Abstract
A method of generating a sympathetic back-channel signal is provided. The method includes receiving a voice signal from a user, determining whether predetermined timing is timing at which a back-channel signal is output in response to the input of the voice signal at the predetermined timing, storing the voice signal that has been input so far if the predetermined timing is the timing at which the back-channel signal is output as a result of the determination, determining back-channel signal information based on the stored voice signal, and outputting the determined back-channel signal information.
