xm_transformer_unity_en-hk
Speech-to-speech translation model with two-pass decoder (UnitY) from fairseq:
- English-Hokkien
- Trained with supervised data in TED domain, and weakly supervised data in TED and Audiobook domain. See here for training details.
- Speech synthesis with facebook/unit_hifigan_HK_layer12.km2500_frame_TAT-TTS
- Project Page
