The purpose of the present invention is to achieve a device and a method that make it possible to perform voice recognition based on clear user utterance by removing an external apparatus output sound from a voice inputted through a voice input unit. A user utterance voice extraction unit extracts a user utterance voice from a microphone input sound. The user utterance voice extraction unit analyzes a sound source direction of the input sound, determines whether or not the input sound includes an external apparatus output sound on the basis of a sound source direction of the external apparatus output sound recorded in a database, removes, when determining that the external apparatus output sound is included, from the input sound a sound signal corresponding to a feature amount, such as frequency characteristics, of the external apparatus output sound recorded in the database, and extracts the user utterance voice from which the external apparatus output sound has been removed.
