Coordinator Device for Speech Recognition Wake-Up Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In environments where multiple electronic devices provide intelligent speech services, the wake-up of unintended devices due to a user's utterance leads to unnecessary operation loads and user inconvenience, as multiple devices enter a listening state and require manual switching.
Innovation Solution
An electronic device and method that receive information about a wake-up utterance from external devices, identify the optimal device to be woken up based on received information, and adjust time-out and priority values to minimize unnecessary device activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple electronic devices monitor for wake-up utterances in an environment, then the user can access speech services from any device, but unnecessary devices enter listening state causing operation load and user inconvenience
Solution Approach 1:
The patent introduces a coordinator device that acts as an intermediary to manage wake-up utterance monitoring across multiple electronic devices. The coordinator receives wake-up utterances, determines the appropriate target device, and activates only that specific device. This mediator approach maintains service accessibility while preventing unnecessary devices from entering listening state, thus reducing overall operation load.
Solution Approach 2:
The system performs preliminary determination of the target device before activating the listening state. The coordinator device identifies which device should respond to the wake-up utterance based on pre-configured device information and user context, then activates only that specific device. This preliminary action prevents other devices from unnecessarily entering listening state.
2Adaptability or versatility
If multiple electronic devices enter listening state upon wake-up utterance, then speech service availability is maximized, but user convenience deteriorates due to need for manual switching
Solution Approach 1:
The coordinator device serves as an intermediary that automatically determines the appropriate target device for each wake-up utterance based on pre-stored device information and user context. This automated mediation eliminates the need for users to manually switch between devices, improving ease of operation while maintaining speech service availability.
Solution Approach 2:
The system implements self-service by automatically identifying and activating the appropriate device without requiring user intervention for device switching. The coordinator device uses pre-configured information to autonomously determine which device should handle the wake-up utterance, making the system self-organizing and user-friendly.
3Reliability
If all electronic devices continuously monitor for wake-up utterances, then response coverage is improved, but energy consumption increases
Solution Approach 1:
The coordinator device acts as an energy-efficient intermediary by receiving and processing wake-up utterances centrally. Instead of all devices continuously monitoring, the coordinator handles the wake-up detection and routing, allowing other devices to remain in lower-power states. This maintains response coverage while significantly reducing overall energy consumption.
Solution Approach 2:
The system performs preliminary wake-up utterance processing at the coordinator device before activating the target device. This preliminary action allows the coordinator to identify and activate only the necessary device, keeping other devices in low-power states and reducing overall energy consumption while maintaining reliable response coverage.
