Dataset Card for festcat_trimmed_denoised
This is a post-processed version of the Catalan Festcat speech dataset. The data can be found here.
Dataset Details
Dataset Description
We processed the data of the Catalan Festcat with the following recipe:
- Trimming: Long silences from the start and the end of clips have been removed.
- py-webrtcvad -> Python interface to the Voice Activity Detector (VAD) developed by Google for the WebRTC.
- Resampling: From 48000 Hz to 22050 Hz, which is the most common sampling rate for training TTS models
- Resampler from CoquiTTS framework
- De-noising: Although base quality of the audios is high, we could remove some background noise and small artifcats thanks to the CleanUNet denoiser developed by NVIDIA.
We kept the same number of wave files, also the original anonymized file names and transcriptions.

Uses
The purpose of this dataset is mainly for training text-to-speech and automatic speech recognition models in Catalan.
Dataset Structure
The dataset consists of a single split, providing audios and transcriptions:
DatasetDict({
train: Dataset({
features: ['audio', 'transcription'],
num_rows: 4240
})
})
Each data point is structured as:
>> data['train'][0]['audio']
{'path': 'caf_09901_01619988267.wav',
'array': array([-3.05175781e-05, -3.05175781e-05, -3.05175781e-05, ..., -6.10351562e-05, -6.10351562e-05, -6.10351562e-05])
'sampling_rate': 22050}
>> data['train'][0]['transcription']
"L'òpera de Sydney es troba a l'entrada de la badia"
Dataset Splits
audio (dict): A dictionary containing the path to the downloaded audio file, 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 to dataset.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 over dataset["audio"][0].
- path (str): The path to the audio file.
- array (array): Decoded audio array.
- sampling_rate (int): Audio sampling rate.
transcription (str): The sentence the user was prompted to speak.
