This shared task will focus on the problem of developing speech transcription and translation tools for under-resourced languages. For the vast majority of the world’s languages there exist little speech-translation parallel data at the scale needed to train speech translation models. Instead, in a real-world situation we will have access to limited, disparate resources (e.g. word-level translations, speech recognition, small parallel text data, monolingual text, raw audio, etc).
This shared task invites participants to build the best speech transcription/translation system they can for transcribing and/or translating between the following language pairs:
- Tamasheq (taq) to French (fra)
- Marathi (mar) to Hindi (hin)
- Bhojpuri (bho) to Hindi (hin)
- Tunisian Arabic (aeb) to English (eng)
We will provide a list of available:
- parallel translation text corpora
- speech recognition datasets for source languages
- small speech translation datasets for the two language pairs
- monolingual textual corpora Note: (not all of the above will be available for all languages)
We allow the use of any pre-trained machine translation, speech recognition, speech synthesis, or speech translation model. We will allow both constrained and unconstrained submissions (a constrained submission will be one using only the data we provide/list). The only data that will not be allowed will be the ones that will be part of the test set.
We invite participants to explore all possible research directions: from pipeline approaches, to end-to-end models, offline or online methods, using other languages through cross-lingual transfer, which provides several datasets), data augmentation, and anything else you come up with.
We look forward to your creative submissions!
Allowed Training Data
You may use any of the resources listed below or any other resource you deem appropriate.
- Speech-to-translation parallel data: here
- Additional audio data (see description in the above Github page): here
Tunisian Arabic - English
- You can use the same data used for the dialect task (unconstrained condition).
Marathi and Bhojpuri - Hindi
- Coming January 23rd!
The primary task is translation, and hence the submissions will be evaluated using standard automatic translation metrics (e.g. COMET, BLEU and chrF++ as computed by SacreBLEU).
In addition, if the participants’ systems also produce transcriptions for the source utterances (which would be the case for pipeline/cascade or multitask systems), we will invite their submission and also evaluate on ASR quality using standard ASR metrics (WER).
Submissions should be compressed in a single .tar.gz file and emailed here (TBA), with “IWSLT 2022 Low-Resource Shared Task Submission” in the title.
We would like to see outputs for both test sets. If multiple outputs are submitted for one test set, one system must be explicitly marked as primary, or the submission with the latest timestamp will be treated as primary.
File names for translation outputs should follow the following structure:
gmu.st.primary.swa-eng.txt for translation outputs.
File names for speech recognition outputs should follow the following structure:
gmu.asr.primary.swc.txt for ASR outputs.
Submissions should consist of plaintext files with one sentence per line, following the order of the test set, pre-formatted for scoring (detokenized). We ask that the participants include a (very) short system desciption in the submission email.
