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.

Information processing device and method for outputting a target sound signal from a mixed sound signal

A speech separation device () of a speech separation system includes a feature amount extraction unit () configured to extract time-series data of a speech feature amount of mixed speech, a block division unit () configured to divide the time-series data of the speech feature amount into blocks having a certain time width, a speech separation neural network () configured to create time-series data of a mask of each of a plurality of speakers from the time-series data of the speech feature amount divided into blocks, and a speech restoration unit () configured to restore the speech data of each of the plurality of speakers from the time-series data of the mask and the time-series data of the speech feature amount of the mixed speech.
