Abstract :
A system which detects hazardous sounds and situations in daily life was proposed. Feature vectors were consisted of spectral flux and 12 MFCCs which were extracted from a recorded daily sound. Clustering of daily sound (non-hazardous sound) by the complete link method was discussed. Probability model of the daily sound was created, and ten simulated hazardous sounds were examined with the probability model. Feasibility of detecting hazardous sound by the probability model was confirmed.
