Method and system for voice operating at least one electronic device, especially a household domestic appliance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice control methods for household appliances only adapt standard control commands based on the user's individual profile, failing to account for preferences of other individuals or situations where no user profile is assigned.
Innovation Solution
The method detects signal words in voice commands to select and apply user profiles, allowing for adaptive control commands based on stored information, even if no specific profile exists, and utilizes speech recognition and a server-based system for cost-effective implementation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If voice control adapts only to the speaking user's profile, then the control is personalized for the speaker, but it cannot accommodate preferences of other individuals or situations without user profiles
Solution Approach 1:
The system segments user identification into two independent components: voice biometric recognition for speaker identification and signal word detection for explicit user profile selection. This segmentation allows the system to handle cases where the speaker and the intended user differ, resolving the contradiction between personalization and multi-user support.
Solution Approach 2:
Signal words act as an intermediary mechanism between the voice command and user profile selection. Instead of directly linking voice biometrics to user profiles, the signal word serves as a mediator that explicitly specifies which user profile should be applied, enabling flexible user profile selection independent of the speaker's identity.
2Adaptability or versatility
If multiple user profiles are supported with explicit selection, then the system can accommodate different users' preferences, but the voice command structure becomes more complex
Solution Approach 1:
The system employs self-service through automatic signal word detection and user profile selection. Instead of requiring users to manually navigate complex profile selection interfaces or remember specific profile identifiers, the system automatically detects signal words in the voice command and selects the appropriate user profile, maintaining ease of operation while supporting multiple profiles.
Solution Approach 2:
The system changes the parameter of user profile selection from implicit (based solely on voice biometrics) to explicit (based on detected signal words). This parameter change allows the system to support multiple user profiles while maintaining intuitive operation, as users can simply mention another person's name or a profile identifier in their voice command without needing to understand the underlying system complexity.

AI summary
The invention relates to a method for voice control of at least one electronic device, in particular a household appliance, wherein a voice command is detected by means of a voice input device and the voice command is monitored for a standard control command. It is provided that the voice command is monitored for signal words, that upon detection of a signal word a stored user profile is selected depending on the detected signal word, and that the electronic device is controlled depending on the standard control command on the one hand and on information contained in the selected user profile on the other.
