Voice Code Verification Algorithm Using Competing Models for User Entrance Authentication

Abstract

This work presents a voice-code verification system for an intelligent surveillance guard robot, wherein a robot prompts for a word or phrase for user entrance authentication. This system is designed to provide the text-prompted and speaker independent verification technique where a speaker dependent model cannot be obtained and the voice code can be changed every day for security reasoning. Experimental result showed that it brought about a 40% relative improvement under noisy environments.
