The method includes acquiring a plurality of onset signals from the sound signal, wherein the onset signal has a predetermined time length; acquiring a plurality of spectrograms corresponding to each of the plurality of onset signals; determining whether each of the acquired plurality of spectrograms represents a cough using a cough determination model; and calculating a number of coughs included in the sound signal based on a time point of a cough signal. The cough signal is an onset signal corresponding to one spectrogram determined to represent the cough. When a time interval between a first time point of a first cough signal and a second time point of a second cough is within a reference time interval, the first cough signal and the second cough signal are regarded as one cough signal at the first time point.Type: ApplicationFiled: December 19, 2023Publication date: April 11, 2024Applicant: DAIN TECHNOLOGY, INC.Inventors: Jee Young SONG, Ji Young JUNG, Sang Youn KANG, Kyeong Yeon DOO, On Sub KIM, Ah Ra LEE
