Papers with E2E-ST
Non-Parametric Domain Adaptation for End-to-End Speech Translation (2022.emnlp-main)
Copied to clipboard
| Challenge: | End-to-end speech translation (E2E-ST) systems have received increasing attention due to its less error propagation, lower latency and fewer parameters. |
| Approach: | They propose a non-parametric method that leverages in-domain text translation corpus to achieve domain adaptation for E2E-ST systems. |
| Outcome: | The proposed method outperforms the existing in-domain fine-tuning strategies on the Europarl-ST benchmark. |
Source and Target Bidirectional Knowledge Distillation for End-to-end Speech Translation (2021.naacl-main)
Copied to clipboard
| Challenge: | End-to-end speech translation models can be trained to leverage source text . however, since the input modalities are different, it is difficult to leverage the source text successfully. |
| Approach: | They propose to leverage source transcriptions via pre-training and joint training with ASR and NMT tasks. |
| Outcome: | The proposed model predicts paraphrased transcriptions as an auxiliary task with a single decoder. |
FCGCL: Fine- and Coarse-Granularity Contrastive Learning for Speech Translation (2022.findings-emnlp)
Copied to clipboard
| Challenge: | Existing methods to perform implicit knowledge transfer from machine translation to ST model are difficult because of the task complexity and data scarcity. |
| Approach: | They recommend a method which conducts explicit knowledge transfer from MT to ST model by fine and coarse granularity contrastive learning. |
| Outcome: | The proposed method improves the performance of the end-to-end speech translation model on all 8 languages. |
