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 1):
A method for operating a scream detection system comprising a terminal, a server, and a third terminal, the method comprising:\n determining, at the terminal, whether or not a scream has occurred using an audio signal collected through a microphone of the terminal; transmitting, at the terminal, information regarding the scream to the server if the terminal determined that a scream has occurred; and transmitting, at the server, a fact that a scream has occurred to the third terminal; wherein, the terminal is a scream determination device including a processing unit configured to determine whether a window signal selected by a window having a predetermined time length among a collected audio signal includes a signal corresponding to a human scream, and the processing unit is configured to perform a section-by-section process comprising: {circle around (1)} performing a Fourier transform on a section signal defined in the window signal to generate a FFT signal, which is a frequency domain signal obtained by the Fourier transform; {circle around (2)} smoothing a shape of the FFT signal to generate a S-FFT signal which is a frequency domain signal obtained by the smoothing, and determining whether a number of points of the S-FFT signal which has a predetermined fifth reference value satisfies a predetermined third condition; and {circle around (3)} determining whether an energy pattern of predetermined specific frequency bands of the S-FFT signal satisfies a predetermined fifth condition, wherein the determining of whether the fifth condition is satisfied is performed only when the third condition is satisfied, and only if the fifth condition is satisfied, it is determined that the section signal includes a signal corresponding to a scream, and if not, it is determined that the section signal does not include a signal corresponding to a scream.
