Voice Recognition System Using Packet Buffering and Third-Party Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Voice authentication systems over fixed networks incur significant infrastructure costs and exclude individuals without access to phone lines, and they are inefficient over packet-switched networks like the Internet.
Innovation Solution
A method and system for voice recognition that receives packetized voice data over a packet-switched network, waits for sufficient data to ensure a verifiable comparison, and uses a third-party verification system to authenticate users, minimizing costs for secure service providers and enabling access for those without traditional phone lines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If voice authentication is conducted over a fixed telephone network, then authentication reliability is improved, but infrastructure cost increases and accessibility decreases
Solution Approach 1:
The patent introduces a third-party verification system as an intermediary between the user and the secure service provider. This mediator handles the voice authentication process, allowing the service provider to outsource authentication infrastructure costs while maintaining security. The third-party system receives voice data packets, performs verification, and returns results, thus resolving the contradiction between reliability and infrastructure cost.
2Adaptability or versatility
If voice data is transmitted over packet-switched networks, then accessibility is improved, but data loss increases
Solution Approach 1:
The patent implements a buffering mechanism that waits for a predetermined number of voice data packets to be received before initiating the authentication process. This preliminary action ensures that sufficient data is accumulated to compensate for packet loss inherent in packet-switched networks, while still allowing the system to operate over accessible internet connections rather than requiring dedicated phone lines.
3Speed
If voice authentication is performed in real-time, then processing speed is improved, but accuracy decreases due to insufficient data
Solution Approach 1:
The system performs preliminary data collection by buffering incoming voice packets until a sufficient quantity is accumulated. This preliminary action ensures that the voice comparison process has adequate data for accurate analysis, while the automated buffering process minimizes the time delay. The system thus balances speed and accuracy by preparing data in advance rather than processing prematurely.
Data Source
AI summary
The present invention relates to a method of providing voice recognition. The method comprises the steps of receiving a packetised voice data of a person to be identified over a packet-switched network, comparing the voice data with a stored voice data of a user and, based on the comparison, providing an indication of the likelihood that the person to be identified is the user, wherein the step of receiving the voice data comprises waiting for sufficient voice data to be received.
