An information processing device includes an input unit, an extracting unit, an output unit, and a specifying unit. The input unit receives a voice operation. The extracting unit extracts a processing detail corresponding to the voice operation received by the input unit. When the processing detail corresponding to the voice operation received by the input unit cannot be specified, the output unit outputs response information for the user to make a selection of at least one processing detail from a plurality of processing details extracted by the extracting unit. The specifying unit specifies the processing detail selected from among the plurality of processing details contained in the response information as the processing detail corresponding to the voice operation received by the input unit.
