Cluster and Intrinsic Dimensionality Analysis of the Modified Group Delay Feature for Speaker Classification
Speakers are generally identified by using features derived from the Fourier transform magnitude. The Modified group delay feature(MODGDF) derived from the Fourier transform phase has been used effectively for...

An Adaptive Non Reference Anchor Array Framework for Distant Speech Recognition
Distant speech recognition over microphone arrays is challenging, especially in multi source environments. In this paper, a non reference anchor array (NRA) framework for distant speech recognition is proposed...

Distant Speaker Verification Using a Combined Family of MVDR Estimates
Distant speaker verification involves explicit spectral estimation of speech acquired over microphone arrays. The choice of the appropriate set of microphones is important here. In this paper we describe an im...

An Unsupervised Approach to Multiple Speaker Tracking for Robust Multimedia Retrieval
Tagging multi media data based on who is speaking at what time, is important especially in the intelligent retrieval of recordings of meetings and conferences. In this paper an unsupervised approach to trackin...

Cosine Distance Metric Learning for Speaker Verification Using Large Margin Nearest Neighbor Method
In this paper, a novel cosine similarity metric learning based on large margin nearest neighborhood (LMNN) is proposed for an i-vector based speaker verification system. Generally, in an i-vector based speaker...

Client-wise cohort set selection by combining speaker- and phoneme-specific I-vectors for speaker verification
This work explores the use of phoneme level information in cohort selection to improve the performance of a speaker verification system. In speaker verification, cohort is used in score normalization to get a bet...
