  • Patent number: 11073900
    Abstract: A device for monitoring respiration by a user determines whether sound represented by audio data corresponds to an exhalation. For example, the device receives audio data representing sound, determines a frequency spectrum for the audio data (e.g., amplitude distributions of one or more frequencies, etc.), and identifies various frequency bands of interest. Here, the device identifies a first frequency band corresponding to respiration, a second frequency band corresponding to noise, and a third frequency band corresponding to voice harmonics. The device applies a gain to the first frequency band to create an amplified first frequency band, filters or nulls the second frequency band, and inverts the third frequency band to create an inverted third frequency band. The device determines the frequency spectrum corresponds to an exhalation based on a slope value over the amplitude distributions of the amplified first frequency band and the inverted third frequency band.
