Voice Recognition Device Priority Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In environments where multiple electronic devices with voice recognition capabilities are present, there is a challenge in ensuring that voice commands are accurately directed to the intended device, leading to unintended activation of multiple devices and confusion.
Innovation Solution
An electronic apparatus and method that determine which device to perform voice recognition based on priority and user intention by using a wake-up word, where only the device with the highest priority performs voice recognition, and other devices remain inactive, utilizing a communicator to share voice recognition information and control commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple electronic devices with voice recognition capabilities are present in one space, then voice recognition functionality is available in all devices, but multiple devices may be simultaneously activated causing confusion and unintended actions
Solution Approach 1:
The patent assigns different priority levels to different electronic devices, creating local quality differences in their voice recognition activation characteristics. Devices with higher priority are more likely to be activated for voice recognition, while lower priority devices remain inactive unless higher priority devices are unavailable. This resolves the contradiction by maintaining versatility across multiple devices while ensuring reliable command execution through priority-based selection.
2Ease of operation
If all electronic devices perform voice recognition simultaneously, then user can interact with any device, but it causes confusion about which device should execute the command
Solution Approach 1:
The system provides feedback to the user about which device is selected to perform voice recognition and execute commands. This feedback mechanism maintains ease of operation by allowing users to interact with any device while preventing information loss about device selection clarity, as users can see which device is currently active for voice recognition.
3Reliability
If priority-based device selection is implemented, then command execution accuracy is improved, but system complexity increases due to priority management
Solution Approach 1:
The system performs preliminary action by pre-establishing priority relationships between devices before voice recognition is needed. Devices are assigned priority levels in advance, so when a voice command is given, the system can quickly determine which device should execute it without complex real-time decision-making. This reduces the apparent complexity during operation while maintaining high command execution accuracy.

AI summary
Selectively performing voice recognition using one device among multiple devices that recognize and execute the voice recognition based on at least one of apparatus information of the multiple devices and a function parsed from a result of the voice recognition. Thereby, only a single preferable device in an environment in which multiple devices exist, which can service the user input via voice recognition, actually responds to the voice input and services the voice input of the user. This includes a method for voice recognition in an electronic apparatus, the method comprising:performing a voice recognition corresponding to a voice input; identifying a target apparatus based on at least one from among apparatus information and function information included in a result of the performed voice recognition; and transmitting a control command corresponding to the voice recognition result to the target apparatus.
