Nos_ParlaSpeech-GL: Galician ASR corpus

This corpus is publicly accessible upon accepting T&Cs and requesting access.

Nos_ParlaSpeech-GL is an ASR corpus of more than 1,600 hours of automatically aligned speech and text, created from audio and official transcripts of Galician parliamentary sessions celebrated between 2015 and 2022. The content belongs to the Galician Parliament and the data is released according to their terms of use.

The corpus is split into two subcorpora, "clean" and "other". The segments included in the "clean" subcorpus were filtered according to several alignment quality criteria, whereas the "other" subcorpus comprises the segments that were discarded in the filtering process. The details of both subcorpora can be found in the table below:

Moreover, each speech segment is tagged with the ID of its corresponding speaker. Metadata of the different speakers, compiled within the ParlaMint-GL project, can be accessed here.

The file naming scheme of the audio files consists of an ID comprising: a four-letter code in capitals denoting the source of the data (Minutes of the Galician Parliament), followed by a 3-digit number identifying the session number and an 8-digit date number in the DDMMYYYY format, all separated by underscores (e. g., DSPG_095_27012015.wav).

For the transcription files, this ID is preceded, separated by an underscore, by the word indicating the subcorpus to which the file belongs to: "clean" or "other" (e. g., clean_DSPG_095_27012015.stm, other_DSPG_095_27012015.stm).

The corpus is available in STM and JSON formats, and the audio files are released in 16 kHz 16-bit WAV format.

Hugging Face version

The corpus is also available in Hugging Face.

We are not responsible for any inconsistencies in speaker identification that stem from misidentification in the original transcripts.
