Abstract
A sound recognition apparatus can include a sound feature value calculating unit configured to calculate a sound feature value based on a sound signal, and a label converting unit configured to convert the sound feature value into a corresponding label with reference to label data in which sound feature values and labels indicating sound units are correlated. A sound identifying unit is configured to calculate a probability of each sound unit group sequence that a label sequence is segmented for each sound unit group with reference to segmentation data. The segmentated data indicates a probability that a sound unit sequence will be segmented into at least one sound unit group. The sound identity unit can also identify a sound event corresponding to the sound unit group sequence selected based on the calculated probability.
