Patent ID: 8655655

Claim:
A sound event detecting module of a sound event recognition system for detecting whether a sound event with the characteristic of repeating is generated, the module comprising: a sound end recognizing unit executed by the sound event recognition system for recognizing ends of sounds according to a sound signal to generate a plurality of sound sections and a plurality of sets of feature vectors of the sound sections correspondingly; a storage unit for storing at least M sets of feature vectors of the sets of feature vectors, wherein M is a positive integer; a similarity comparing unit executed by the sound event recognition system for comparing the at least M sets of feature vectors with each other, and generating a similarity score matrix correspondingly, wherein the similarity score matrix stores similarity scores of any two of the sound sections; and a correlation arbitrating unit executed by the sound event recognition system for converting the similarity score matrix into a correlation matrix that contains only values of 0 or 1, and for calculating the sum of each row of the correlation matrix to obtain the number of sound sections having high correlations to each other, wherein when the number is greater than a threshold value, it is indicated that the sound event with the characteristic of repeating is generated.
