speech synthesis in Japanese; we developed a system that uses Japanese kana characters and prosodic symbols as input for text-to-speech synthesis of the encoder-decoder model. Full-context phoneme labels are currently used for learning data in our system of statistical parametric speech synthesis, which uses a deep neural network (DNN) operating on broadcasting content. The data are composed of phonemes, phoneme boundary positions, accents, and accent phrases and are calculated automatically by executing language processing and forced alignment. The problem with this method is the high cost of manual correction for high-quality text-to-speech synthesis. In contrast, the proposed method does not prepare phoneme boundary positions. It was found that the workload of correcting the phoneme boundary position, which is particularly expensive, could be omitted. Japanese kana characters and prosodic symbols are simple description methods for representing speech. Hence, it is possible to directly compose kana and prosody and to arrange data without preparing dedicated software. In this study, we employed Japanese kana characters and prosodic symbols as the input method for text-to-speech synthesis by learning the encoder-decoder model. Subjective evaluation experiments indicated that Japanese text-to-speech results were equivalent in quality to those of synthesis using the acoustic features of the original speech. | |
