INFORMATION PROCESSING DEVICE, AND OUTPUT METHOD

An information processing device includes an acquisition unit that acquires sound source position information and so forth, a sound feature value extraction unit that extracts a plurality of sound feature values based on the mixed sound signal, an emphasis unit that emphasizes a sound feature value in a target sound direction based on the sound source position information, an estimation unit that estimates the target sound direction based on the sound source position information and so forth, a mask feature value extraction unit that extracts a mask feature value based on the estimated target sound direction and so forth, a generation unit that generates a target sound direction emphasis sound signal and generates a target sound direction masking sound signal, and a target sound signal output unit that outputs a target sound signal by using the target sound direction emphasis sound signal and so forth.
