Text-independent speaker verification using virtual speaker based cohort normalization

In this paper, we propose a new score normalization method for text-independent speaker verification using GMM (Gaussian Mixture Model). In the proposed method, cohort model is designed as virtual speaker model based on the similarity of local acoustic information between the reference speaker and other customers. The similarity is determined using statistical distance between model components ...

On cohort selection for speaker verification

Speaker verification systems require some kind of background model to reliably perform the verification task. Several algorithms have been proposed for the selection of cohort models to form a background model. This paper proposes a new cohort selection method called the Close Impostor Clustering (CIC). The new method is shown to outperform several other methods in a text-dependent verification...

presenting a new text-independent speaker verification system based on multi model gmm

speaker verification is the process of accepting or rejecting claimed identity in terms of its sound features. a speaker verification system can be used for numerous security systems, including bank account accessing, getting to security points, criminology and etc. when a speaker verification system wants to check the identity of individuals remotely, it confronts problems such as noise effect...

Information based Speaker Verification

We discuss in this paper the conceptual and compu­ tational framework.of informatzon theory for decision making in speaker verification. The proposed approach departs itself from other conventional scoring models for speaker verification as the first approach takes into account the quantity of 'surprise' or information con­ tent. We compare the new approach with a widely used log-likelihood nor...

Best speaker-based structure tree for speaker verification

In this paper we study the use of the Wavelet transform for textdependent speaker verification purposes. A new algorithm to construct the best admissible tree is proposed which has been used to obtain a speaker dependent tree library. Every tree in this library corresponds to the best structure for a given speaker, therefore the extracted parameters from a given tree are well suited and discrim...
