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 5):
The method of  claim 1 , wherein\n the section-by-section process is executed on each of N number of the section signals that are consecutively defined in a time domain to determine whether each of the N number of the section signals comprises a signal corresponding to a scream, a scream recognition process is performed, the scream recognition process comprising determining, when it is determined that a center frequency of a fundamental frequency band in which energy is concentrated among the N number of section signals has been increased and then decreased from past to present, whether a time duration during which the center frequency has been decreased is longer than a time duration during which the center frequency has been increased, and it is determined that a scream has occurred only when 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.
