## Dataset Description
YODAS-Granary is a curated subset of the larger [`nvidia/Granary`](https://huggingface.co/datasets/nvidia/Granary) dataset, focusing on high-quality pseudo-labeled speech data for Automatic Speech Recognition (ASR) and Automatic Speech Translation (AST) across 23 European languages.

### Overview
<table style="width:100%; table-layout:auto;">
  <tr>
    <td style="vertical-align:middle; text-align:center;">
      <img src="./scheme.png" style="max-width:100%;">

    <td style="vertical-align:middle; padding-left:20px;">
      <p>
        Derived from the <a href=https://huggingface.co/datasets/espnet/yodas2) target="_blank"><code>espnet/yodas2</code></a> corpus, YODAS-Granary provides high-quality pseudo-labeled speech data, focusing on two core tasks:
      </p>
      <ul>
        <li><strong>Automatic Speech Recognition (ASR)</strong>: covers 23 European languages, with pseudo-labeled transcriptions generated using the <a href="https://huggingface.co/Systran/faster-whisper-large-v3" target="_blank"><code>Systran/faster-whisper-large-v3</code></a> model, post-processed to restore punctuation and capitalization using <a href="https://huggingface.co/Qwen/Qwen2.5-7B-Instruct" target="_blank"><code>Qwen/Qwen2.5-7B-Instruct</code></a>, and filtered for quality.</li>
        <li><strong>Automatic Speech Translation (AST)</strong>: covers 22 non-English languages and consists of high-quality translations into English, generated from <code>ASR</code> subset using the <a href="https://huggingface.co/utter-project/EuroLLM-9B-Instruct" target="_blank"><code>utter-project/EuroLLM-9B-Instruct</code></a> model and filtered for quality.</li>
      </ul>

### Data Distribution
The following chart illustrates the distribution of data in the YODAS-Granary dataset across 23 European languages, measured in number of words (left) and total hours of audio (right), for both ASR and AST tasks.

<p align="center">
  <img src="./chart.png" width="100%"/><br>
  <em>πŸ” AST data is always a filtered subset of ASR, which is why AST bars are never taller than their ASR counterparts.<br>πŸ—£οΈ The English subset contains ASR data only.</em>
</p>

The table below summarizes the storage footprint and sample counts per language in the YODAS-Granary dataset, broken down into corresponding [splits](#data-splits):
- `ast` β€” the size and number of translated samples (X β†’ English),
- `asr_only` β€” samples that exist only in the ASR subset and have no corresponding translation,

and combined size and number of all samples per language (`total`).

## How to use
### Standard Loading
You can load the dataset using the `datasets` library from Hugging Face:

```python
from datasets import load_dataset
```

**πŸ”Ή Load the entire dataset:**
```python
ds = load_dataset("espnet/yodas-granary")
```

**πŸ”Ή Load a single language (e.g., Italian):**
```python
ds = load_dataset("espnet/yodas-granary", "Italian")
```

### Streaming
Some language subsets are quite large and may not fit comfortably in memory. For efficient access and analysis without downloading the entire dataset, we recommend using streaming mode:

``` python
ds = load_dataset("espnet/yodas-granary", "English", streaming=True)
```

## Dataset Structure
### Data Instance
Each utterance in the dataset includes the following fields: `utt_id`, `audio`, `duration`, `lang`, `task`, `text`, `translation_en` (`null` in `asr_only`), `original_audio_id`, and `original_audio_offset`.

**Typical entry** 

from `data/de101/translation/00000000.parquet`

```python
{
  "utt_id": "de101_00000000_Z0_gcPJVTqg_1004_62_1_74",
  "audio": {
    'path': 'de101_00000000_Z0_gcPJVTqg_1004_62_1_74.wav', 
    'bytes': ... 
  }
  "duration": 1.74,
  "lang": "<de>",
  "task": "<ast>",
  "text": "Ich muss mir das Zeug mal aus der NΓ€he ansehen.",
  "translation_en": "I have to take a closer look at this stuff.",
  "original_audio_id": "Z0_gcPJVTqg",
  "original_audio_offset": 1004.62
}
```

### Data Fields

| **Field** | **Type** | **Description** |
|---|---|---|
| `utt_idΒΉ` | `string` | Unique identifier of the utterance, referencing the original segment. |
| `audio` | `Audio (16 kHz)` | Audio data of the utterance, stored as PCM waveform. |
| `duration` | `float64` | Duration of the utterance in seconds. |
| `lang` | `string` | Language of the utterance, in ISO 639-1 code (e.g., `<de>` for German). |
| `task` | `string` | Task type: either `<asr>` for transcription or `<ast>` for translation to English. |
| `text` | `string` | Transcription of the utterance in its original language. |
| `translation_en` | `string` | English translation of the utterance. `null` if split is `asr_only`. |
| `original_audio_id` | `string` | ID of the original audio file. This value corresponds to the `audio_id` field from the [`espnet/yodas2`](https://huggingface.co/datasets/espnet/yodas2) dataset. |
| `original_audio_offset` | `float64` | Start time (in seconds) of the utterance within the original audio file. |

ΒΉ - `utt_id` is encoded as `<subset>_<shard>_<wav_id>_<start_time_s>_<start_time_decimals>_<duration_s>_<duration_decimals>`, where `subset`, `shardΒ²`, and `wav_id` match the utterance's location in the original [`espnet/yodas2`](https://huggingface.co/datasets/espnet/yodas2) archive.

Β² - `shard` indices reflect those in [`espnet/yodas2`](https://huggingface.co/datasets/espnet/yodas2), but some shards are missing due to filtering during data processing. In particular, `bg000` is missing shard `00000011`, `en000` is missing shard `00000308`, `en003` is missing shard `00000221`, `en118` is missing shard `00000240`. 

### Data Splits
The dataset is organized into language-specific subsets, each containing one or two splits, depending on the language:

- **For non-English languages:**
  - `<ast>` – samples with **both high-quality transcriptions and translations** into English.
  - `<asr_only>` – samples that passed transcription quality checks but do not include translations.
- **For `English`**:
  - `<asr_only>` split is available only, since English-to-English translation is not applicable.
