Abstract:
A scream determination method for determining whether a window signal, selected by a window having a predetermined time length, among collected an audio signal includes a signal corresponding to the scream of a person, performs a process for each section, the process comprising the steps of: generating “FFT signals” and “S-FFT signals”; determining whether the number of points having a predetermined fifth reference value among the S-FFT signals satisfies a predetermined third condition; and determining whether energy patterns of predetermined specific frequency bands satisfy a predetermined fifth condition.

Claim (Index 6):
The method of  claim 5 , wherein\n the scream recognition process further comprises: before the determining whether the time duration during which the center frequency has been decreased is longer than the time duration during which the center frequency has been increased, determining whether there are M or more number of section signals including information on a scream of a person among the N number of section signals (where N>M); and when it is determined that there are the M or more section signals, determining among the N number of section signals whether there are P or more number of consecutive section signals on a time axis, information on a scream of a person being not included in each of the P or more number of consecutive section signals, wherein the determining whether the time duration during which the center frequency has been decreased is longer than the time duration during which the center frequency has been increased is executed only when it is determined that there are no P or more consecutive section signals on the time axis.
