APNEA EPISODE DETERMINATION DEVICE AND APNEA EPISODE DETERMINATION METHOD
First Claim
1. An apnea episode determination device comprising:
- a processor; and
a memory which stores a plurality of instructions, which when executed by the processor, cause the processor to execute,detecting a breathing segment and a midway segment from a sound signal during sleep, the breathing segment being considered to include a breathing sound, the midway segment existing in between the breathing segments;
calculating an acoustic feature based on a background noise component and a signal component excluding the background noise component, which are included in the midway segment; and
determining that the midway segment is an apnea episode when the acoustic feature meets a preset condition.

14. An apnea episode determination method comprising:
-
detecting a breathing segment and a midway segment from a sound signal during sleep, the breathing segment being considered to include a breathing sound, the midway segment existing in between the breathing segments; calculating, by a computer processor, an acoustic feature based on a background noise component and a signal component excluding the background noise component, which are included in the midway segment; and determining that the midway segment is an apnea episode when the acoustic feature meets a preset condition.

15. A computer-readable storage medium storing an apnea episode determination program that causing a computer to execute a process comprising:
-
detecting a breathing segment and a midway segment from a sound signal during sleep, the breathing segment being considered to include a breathing sound, the midway segment existing in between the breathing segments; calculating an acoustic feature based on a background noise component and a signal component excluding the background noise component, which are included in the midway segment; and determining the midway segment as an apnea episode when the acoustic feature meets a preset condition.
