Voice Recognition Wait Time Context Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current voice recognition systems in electronic devices require a wake-up word for activation, which is inconvenient, especially in hands-free or far-field situations, and necessitate repeated utterance of the wake-up word and redundant commands for task execution.
Innovation Solution
An electronic device with a processor configured to detect a wake-up word, process a first task, set a wait time, detect a second voice command during this time, analyze the conversational context, and process subsequent tasks without requiring a wake-up word or redundant commands, allowing continuous voice recognition service based on previous conversational context.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wake-up word method is used to activate voice recognition service, then the service can be reliably triggered, but the user must inconveniently utter the wake-up word repeatedly for each task
Solution Approach 1:
The system performs preliminary action by activating the voice recognition service in advance through a wake-up word, then maintains the service in an active state during a wait time period. This allows subsequent voice commands to be processed without requiring repeated wake-up words, thus resolving the contradiction between reliable activation and operational convenience.
2Ease of operation
If voice recognition service is continuously active to respond to follow-up commands, then operational convenience is improved, but energy consumption increases
Solution Approach 1:
The system implements periodic action by activating the voice recognition service temporarily for a specific wait time duration after detecting a wake-up word. The service is active only during this period to process follow-up commands, then deactivated. This periodic activation pattern resolves the contradiction between continuous operation convenience and energy consumption.
3Reliability
If the system requires wake-up word for each task, then service activation is controlled, but productivity decreases due to repeated utterances
Solution Approach 1:
The system maintains continuity of useful action by keeping the voice recognition service active during a wait time period after wake-up word detection. This allows multiple voice commands to be processed continuously without requiring repeated wake-up words, thereby improving task execution efficiency while maintaining controlled service activation through the initial wake-up trigger.
