Voice Control Terminal Using Voiceprint Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current voice recognition systems in terminals lack effective methods to securely differentiate between authorized and unauthorized voice commands, leading to potential privacy and security issues.
Innovation Solution
The system matches voice information in voice instructions with preset voice information, using frequency, pitch, and timbre analysis to authenticate commands, and displays corresponding visual animations for successful or unsuccessful matches, ensuring only authorized users can control the terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice recognition is applied to terminal functions, then user interaction convenience is improved, but security and privacy protection deteriorate
Solution Approach 1:
The patent segments voice recognition into two distinct functions: general voice assistant operations and authorized voice control operations. By separating these functions and applying different authentication requirements, the system maintains convenience for general tasks while ensuring security for sensitive operations.
Solution Approach 2:
The patent implements preliminary voiceprint authentication before enabling voice control functions. The terminal pre-stores the user's voiceprint information and requires matching this stored data against incoming voice commands, ensuring that only authorized users can execute control operations.
2Reliability
If voiceprint authentication is implemented, then security is improved, but system complexity increases
Solution Approach 1:
The patent implements self-service voiceprint authentication where the terminal automatically extracts voiceprint features from incoming voice commands and compares them against stored templates without requiring manual intervention. The system autonomously determines authentication results and executes appropriate actions, reducing operational complexity.
Solution Approach 2:
The patent replaces traditional mechanical authentication methods (such as passwords or physical keys) with acoustic field-based voiceprint recognition. This substitution leverages the uniqueness of human voice characteristics to provide security without requiring complex physical security mechanisms.
3Reliability
If voice information matching is performed, then unauthorized access is prevented, but processing time increases
Solution Approach 1:
The patent applies partial matching by comparing only critical voiceprint features rather than performing exhaustive analysis of the entire voice signal. By focusing on key authentication parameters, the system achieves sufficient security verification while minimizing processing time and computational resources required.
Data Source
AI summary
The application relates to a terminal and method for voice control on a terminal. A terminal according to some embodiments of the application includes: one or more processors, and a memory, wherein, the memory stores therein one or more computer readable program codes, and the processor or processors are configured to execute the one or more computer readable program codes, to match voice information in a voice instruction with preset voice information in the terminal upon reception of the voice instruction comprising the voice information and instruction information, to perform an operation corresponding to the instruction information upon determining successful matching, and to reject the operation corresponding to the instruction information upon determining unsuccessful matching.
