PROBLEM TO BE SOLVED: To provide a sound recognition device, a sound recognition method, and a sound recognition program which can recognize a variety of general sounds.SOLUTION: A sound feature quantity calculation part calculates a sound feature quantity on the basis of a sound signal, and a label conversion part converts it into a label corresponding to the sound feature quantity with reference to label data showing correlation between the sound feature quality and a label showing a sound unit to be a sound constituent unit. A sound identification part calculates probability every sound unit group system where a label system formed by the label is divided every sound unit group with reference to division data showing probability by which to divided at least one sound unit into at least one sound unit group, selects a sound unit group system whose calculated probability is the highest, and identifies a sound event corresponding to the selected sound unit group system with reference to sound event data showing the sound unit group system every sound event. |
