INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND INFORMATION PROCESSING PROGRAM

In a conventional method of detecting a user position from footsteps of a user collected by microphones installed in a user's home, it is necessary to precisely align the microphones in advance to an extent of coordinates. This is inconvenient for both system and user. Provided is an information processing apparatus including an acquisition unit that acquires sound data recorded by a plurality of microphones installed in arbitrary places and relative positions, from the microphones, of footsteps included in the sound data, and a learning unit that generates a learning model by learning training data including the sound data as input and the relative positions as correct answers. As a result, precise positioning of the microphones in the user's home becomes unnecessary, and the user position can be detected in a more convenient manner for both the system and the user.
