## Dataset Description

This dataset contains noisy and enhanced speech samples with human-labeled mean opinion scores (MOS), which was constructed in the 2024 URGENT Speech Enhancement Challenge (https://urgent-challenge.github.io/urgent2024/), an official [NeurIPS 2024 Competition](https://neurips.cc/virtual/2024/competition/84788). The dataset is intended to facilitate research on speech quality assessment (SQA) and speech enhancement (SE) systems.

The dataset consists of the noisy and 22 enhanced versions of a subset (300 samples) of the [blind test dataset](https://huggingface.co/datasets/urgent-challenge/urgent2024_official) in the 2024 URGENT Speech Enhancement Challenge. In total, it 6900 speech samples with MOS labels (~13.8 hours).
> The MOS label for each speech sample were collected from 8 distinct human subjects through Amazon Mechanical Turk (MTurk) platform, following the P.808 recommendation. The raw ratings from each subject were averaged to obtain the final MOS score.
>
> Detailed information about the MOS collection process can be found in our [summary paper]() (to be released).

All speech samples in this dataset are in English, with a single microphone channel and sampling frequencies ranging from 8 kHz to 48 kHz.

## Example Usage

The dataset can be loaded using the [`datasets`](https://huggingface.co/docs/datasets/en/installation) library.

```python
from datasets import load_dataset

data = load_dataset("urgent-challenge/urgent2024_mos")

# Load a single sample
sample = data["test"][100]
print(sample)

# Iterate over all samples
# for idx, sample in enumerate(data["test"]):
#     print(sample)
```

This will generate the following output:

```json
{
  'id': 'P422-fileid_338',
  'audio': {'path': None, 'array': array([ 0.00027466, -0.00161743,  0.00033569, ...,  0.        , 0.        ,  0.        ]), 'sampling_rate': 16000},
  'sampling_rate': 16000,
  'mos': 2.5,
  'raw_ratings': [5, 4, 1, 2, 3, 1, 2, 2],
}
```

## Data fields

- `id`: Unique identifier for the sample.
- `audio`: Dictionary containing the audio data.
  - `path`: Path to the audio file (always `None` in this dataset).
  - `array`: Numpy array of the audio signal.
  - `sampling_rate`: Sampling rate of the audio signal in Hz.
- `sampling_rate`: Sampling rate of the audio signal in Hz.
- `mos`: Mean opinion score (MOS) for the audio sample, ranging from 1 (bad) to 5 (excellent).
- `raw_ratings`: List of raw ratings from human subjects, each ranging from 1 (bad) to 5 (excellent).

The `id` field follows the following unified format: "{participant_id}-{fileid}", where `participant_id` is the ID of the participant who generated the audio sample, and `fileid` is the ID of the audio file (shared among different participants).
