Speechformer: Reducing Information Loss in Direct Speech Translation (2021.emnlp-main)
Copied to clipboard
| Challenge: | Current approaches to speech-to-text translation (ST) use a pipeline of two sub-components - an automatic speech recognition (ASR) and a machine translation (MT) model. |
| Approach: | They propose an architecture that avoids initial lossy compression and aggregates information only at a higher level according to more informed linguistic criteria. |
| Outcome: | The proposed architecture achieves gains of up to 0.8 BLEU on the standard MuST-C corpus and up to 4.0 BLUE in a low resource scenario. |
