Abstract
Provided is a technique for accurately estimating a scene even when the number of input signals increases. A scene estimation method includes: when S is the number of scenes and M is the number of input acoustic signals, an acoustic signal encoding step of generating, by a scene estimation device, an integrated acoustic feature amount from an m-th input acoustic signal (m=1, . . . , M) and a position where the m-th input acoustic signal is acquired (hereinafter referred to as an m-th input acoustic signal acquisition position) (m=1, . . . , M); and a scene selection step of selecting, by the scene estimation device, a scene from which M input acoustic signals are acquired from among S scenes, using the integrated acoustic feature amount.
