| Abstract(in English) | Recently, as crimes have become more diverse and increasingly sophisticated, our awareness of security systems has increased. The most typical kind of security system is a security camera, but there are various issues in that there are situations in which they cannot be used, such as from consideration of privacy or in darkness. For that reason, security systems that utilize sound information have been proposed. This report relates to scream identification and scream detection systems that focuses on screams within various sounds, and proposes techniques increasing its noise robustness. More specifically, we use spectral entropy, which expresses the difference in frequency distribution between a scream and noise, as a feature, and also construct a scream Gaussian mixture model (GMM) from screams with superimposed noise. In scream identification and scream detection experiments under noisy environments, the proposed method could be improved the equal error rate under all noisy environment, in comparison with the conventional method. |
