Data processing with automatic switching back and forth from default voice commands to manual commands upon determination that subsequent input involves voice-input-prohibited information

An apparatus for executing a job including a plurality of processes comprising:

• a voice input unit configured to input voice in a voice input mode, the voice input mode being that, for causing the apparatus to execute a job, a specifying of a process included in the job and a specifying of a parameter relating to the specified process are performed by inputting of a voice;
• an operating unit configured to operate in an operating panel input mode, the operating panel input mode being that, for causing the apparatus to execute a job, a specifying of a process included in the job and a specifying of a parameter relating to the specified process are performed by inputting from an operating panel;
• a registering unit configured to register at least one of the plurality of processes as voice input-prohibited information;
• a determination unit configured to determine whether a process, which is specified by the voice input unit when the apparatus is in the voice input mode, corresponds to the voice input-prohibited information registered by the registering unit;
• a switching unit configured to, in a case where the determination unit determines that the specified process corresponds to the registered voice input-prohibited information, switch a mode from the voice input mode to the operating panel input mode in order to specify a parameter relating to the process, and automatically switch the mode from the operating panel input mode to the voice input mode in order to specify a next process after the parameter is specified by the operating unit;
• and
• a job execution unit configured to execute a job, in accordance with specifying of a plurality of processes and parameters relating to the processes by using the voice input unit and the operating unit.
