This paper describes a new framework for designing speaker recognition systems based on the discriminative feature extraction (DFE) method. We apply a mel-cepstral estimation technique to the feature extractor in a Gaussian mixture model (GMM)-based text-independent speaker identification system. The mel-cepstral estimation technique uses the second-order all-pass warping function for frequency...

This paper proposes a novel technique of incorporating factor-analysis-based inter-session variability (ISV) modelling in speaker verification systems that employ continuous progressive speaker model adaptation. Continuous model adaptation involves the use of all encountered trials in the adaptation process through the assignment of confidence measures. The proposed approach incorporates these ...

Recently many research has been conducted to retrieve pertinent parameters and adequate models for automatic music genre classification. In this paper, two measures based upon information theory concepts are investigated for mapping the features space to decision space. A Gaussian Mixture Model (GMM) is used as a baseline and reference system. Various strategies are proposed for training and te...

The contribution of this paper is to analyse the role of network interdependencies in a dynamic panel data model for German internal migration fl ows since re-unifi cation. So far, a capacious account of spatial patterns in German migration data is still missing in the empirical literature. In the context of this paper, network dependencies are associated with correlations of migration fl ows s...

In this letter, we present a speech enhancement technique based on the ambient noise classification incorporating the Gaussian mixture model (GMM). The principal parameters of the statistical model-based speech enhancement algorithm such as the weighting parameter in the decision-directed (DD) method and the long-term smoothing parameter of the noise estimation, are chosen as different values a...

In stock markets, information plays a crucial role in determining trading dynamics and price discovery. the investment decisions, an investor may have incomplete regarding firm-specific factors because of asymmetry. Therefore, investors rely on market factors. Extensive work has been done synchronicity (SYNCH) from dual banking system viewpoint. present study examines association Stock Price Sy...
