Voice Command Risk Assessment for False Operation Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional speech recognition devices face issues with false operations and privacy leaks due to the lack of effective mechanisms to differentiate between intended and unintended user utterances, leading to erroneous processes and potential data breaches.
Innovation Solution
An information processing device and system that includes a limited utterance determination unit, a risk determination unit, and a process execution unit to assess the risk of user utterances and prompt users to make pre-registered limited utterances, thereby reducing false operations and privacy leaks by providing guidance and controlling process execution based on risk levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a startup word configuration is used to prevent false operations, then reliability is improved, but ease of operation deteriorates due to the need to utter the startup word each time
Solution Approach 1:
The system performs preliminary analysis of the utterance content to determine risk level before executing the command. By pre-evaluating whether an utterance contains private information or poses a risk of false operation, the system can prevent erroneous execution without requiring a startup word for every command, thus improving convenience while maintaining reliability.
2Reliability
If sequential setting of publication condition for each privacy information is implemented, then reliability is improved, but device complexity increases due to heavy user burden
Solution Approach 1:
The system automatically determines whether an utterance contains private information by analyzing the content itself, without requiring users to pre-configure publication conditions for each type of information. The risk determination unit self-evaluates the utterance to identify private information such as names, addresses, and contact details, thereby preventing privacy leakage without imposing complex setting burdens on users.
3Reliability
If risk determination and guidance output are implemented for non-low-risk processes, then reliability is improved, but productivity decreases due to additional processing steps
Solution Approach 1:
The system applies different processing levels to different types of utterances based on their risk characteristics. For low-risk utterances, the system executes commands directly without additional guidance, maintaining high response speed. For high-risk utterances containing private information or potential false operations, the system performs risk determination and outputs guidance before execution, ensuring accuracy. This localized quality approach optimizes both reliability and productivity.

AI summary
Provided is a limited utterance determination unit that determines whether or not a user utterance is a limited utterance among one or more pre-registered limited utterances, a risk determination unit that, in the case where the result of the determination is that the user utterance is not any one of the one or more pre-registered limited utterances, determines a risk of a process corresponding to the user utterance, and a process execution unit that, in the case where the risk of the process corresponding to the user utterance is not a low risk, outputs a guidance that prompts a user to make a limited utterance included in the pre-registered limited utterances are provided. In the case where the risk is not the low risk, the process execution unit outputs an alert including explanation information regarding the risk.
