Context-Aware Voice Command Reception Without Wake Words
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice-enabled devices require users to perform actions like uttering a wake word or pressing a button for voice command recognition, which is troublesome and burdensome.
Innovation Solution
An information processing device that determines the appropriate situation and automatically enables voice command reception without user action, using sensors and external apparatuses to identify the context and inform the user of receivable commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a user action (uttering wake word or pressing button) is required to activate voice command reception, then false recognition is prevented, but user convenience deteriorates due to the troublesome and burdensome nature of performing actions every time
Solution Approach 1:
The system automatically determines situations using sensors and external apparatuses without requiring user activation actions. The voice command reception is automatically enabled or disabled based on the determined situation, making the system serve itself by autonomously managing its operational state according to contextual information.
Solution Approach 2:
The system performs preliminary situation determination before voice command reception is activated. By pre-assessing the situation using sensors and external apparatuses, the system prepares the appropriate reception state in advance, eliminating the need for user activation actions while maintaining controlled recognition.
2Ease of operation
If voice command reception is always enabled without user action, then user convenience is improved, but false recognition increases due to unintended command activation
Solution Approach 1:
The voice command reception state is dynamically adjusted based on the determined situation. The system transitions between enabled and disabled states according to contextual information from sensors and external apparatuses, making the reception capability flexible and adaptive rather than static or always-on.
Solution Approach 2:
The system changes the operational parameter of voice command reception (enabled/disabled state) based on situation determination. By modifying this parameter according to contextual conditions, the system achieves both convenience (automatic activation when appropriate) and reliability (prevention of false recognition when inappropriate).

AI summary
A user is assisted in performing a voice operation appropriately.A situation determination section determines a situation. A state control section controls a voice command appropriate for the determined situation to put the voice command into a receivable state. For example, the user is informed of what the voice command in a receivable state is, by means of display or voice output. The user can utter a voice command without performing a user action to prevent false recognition, such as the utterance of a wake word. This reduces the troublesomeness and burden of the user.
