A guiding device comprising: a receiving section configured to receive a voice; and an output control section configured to, when information is identified as a result of recognition of the voice, perform control so as to output a guidance related to a volume at which to input voice in a mode corresponding to a recognition ranking of the information, further comprising a state changing section configured to change to a voice recognition state allowing input of a predetermined command by voice when the information is identified as a result of recognition of the voice received in a normal state not allowing input of the command by voice, the recognition ranking of the information is a first place, and an SNR value is larger than a predetermined value; wherein the state changing section is configured to change to the voice recognition state allowing input of a predetermined command by voice and the output control section performs control so as to output the guidance once in the voice recognition state when: the information is identified as a result of recognition of the voice received in the normal state, the recognition ranking of the information is a first place, and an SNR value is less than or equal to a predetermined value; and wherein the output control section performs control so as to output the guidance while remaining in the normal state when the information is identified as a result of recognition of the voice received in the normal state, the information is a recognition result but the recognition ranking of the information is other than the first place, and an SNR value is less than or equal to a predetermined value. a receiving section configured to receive a voice; and an output control section configured to, when information is identified as a result of recognition of the voice, perform control so as to output a guidance related to a volume at which to input voice in a mode corresponding to a recognition ranking of the information, further comprising a state changing section configured to change to a voice recognition state allowing input of a predetermined command by voice when the information is identified as a result of recognition of the voice received in a normal state not allowing input of the command by voice, the recognition ranking of the information is a first place, and an SNR value is larger than a predetermined value; wherein the state changing section is configured to change to the voice recognition state allowing input of a predetermined command by voice and the output control section performs control so as to output the guidance once in the voice recognition state when: the information is identified as a result of recognition of the voice received in the normal state, the recognition ranking of the information is a first place, and an SNR value is less than or equal to a predetermined value; and wherein the output control section performs control so as to output the guidance while remaining in the normal state when the information is identified as a result of recognition of the voice received in the normal state, the information is a recognition result but the recognition ranking of the information is other than the first place, and an SNR value is less than or equal to a predetermined value. <EOS>
