Dataset Summary
This is a streamable version of the Multilingual LibriSpeech (MLS) dataset. The data archives were restructured from the original ones from OpenSLR to make it easier to stream.
MLS dataset is a large multilingual corpus suitable for speech research. The dataset is derived from read audiobooks from LibriVox and consists of 8 languages - English, German, Dutch, Spanish, French, Italian, Portuguese, Polish.
Supported Tasks and Leaderboards
automatic-speech-recognition
,speaker-identification
: The dataset can be used to train a model for Automatic Speech Recognition (ASR). The model is presented with an audio file and asked to transcribe the audio file to written text. The most common evaluation metric is the word error rate (WER). The task has an active leaderboard which can be found at https://paperswithcode.com/dataset/multilingual-librispeech and ranks models based on their WER.

Dataset Structure
Data Instances
A typical data point comprises the path to the audio file, usually called file
and its transcription, called text
. Some additional information about the speaker and the passage which contains the transcription is provided.
{'file': '10900_6473_000030.flac',
'audio': {'path': '10900_6473_000030.flac',

'speaker_id': 10900,
'chapter_id': 6473,
'id': '10900_6473_000030'}
Data Fields
file: A filename .flac format.
audio: A dictionary containing the audio filename, the decoded audio array, and the sampling rate. Note that when accessing the audio column:
dataset[0]["audio"]
the audio file is automatically decoded and resampled todataset.features["audio"].sampling_rate
. Decoding and resampling of a large number of audio files might take a significant amount of time. Thus it is important to first query the sample index before the"audio"
column, i.e.dataset[0]["audio"]
should always be preferred overdataset["audio"][0]
.text: the transcription of the audio file.
id: unique id of the data sample.
speaker_id: unique id of the speaker. The same speaker id can be found for multiple data samples.
chapter_id: id of the audiobook chapter which includes the transcription.
