Voice Recognition for Power-Off Cancellation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of voice-operated home appliances, such as TVs and robot vacuum cleaners, face inconvenience when automatic power-off functions are triggered unexpectedly, requiring manual intervention to cancel or adjust settings, which can be inconvenient and disruptive.
Innovation Solution
An information processing device that allows voice operation without an activation word by presenting specific voice input options and performing voice recognition based on predetermined state transitions, enabling users to cancel or adjust settings through intuitive voice commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If automatic power off function is implemented, then energy saving is improved, but user convenience deteriorates when unintended power off occurs
Solution Approach 1:
The system performs preliminary action by notifying the user in advance before automatic power off occurs. A notification is displayed showing that automatic power off is scheduled, giving the user a chance to cancel it before execution. This resolves the contradiction by maintaining energy saving while preventing unintended power off through advance warning.
Solution Approach 2:
The system implements feedback by providing real-time information to the user about the automatic power off status. The notification displays whether automatic power off is active and when it will occur, allowing the user to make informed decisions. This feedback mechanism ensures energy saving while improving user convenience through transparency and control.
2Ease of operation
If voice operation without activation word is enabled, then ease of operation is improved, but voice recognition accuracy deteriorates
Solution Approach 1:
The system applies local quality by creating a localized voice recognition environment triggered by specific notifications. When the automatic power off notification is displayed, the system activates voice recognition specifically for that context. This localized approach maintains ease of operation while improving voice recognition accuracy by focusing on relevant commands in a specific context.
Solution Approach 2:
The system performs preliminary action by preparing the voice recognition system in advance when the automatic power off notification is displayed. The voice recognition function is activated and ready to receive commands before the user speaks, ensuring both ease of operation and high accuracy by being pre-configured for the specific task.
3Ease of operation
If voice recognition is always active, then ease of operation is improved, but energy consumption increases
Solution Approach 1:
The system implements periodic action by activating voice recognition only at specific intervals when the automatic power off notification is displayed, rather than keeping it continuously active. This periodic activation maintains ease of operation when needed while significantly reducing energy consumption during other periods.
Solution Approach 2:
The system applies self-service by automatically activating voice recognition only when the automatic power off notification is displayed, without requiring continuous monitoring or user initiation. The system serves itself by intelligently determining when voice recognition is needed, balancing ease of operation with energy efficiency.

AI summary
An information processing device presents first information indicating that voice input for the voice operation is possible and second information representing a domain of utterance in which voice operation is possible in response to an occurrence of a predetermined state transition, and performs voice recognition for voice input by a user.
