Provided is a technique for providing feedback on the degree of utterance volume to an utterer. The utterance feedback device includes: an utterance volume evaluation unit that generates an evaluation value for a volume of an utterance voice (referred to as utterance volume evaluation value, hereinafter) from a first sound collection signal that is output by a first microphone installed near an utterer to collect an utterance voice, which is a voice of the utterer, and a second sound collection signal that is output by a second microphone installed at a position farther away from the utterer than the first microphone to collect the utterance voice; and a feedback sound signal generation unit that generates a signal for emitting, from a speaker, a feedback sound indicating the degree of the volume of the utterance voice to the utterer (hereinafter referred to as a feedback sound signal), from the first sound collection signal, by using a feedback gain corresponding to the utterance volume evaluation value.
