Before revision:  Using wav2vec 2.0 for acoustic modeling, and mBART for multilingual text generation, our approach advanced the new state-of-the-art for 32 translation directions (and surpassing cascaded ST for 19 of them) on the multilingual ST benchmark CoVoST 2 (+ 4.4 BLEU on average for 13 En-X directions and + 4.3 BLEU on average for 19 X-En directions).
