US Patent 11289081 Refrigerator

In a refrigerator, when a door switch detects opening of a door of the refrigerator, a voice recognition control unit determines whether voice data acquired by a voice acquisition unit satisfies a predetermined voice recognition start condition. In a case where the voice recognition start condition is satisfied, the recognition control unit controls the voice recognition unit to perform voice recognition. However, in a case where the voice recognition start condition is not satisfied, the recognition control unit controls the voice recognition unit not to perform voice recognition.
