Understanding and Bridging the Modality Gap for Speech Translation (2023.acl-long)
Copied to clipboard
| Challenge: | Existing methods to improve end-to-end speech translation (ST) use multitask learning, but there is always a modality gap between ST and MT due to the differences between speech and text. |
| Approach: | They propose a method to bridge the modality gap between ST and MT by leveraging (text) machine translation data. |
| Outcome: | The proposed method bridges the modality gap and achieves significant improvements over baseline in all eight directions. |
