Streaming Models for Joint Speech Recognition and Translation (2021.eacl-main)
Copied to clipboard
| Challenge: | Using end-to-end models for speech translation has become a focus of the ST community . cascaded models have the advantage of including automatic speech recognition output . |
| Approach: | They propose a model that condenses sound waves into translated text and integrates automatic speech recognition outputs into the models. |
| Outcome: | The proposed model is statistically similar to cascading models, but has half the number of parameters. |
Consistent Transcription and Translation of Speech (2020.tacl-1)
Copied to clipboard
| Challenge: | Existing models that translate without transcribing focus on translation quality, while transcription receives less emphasis. |
| Approach: | They propose a method to evaluate consistency and compare different approaches . they propose 'coupled inference' models that feature a coupled inference procedure can achieve strong consistency. |
| Outcome: | The proposed model is poorly suited to the joint transcription/translation task, but is strong enough to train for consistency. |

| Challenge: | Code switching (CS) is the phenomenon of interchangeably using words and phrases from different languages. |
| Approach: | They propose a new ST corpus that extends the joint transcription and translation setup. |
| Outcome: | The proposed model performs well even when no training data is used. |
