  • Publication number: 20250082297
    Abstract: A method for determining respiratory rate from an audio respiratory signal comprising capturing the audio respiratory signal generated by a subject using a microphone. The method also comprises segmenting the audio respiratory signal into a plurality of overlapping frames. For each frame of the plurality of overlapping frames, the method comprises extracting a signal envelope, computing an auto-correlation function, computing an FFT spectrum from the auto-correlation function and computing a respiratory rate of the subject using the FFT spectrum.
