FLEURS-HS VITS

An extension of the FLEURS dataset for synthetic speech detection using text-to-speech, featured in the paper Synthetic speech detection with Wav2Vec 2.0 in various language settings.

This dataset is 1 of 3 used in the paper, the others being:

• FLEURS-HS
  • the default train, dev and test sets
  • separated due to different licensing
• ARCTIC-HS
  • extension of the CMU_ARCTIC and L2-ARCTIC sets in a similar manner

Dataset Details

Dataset Description

The dataset features 8 languages originally seen in FLEURS:

• German
• English
• Spanish
• French
• Italian
• Dutch
• Polish
• Swedish

The synthetic samples are generated using:

• Google Cloud Text-To-Speech
• Azure Text-To-Speech
• Amazon Polly

Only the test VITS samples are provided. For every VITS voice, which is in practice specific model weights, one sample per transcript is provided.

• Curated by: KONTXT by RealNetworks
• Funded by: RealNetworks
• Language(s) (NLP): English, German, Spanish, French, Italian, Dutch, Polish, Swedish
• License: Apache 2.0 for the code, CC BY 4.0 for the dataset (but various licenses depending on the source for VITS samples)

Dataset Sources

The original FLEURS dataset was downloaded from HuggingFace.

• FLEURS Repository: HuggingFace

• FLEURS Paper: arXiv

• Paper: Synthetic speech detection with Wav2Vec 2.0 in various language settings

Uses

This dataset is best used as a difficult test set. Each sample contains an Audio feature, and a label, which is always synthetic; this dataset does not include any human samples.

Direct Use

The following snippet of code demonstrates loading the training split for English:

from datasets import load_dataset

fleurs_hs = load_dataset(
    "realnetworks-kontxt/fleurs-hs-vits",
    "en_us",
    split="test",
    trust_remote_code=True,
)

To load a different language, change en_us into one of the following:

• de_de for German
• es_419 for Spanish
• fr_fr for French
• it_it for Italian
• nl_nl for Dutch
• pl_pl for Polish
• sv_se for Swedish

This dataset only has a test split.

The trust_remote_code=True parameter is necessary because this dataset uses a custom loader. To check out which code is being ran, check out the loading script.

Dataset Structure

The dataset data is contained in the data directory.

There exists 1 directory per language.

Within that directory, there is a directory named splits; it contains 1 file per split:

• test.tar.gz

That .tar.gz file contains 1 or more directories, named after the VITS model being used: ex. thorsten-vits

Each of these directories contain .wav files. Each .wav file is named after the ID of its transcript. Keep in mind that these directories can't be merged as they share their file names. An identical file name implies a speaker-voice pair, ex. human/123.wav and thorsten-vits/123.wav.

Finally, back to the language directory, it contains 3 metadata files, which are not used in the loaded dataset, but might be useful to researchers:

• recording-metadata.csv
  • contains the transcript ID, file name, split and gender of the original FLEURS samples
• recording-transcripts.csv
  • contains the transcrpits of the original FLEURS samples
• voice-metadata.csv
  • contains the groupation of TTS' used alongside the splits they were used for

Sample

A sample contains contains an Audio feature audio, and a string label.

{
  'audio': {
    'path': 'ljspeech-vits/1660.wav',
    'array': array([0.00119019, 0.00109863, 0.00106812, ..., 0., 0., 0.]),
    'sampling_rate': 16000
  },
  'label': 'synthetic'
}
