Zero-Shot Text-to-Speech for Vietnamese

This paper introduces PhoAudiobook, a newly curated dataset comprising 941 hours of highquality audio for Vietnamese text-to-speech.Using PhoAudiobook, we conduct experiments on three leading zero-shot TTS models: VALL-E, VoiceCraft, and XTTS-V2.Our findings demonstrate that PhoAudiobook consistently enhances model performance across various metrics.Moreover, VALL-E and VoiceCraft exhibit superior performance in synthesizing short sentences, highlighting their robustness in handling diverse linguistic contexts.We publicly release PhoAudiobook to facilitate further research and development in Vietnamese textto-speech.
