Findings of the IWSLT 2022 Evaluation Campaign
Summary
This paper is the official report on the shared tasks run before IWSLT 2022, the main yearly venue for spoken language translation research. The campaign had eight tasks: simultaneous, offline, speech-to-speech, low-resource, multilingual, dialect, formality-controlled and isometric speech translation. Together they drew 27 academic and industry teams. For each task, the organizers describe the goals, the released training and test data, the evaluation metrics, the submitted systems and the results.
Several tasks were new or substantially redesigned. English-to-German speech-to-speech translation appeared for the first time. The simultaneous track added Mandarin as a target and fed text systems with streaming ASR output instead of gold transcripts. Experimental human evaluation was also introduced, including an MQM-based assessment for English–Japanese.
The isometric task tested length-matched translation in a dubbing scenario. It showed that ordinary MT quality scores miss whether a translation allows a natural speaking rate. The report thus serves as a reference point for comparing approaches across many SLT settings, including low-resource and dialectal speech.
Key points
- 27 teams took part. The simultaneous task drew 7 teams, its highest number so far, covering English→German, Japanese and Mandarin.
- Simultaneous systems were submitted as Docker images and scored with SimulEval. They were ranked by BLEU within low, medium and high latency regimes defined by AL thresholds on MuST-C tst-COMMON (1000/2000/4000 for English–German).
- Low-resource and dialect tasks covered Tamasheq→French and Tunisian Arabic→English. The Tunisian task had three data conditions, including the use of Modern Standard Arabic data.
- Formality control covered English→German, Spanish, Hindi, Japanese, Italian and Russian. Italian and Russian were zero-shot, with no formality-annotated training data.
- In the isometric English→French/German/Spanish dubbing evaluation, STRONG BASELINE ranked best. Smoothness and LC metrics explained why rankings differed from MT-only human judgments.
