Dataset Card for TV3Parla

Dataset Summary

This corpus includes 240 hours of Catalan speech from broadcast material. The details of segmentation, data processing and also model training are explained in Külebi, Öktem; 2018. The content is owned by Corporació Catalana de Mitjans Audiovisuals, SA (CCMA); we processed their material and hereby making it available under their terms of use.

This project was supported by the Softcatalà Association.

Supported Tasks and Leaderboards

The dataset can be used for:

  • Language Modeling.
  • Automatic Speech Recognition (ASR) transcribes utterances into words.

Languages

The dataset is in Catalan (ca).

Data Fields

  • path (str): Path to the audio file.
  • 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].
  • text (str): Transcription of the audio file.

Data Splits

The dataset is split into "train" and "test".
