Claim 8:
9. A computing device for detecting a cough in an audio stream comprising:
one or more processors operable to perform operations, the operations comprising:
performing one or more pre-processing steps on the audio stream to generate an input audio sequence comprising a plurality of time-separated audio segments for a machine learning model;
generating an embedding for each of the segments of the input audio sequence using an audio feature set generated by a self-supervised triplet loss embedding model, the embedding model having been trained to learn the audio feature set in a self-supervised triplet loss manner from a plurality of speech audio clips from a speech dataset;
implementing a model performing cough detection inference on each generated embedding, wherein the model generates a probability that each of the segments of the input audio sequence includes a cough episode; and
generating cough metrics for each of the cough episodes detected in the input audio sequence.
