Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information processing apparatuses with voice operation capabilities face challenges in effectively implementing an auto-reset function due to ambient noise detection, leading to ineffective security measures.
Innovation Solution
Incorporating a voice input device and hardware processor that performs voice print authentication to identify users and adjust the auto-reset timing based on user identity, distinguishing between intended and unintended voice inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice operation is enabled to allow users to perform operations by uttering voice, then ease of operation is improved, but reliability deteriorates because ambient noise is detected as voice input causing false triggers
Solution Approach 1:
The system performs voice print authentication each time voice is input to verify the user identity, creating a feedback mechanism that distinguishes between authorized user voice and ambient noise. This authentication feedback loop ensures that only recognized user voices trigger operations, resolving the reliability issue while maintaining ease of operation.
Solution Approach 2:
Voice print authentication acts as an intermediary verification step between voice input detection and operation execution. This intermediary mechanism filters out ambient noise by authenticating the user identity before processing the voice command, thereby maintaining both ease of operation and reliability.
2Reliability
If auto-reset function is implemented to clear set values after predetermined time to enhance security, then security is improved, but ease of operation deteriorates because the function does not work effectively due to ambient noise detection
Solution Approach 1:
The auto-reset function incorporates voice print authentication feedback to determine whether to reset settings. When ambient noise is detected without valid user authentication, the system maintains security by not resetting, whereas genuine user voice input prevents unwanted resets. This feedback mechanism ensures the auto-reset function works effectively for security purposes.
Solution Approach 2:
Voice print authentication serves as an intermediary verification between ambient noise detection and auto-reset execution. This intermediary layer ensures that auto-reset only occurs when appropriate (when user intent is confirmed or time elapsed without authentication), preventing false triggers from ambient noise while maintaining security effectiveness.
3Reliability
If voice print authentication is performed each time voice is input to identify users, then reliability is improved by distinguishing authorized users, but device complexity increases
Solution Approach 1:
The voice input device serves multiple functions: it detects voice operations, performs voice print authentication, and triggers appropriate responses. By making the voice input device universal for both operation and authentication purposes, the system improves reliability without proportionally increasing device complexity, as the same hardware component handles multiple tasks.

AI summary
There is provided an information processing apparatus in which voice operation is enabled, the information processing apparatus including: a voice input device that accepts voice input for voice operation; and a hardware processor that: sets an inputted condition as a job; identifies a content of voice operation based on a voice inputted to the voice input device, and reflects the content of the voice operation in setting of the job; returns the job set by the hardware processor to an initial setting condition; identifies a user by performing voice print authentication; and changes a time until a setting condition of the job is returned to the initial setting condition by the hardware processor, between a case where a user who has uttered the voice inputted to the voice input device is changed in the voice print authentication and a case where the user is not changed.
