Smart Home Voiceprint Control for User-Specific Operating Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current smart home systems lack the ability to differentiate between users, resulting in limited control options and a poor user experience, as they can only perform simple tasks like turning devices on or off through voice commands without considering individual preferences or settings.
Innovation Solution
A smart home control method that identifies users based on biological information such as voiceprint, face image, or fingerprint features, allowing for personalized operating modes and settings for each family member, enabling more complex control sequences and energy-efficient operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice control is used for smart home devices, then the device can be controlled remotely, but the control functionality is limited to simple operations only
Solution Approach 1:
The system segments control functionality by user identity, creating separate control profiles for different family members. Each profile contains personalized operating parameters and control sequences, allowing the same voice command to trigger different device configurations based on who is speaking.
Solution Approach 2:
The control system dynamically adapts its behavior based on real-time voiceprint identification. When a user speaks, the system identifies their voiceprint and automatically loads their personalized control profile, making the system's functionality dynamic rather than static.
2Device complexity
If a single control profile is used for all users, then the system is simple to implement, but it cannot reflect individual user preferences and settings
Solution Approach 1:
The control profile is segmented into multiple user-specific profiles stored in the server. Each profile contains customized operating parameters for smart home devices. The system maintains simplicity by using a unified profile structure that is replicated for each user, rather than creating entirely different control mechanisms.
Solution Approach 2:
The voice control system serves multiple functions: it acts as both the control interface and the identification mechanism. The same voice command structure is used for all users, but the system universally applies different personalized profiles based on voiceprint matching, making the identification system multi-functional.
3Ease of operation
If voice control is implemented, then users can control devices without physical contact, but the system cannot distinguish between different users
Solution Approach 1:
The system incorporates feedback through voiceprint analysis. When a user issues a voice command, the server analyzes the voiceprint characteristics and provides feedback by selecting the appropriate user profile. This feedback mechanism enables accurate user distinction while maintaining contactless control.
Solution Approach 2:
The system replaces physical identification methods (such as cards, passwords, or biometric scanners) with acoustic field-based voiceprint identification. This substitution maintains the contactless advantage while adding user distinction capability through voice characteristic analysis.

AI summary
A central control device identifies an identity of a user, and determines, based on the identity of the user, a smart home linkage solution associated with the identity of the user. Then, the central control device controls, based on the smart home linkage solution associated with the identity of the user, a public smart home device to enter a corresponding operating mode. When receiving a first operation of the user, the central control device controls, based on the smart home linkage solution associated with the identity of the user, the public smart home device to enter the corresponding operating mode.
