# CORAA-v1.1

[CORAA-v1.1](https://github.com/nilc-nlp/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.

## Metadata

- file_path: the path to an audio file
- task: transcription (annotators revised original transcriptions); annotation (annotators classified the audio-transcription pair according to votes_for_* metrics); annotation_and_transcription (both tasks were performed)
- variety: European Portuguese (PT_PT) or Brazilian Portuguese (PT_BR)
- dataset: one of five datasets (ALIP, C-oral Brasil, NURC-RE, SP2010, TEDx Portuguese)
- accent: one of four accents (Minas Gerais, Recife, Sao Paulo cities, Sao Paulo capital) or the value "miscellaneous"
- speech_genre: Interviews, Dialogues, Monologues, Conversations, Interviews, Conference, Class Talks, Stage Talks or Reading
- speech_style: Spontaneous Speech or Prepared Speech or Read Speech
- up_votes: for annotation, the number of votes to valid the audio (most audios were revewed by one annotor, but some of the audios were analyzed by more than one).
- down_votes: for annotation, the number of votes do invalid the audio (always smaller than up_votes)
- votes_for_hesitation: for annotation, votes categorizing the audio as having the hesitation phenomenon
- votes_for_filled_pause: for annotation, votes categorizing the audio as having the filled pause phenomenon
- votes_for_noise_or_low_voice: for annotation, votes categorizing the audio as either having noise or low voice, without impairing the audio compression.
- votes_for_second_voice: for annotation, votes categorizing the audio as having a second voice, without impairing the audio compression
- votes_for_no_identified_problem: without impairing the audio as having no identified phenomenon (of the four described above)
- text: the transcription for the audio
