Abstract
A speaker system includes a wearable speaker capable of outputting a first sound which is a voice of a communication partner of a talker and a second sound, a microphone, and a sound processing device which processes a sound output from the wearable speaker and a sound picked up by the microphone. The sound processing device generates a reference signal by synthesizing a first signal indicating the first sound and a second signal indicating the second sound, outputs the first signal and the second signal to the wearable speaker, obtains a sound pickup signal including the voice of the talker from the microphone, performs, on the sound pickup signal, a process of cancelling the sound component output from the wearable speaker by using the reference signal, and outputs the sound pickup signal on which the cancellation process has been performed.
