A method for stratifying asthma severity in a patient includes first receiving acoustic data corresponding to sounds of the patient from an acoustic sensor; and identifying, by a processor, at least one coughing sound in the acoustic data. step. Whether or not a patient is present, the method determines, by operation of the processor, one or more overall cough sound features of at least one cough sound for each of the one or more characteristic features. with more steps. The synthetic cough sound features are then applied to a classifier implemented by a processor and pretrained with a training set of unique features from a population of asthmatic and non-asthmatic subjects. The method then involves monitoring the output from a pretrained classifier to interpret the patient's cough sounds as indicative of one of several degrees of asthma severity. |
