Sound source direction estimating apparatus, sound source direction estimating method, and sound source direction estimating program

摘要

The sound source direction estimating apparatus (100) divides a plurality of channels of acoustic signals (D1) acquired from a plurality of microphones into a plurality of frames in the time direction, thereby generating a plurality of frames of acoustic signals (D2). Unit (30), an input layer (50), a storage unit (80) for storing parameters (D3), a conversion network (60), and an output layer (70). The conversion network (60) 50) is performed based on the sound signal of the plurality of frames input to 50) and the parameter (D3) created based on the learning data, and the direction of the sound source (SS) is estimated. And a neural network (40) for outputting via (70).
