Ann: Results from Data Confirmation Study, page-269

Please correct me if I read the announcement wrong, we tested 1300 new independently supplied cough sounds. My question is, it took us months to collect coughs in the Sates and India in the right conditions. Who had 1300 cough sound ready for us to test on a short notice, and on which phones was these recordings made, how far was the coughs made from the phone, what about the back ground noise, or did they retest our previos recorded cough sounds, serious question guys
