Abstract
Provided is a signal processing device that includes a voice detection unit that, based on a mixed audio signal containing a sound of a target sound source and a sound of a non-target sound source different from the target sound source, detects a time segment of the sound of the target sound source from the mixed audio signal; and a voice determination unit that, based on label information indicating the time segment of the sound of the target sound source in an audio signal of the target sound source and a detection result for the time segment of the sound of the target sound source, performs determination processing for determining whether the sound of the target sound source in the mixed audio signal is easy to hear.
