Singing Voice Synthesis (SVS) {aims} to generate singing voices {of high} fidelity and expressiveness. {Conventional SVS systems usually utilize} an acoustic model to transform a music score into acoustic features, {followed by a vocoder to reconstruct the} singing voice. It was recently shown that end-to-end modeling is effective in the fields of SVS and Text to Speech (TTS). In this work, we thus present a fully end-to-end SVS method together with a chunkwise streaming inference to address the latency issue for …
