Voice-Based User Identification for Shared Query Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience in inputting account information for multiple services and security risks when using electronic devices, especially when multiple users share a device, and existing speech recognition technologies do not effectively utilize voice for user identification and personalized query recommendations.
Innovation Solution
An electronic device and system that utilize speech recognition to register and identify users based on voice, providing personalized query recommendations by checking user accounts and usage histories, and transmitting voice signals to a server for identification and processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users directly input account information for each service, then service access is achieved, but user convenience deteriorates due to repeated manual input
Solution Approach 1:
The system performs preliminary actions by capturing user account information through voice recognition in advance. The voice-based authentication pre-establishes user identity and retrieves usage history before service access is needed, eliminating the need for repeated manual account input across multiple services.
2Ease of operation
If users remain logged in to eliminate input inconvenience, then operation ease improves, but security deteriorates due to unauthorized access risks
Solution Approach 1:
The system replaces traditional mechanical authentication methods (password entry, cookie-based sessions) with voice recognition technology. Voice-based continuous authentication maintains security by verifying user identity through biometric voice patterns while keeping the system accessible, eliminating the need for users to remain continuously logged in with static credentials.
3Adaptability or versatility
If multiple users share one electronic device, then device utilization improves, but operation ease deteriorates due to repeated login requirements
Solution Approach 1:
The voice recognition system provides universal authentication that works across multiple user profiles and services. When multiple users share the device, each user's voice is uniquely identified and mapped to their account, enabling automatic authentication for all users without requiring manual login, thus making the authentication system universally applicable to all users of the device.
4Extent of automation
If speech recognition technology is implemented without voice-based user identification, then basic speech processing works, but user personalization capability deteriorates
Solution Approach 1:
The system implements feedback by using voice recognition to identify the user and then retrieving that user's specific usage history from stored data. This feedback loop personalizes the service by presenting queries and information tailored to the identified user's preferences and past behavior, transforming generic speech recognition into personalized user assistance.
Data Source
AI summary
An electronic device and a system including the same are disclosed. The electronic device according to one embodiment of the present disclosure comprises a display; a memory that stores a usage history; a user input interface that transmits signals corresponding to user inputs; and a controller, wherein the controller checks the user account corresponding to a voice signal when the voice signal is received through the user input interface, determines whether the usage history for the user account is stored in the memory, outputs a preset first recommended query through the display when the user account does not exist or the usage history for the user account does not exists in the memory, and outputs a second recommended query corresponding to the usage history for the user account through the display when the usage history for the user account is stored in the memory.
