### CORAA V1 - Dataset 

CORAA is a publicly available dataset for Automatic Speech Recognition (ASR) in the Brazilian Portuguese language containing 290.77 hours of audios and their respective transcriptions (400k+ segmented audios). The dataset is composed of audios of 5 original projects:

* ALIP (Gonçalves, 2019)
* C-ORAL Brazil (Raso and Mello, 2012)
* NURC-Recife (Oliviera Jr., 2016)
* SP-2010 (Mendes and Oushiro, 2012)
* TEDx talks (talks in Portuguese)
The audios were either validated by annotators or transcripted for the first time aiming at the ASR task.
