Kernel Based Text-independnent Speaker Verification
The goal of a person authentication system is to authenticate the claimed identity of a user. When this authentication is based on the voice of the user, without respect of what the user exactly said, the system is called a text-independent speaker verification system. Speaker verification systems are increasingly often used to secure personal information, particularly for mobile phone based ap...
متن کاملKernel Alignment Maximization for Speaker Recognition Based on High-Level Features
In this paper text-independent automatic speaker verification based on support vector machines is considered. A generalized linear kernel training method based on kernel alignment maximization is proposed. First, kernel matrix decomposition into a sum of maximally aligned directions in the input space is performed and this decomposition is spectrally optimized. The method was evaluated for high...
متن کاملA kernel trick for sequences applied to text-independent speaker verification systems
This paper present a principled SVM based speaker verification system. We propose a new framework and a new sequence kernel that can make use of any Mercer kernel at the frame level. An extension of the sequence kernel based on the Max operator is also proposed. The new system is compared to state-of-the-art GMM and other SVM based systems found in the literature on the Banca and Polyvar databa...
متن کاملText-Independent Speaker Verification via State Alignment
To model the speech utterance at a finer granularity, this paper presents a novel state-alignment based supervector modeling method for text-independent speaker verification, which takes advantage of state-alignment method used in hidden Markov model (HMM) based acoustic modeling in speech recognition. By this way, the proposed modeling method can convert a text-independent speaker verification...
متن کاملCompensations for SVM in Text-Independent Speaker Verification
Support Vector Machines (SVMs) technique, as a kind of pattern classifier, is widely used in pattern classification including speaker verification. We study the asymmetrical character of speaker verification that uses SVM since the asymmetry between true and imposter speaker training sets degrade recognition rate. Asymmetrical costs kernel is implemented and based on it, we introduce a new meth...
