US Patent 11862141 Signal processing device and signal processing method

The present technology relates to a signal processing device, a signal processing method, and a program that allow for easier sound source separation. The signal processing device includes a sound source separation unit that recursively performs sound source separation on an input acoustic signal by using a predetermined sound source separation model learned in advance to separate a predetermined sound source from an acoustic signal for learning including the predetermined sound source. The present technology can be applied to a signal processing device.
