Nos_TranscriSpeech-GL: Galician ASR corpus


Manually transcribed and speech-to-text aligned Galician ASR corpus containing 53 hours of multi-domain speech.

The corpus is divided into four subcorpora according to the type of audio: conferences, debates, speeches, and interviews.

The file naming scheme of both the audio and the transcription files consists of an ID indicating the speaker, followed, if necessary, by a number indicating successive audios by the same speaker. Parts of the same audio are marked by a number separated by an underscore from the speaker ID (e.g., Alberti1_1.wav).

The audio files are released in 44.1 kHz 16-bit WAV format and the transcriptions are available in .stm and .trf. Moreover, the corpus is accompanied by the corresponding speaker metadata and the guide detailing the conventions used for the manual transcription.
