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. 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 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 library.
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:
{
'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],
}
