Dataset Summary
CML-TTS is a recursive acronym for CML-Multi-Lingual-TTS, a Text-to-Speech (TTS) dataset developed at the Center of Excellence in Artificial Intelligence (CEIA) of the Federal University of Goias (UFG). CML-TTS is a dataset comprising audiobooks sourced from the public domain books of Project Gutenberg, read by volunteers from the LibriVox project. The dataset includes recordings in Dutch, German, French, Italian, Polish, Portuguese, and Spanish, all at a sampling rate of 24kHz.
The data archives were restructured from the original ones from OpenSLR to make it easier to stream.
Supported Tasks
text-to-speech
,text-to-audio
: The dataset can also be used to train a model for Text-To-Speech (TTS).
Languages
The dataset includes recordings in Dutch, German, French, Italian, Polish, Portuguese, and Spanish, all at a sampling rate of 24kHz.
How to use
The datasets
library allows you to load and pre-process your dataset in pure Python, at scale. The dataset can be downloaded and prepared in one call to your local drive by using the load_dataset
function.
For example, to download the German config, simply specify the corresponding language config name (i.e., "german" for German):
from datasets import load_dataset
mls = load_dataset("ylacombe/cml-tts", "german", split="train")
Using the datasets library, you can also stream the dataset on-the-fly by adding a streaming=True
argument to the load_dataset
function call. Loading a dataset in streaming mode loads individual samples of the dataset at a time, rather than downloading the entire dataset to disk.
from datasets import load_dataset
mls = load_dataset("ylacombe/cml-tts", "german", split="train", streaming=True)
print(next(iter(mls)))
Bonus
You can create a PyTorch dataloader directly with your own datasets (local/streamed).
Local:
from datasets import load_dataset
from torch.utils.data.sampler import BatchSampler, RandomSampler
mls = load_dataset("ylacombe/cml-tts", "german", split="train")
batch_sampler = BatchSampler(RandomSampler(mls), batch_size=32, drop_last=False)
dataloader = DataLoader(mls, batch_sampler=batch_sampler)
Streaming:
from datasets import load_dataset
from torch.utils.data import DataLoader
mls = load_dataset("ylacombe/cml-tts", "german", split="train", streaming=True)
dataloader = DataLoader(mls, batch_size=32)

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.
{'audio': {'path': '6892_8912_000729.wav', 'array': array([-1.52587891e-...7344e-05]), 'sampling_rate': 24000}, 'wav_filesize': 601964, 'text': 'Proszę pana, tu pano... zdziwiony', 'transcript_wav2vec': 'proszę pana tu panow... zdziwiony', 'levenshtein': 0.96045197740113, 'duration': 13.648979591836737, 'num_words': 29, 'speaker_id': 6892}
Data Fields
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.
speaker_id: unique id of the speaker. The same speaker id can be found for multiple data samples.
transcript_wav2vec: the transcription of the audio file using the wav2vec model. Has been used to curate the dataset.
wav_filesize: The size of the audio waveform file. Has been used to curate the dataset.
levenshtein: The Levenshtein distance between the wav2vec transcription and the original transcription. Has been used to curate the dataset.
duration: The duration of the audio in seconds.
num_words: The number of words of the transcription.
