Abstract
A technique to enhance the quality of Text-to-Speech (TTS) based Singing Voice generation is disclosed. The present invention efficiently preserves the speaker identity and improves sound quality by incorporating speaker-independent natural singing information into TTS-based Speech-to-Singing (STS). The Template-based Text-to-Singing (TTTS) system merges qualities of a singing voice generated from a TTS system with qualities of a singing voice generated from an actual voice singing the song. The qualities are represented in terms of Mel-generalized cepstrum (MGC) coefficients. In particular, low-order MGC coefficients from the TTS-based singing voice with high-order MGC coefficients from the voice of an actual singer.
