A method for stratifying severity of asthma of a patient initially comprises receiving acoustic data corresponding to sounds of the patient from an acoustic sensor and identifying, by a processor, at least one cough sound in the acoustic data. With or without the patient being present, the method further involves determining, by operation of the processor, one or more overall cough sound feature values of the at least one cough sound for each of one or more characteristic features. The overall cough sound feature values are then applied to a classifier that is implemented by the processor and which has been pre-trained with a training set of characteristic feature values from a population of asthmatic and non-asthmatic subjects. The method then involves monitoring an output from the pre-trained classifier to deem the patient cough sound as indicating one of a number of degrees of severity of asthma.
