1. A method for determining when a person is snoring, the method comprising:
- determining a candidate snore event, which comprises;
detecting the occurrence of a person'"'"'s breath using a sensor; and
detecting the occurrence of a sound event by measuring sound energy using a microphone, wherein the occurrence of the sound event is detected when a peak sound energy occurrence ratio is greater than a threshold ratio, the peak sound energy occurrence ratio being the temporal location of the peak sound energy expressed as a fraction relative to the total duration of the sampled sound energy; and
confirming that the candidate snore event is not an isolated snore event by determining that breaths immediately preceding and following the candidate snore event include other candidate snore events.

Abstract
The invention provides a method for determining when a person is snoring by determining a candidate snore event by detecting the occurrence of a person'"'"'s breath, and detecting the occurrence of a sound event. The method further includes confirming that the candidate snore event is not an isolated snore event by determining that breaths immediately preceding and following the candidate snore event include other candidate snore events.

16. A system for determining a snore event comprising:
-
a processor; and a computer readable memory operatively coupled to the processor and configured with instructions for causing the processor to perform a method for determining when a person is snoring, the method comprising; determining a candidate snore event, which comprises; detecting the occurrence of a person'"'"'s breath using a sensor; and detecting the occurrence of a sound event by measuring sound energy using a microphone, wherein the occurrence of the sound event is detected when a peak sound energy occurrence ratio is greater than a threshold ratio, the peak sound energy occurrence ratio being the temporal location of the peak sound energy expressed as a fraction relative to the total duration of the sampled sound energy; and confirming that the candidate snore event is not an isolated snore event by determining that breaths immediately preceding and following the candidate snore event include other candidate snore events.

19. A method for determining a snore event, comprising:
-
detecting, using a sensor, the occurrence of a person'"'"'s breath when the person'"'"'s breath has a volume that is less than a breath threshold; detecting, using a microphone, the occurrence of a sound event from sound energy sampled near a person'"'"'s mouth or nose when; the sampled sound energy is greater than a sound event threshold and lasts longer than a sound event period; and a peak sound energy occurrence ratio is greater than a threshold ratio, the peak sound energy occurrence ratio being the temporal location of the peak sound energy expressed as a fraction relative to the total duration of the sampled sound energy; and determining that the detected sound event is a candidate snore event when; a pitch of the sampled sound energy of the sound event is greater than a minimum sound energy pitch and less than a maximum sound energy pitch; and a fraction of the sampled sound energy that occurs during inspiration is greater than an inspiration threshold. - View Dependent Claims (20, 21, 22, 23, 24, 25)
