Methods and apparatus for performing dynamic respiratory classification and tracking

A computer-readable storage medium having stored thereon, computer executable instructions that, if executed by a computer system cause the computer system to perform a method for performing acoustic dynamic classification of a breathing session, said method comprising:

• capturing breathing sounds of a subject using a microphone;
• processing said breathing sounds to generate an audio respiratory signal;
• recognizing a plurality of breath cycles and a plurality of breath phases within each of said plurality of breath cycles from said audio respiratory signal;
• detecting characteristics regarding said plurality of breath cycles and said plurality of breath phases;
• and
• extracting metrics concerning a breath pattern quality of said subject using said characteristics.

An apparatus for performing acoustic dynamic classification of a breathing session, said apparatus comprising:

• a microphone for capturing breathing sounds of a subject;
• a memory comprises an application for performing dynamic classification of a breathing session stored therein;
• and
• a processor coupled to said memory and said microphone, the processor being configured to operate in accordance with said application to:
• process said breathing sounds to generate an audio respiratory signal;
• recognize a plurality of breath cycles and a plurality of breath phases within each of said plurality of breath cycles from said audio respiratory signal;
• detect characteristics regarding said plurality of breath cycles and said plurality of breath phases;
• and
• extract metrics concerning a breath pattern quality of said subject using said characteristics.
