Claim 11:
12. A method of processing an acoustic heart signal, the method comprising:
capturing an acoustic heart signal from a patient;
processing the acoustic heart signal to provide an acoustic data sequence comprising a sequence of data elements representing the acoustic heart signal;
classifying the sequence of data elements using a neural network to provide a sequence of acoustic data category classifications and associated probabilities, each acoustic data category classification classifying one or more of the data elements into one of a plurality of acoustic heart data categories with an associated probability;
processing the sequence of acoustic data category classifications and associated probabilities using one or more sequence models, where each sequence model represents the likelihood of a sequence of heart sounds represented by the acoustic data category classifications and associated probabilities, wherein the processing identifies a most likely sequence of the heart sounds; and
outputting data identifying the most likely sequence of the heart sounds.
