Claim 17:
18. A method within and by a computer hardware system including a hardware processor, comprising:
passively monitoring a time series of audio signals generated by a microphone of the computer hardware system for a cough event by a user;
filtering, by a cough detector within the hardware processor, portions of the audio signals that do not relate to the cough event to generate filtered audio signals;
generating, by a feature vector generator, a cough feature vector corresponding to the filtered audio signals, wherein each element of the cough feature vector corresponds to an audio signal feature extracted from the filtered audio signals; and
generating, by a regressor implemented by the hardware processor, a predicted lung function metric of the user based on the cough feature vector;
wherein the cough detector includes a cough segmenter configured to extract edges of a burst phase of the cough event and reject non-burst portions of the cough event, and the cough feature vector is generated only based upon the burst phase of the cough event.
