Project Coswara by Indian Institute of Science (IISc) Bangalore is an attempt to build a diagnostic tool for Covid-19 based on respiratory, cough and speech sounds. The project is in the data collection stage now. It requires the participants to provide a recording of breathing sounds, cough sounds, sustained phonation of vowel sounds and a counting exercise.

Each folder contains metadata and recordings corresponding to a person. The audio recordings are in wav format (44.1KHz).

Voice samples collected include breathing sounds (fast and slow), cough sounds (deep and shallow), phonation of sustained vowels (/a/ as in made, /i/,/o/), and counting numbers at slow and fast pace. Metadata information collected includes the participant's age, gender, location (country, state/ province), current health status (healthy/ exposed/ cured/ infected) and the presence of comorbidities (pre-existing medical conditions).

To download the data, you can merge the split tar files using the command below to obtain a single tar file and then untar it.

cat *.tar.gz.* > file_name.tar.gz

tar -xvzf file_name.tar.gz

Each folder also has a CSV file which contains metadata of each sample.
