### Dataset Summary

This dataset is a selection of text only (English-Spanish) from the MuST-C corpus.

MuST-C is a multilingual speech translation corpus whose size and quality will facilitate the training of end-to-end systems for SLT from English into 14 languages (Arabic, Chinese, Czech, Dutch, French, German, Italian, Persian, Portuguese, Romanian, Russian, Spanish, Turkish and Vietnamese).
For each target language, MuST-C comprises several hundred hours of audio recordings from English TED Talks, which are automatically aligned at the sentence level with their manual transcriptions and translations.

### Supported Tasks and Leaderboards

- `machine-translation`: The dataset can be used to train a model for machine-translation.

## Dataset Structure

### Data Instances

Dataset example:

```
{
  "translation": {
    "en": "I'll tell you one quick story to illustrate what that's been like for me.", 
    "es": "Les diré una rápida historia para ilustrar lo que ha sido para mí."
  }
}
```

### Data Fields

The fields are:

- `translation`: an object containing two items, constructed as key-value pairs:
  - language code (key)
  - text (value)

abstract = {End-to-end spoken language translation (SLT) has recently gained popularity thanks to the advancement of sequence to sequence learning in its two parent tasks: automatic speech recognition (ASR) and machine translation (MT). However, research in the field has to confront with the scarcity of publicly available corpora to train data-hungry neural networks. Indeed, while traditional cascade solutions can build on sizable ASR and MT training data for a variety of languages, the available SLT corpora suitable for end-to-end training are few, typically small and of limited language coverage. We contribute to fill this gap by presenting MuST-C, a large and freely available Multilingual Speech Translation Corpus built from English TED Talks. Its unique features include: i) language coverage and diversity (from English into 14 languages from different families), ii) size (at least 237 hours of transcribed recordings per language, 430 on average), iii) variety of topics and speakers, and iv) data quality. Besides describing the corpus creation methodology and discussing the outcomes of empirical and manual quality evaluations, we present baseline results computed with strong systems on each language direction covered by MuST-C.}
