Probabilistic Linear Discriminant Analysis for Acoustic Modelling
In this letter, we propose a new acoustic modelling approach for automatic speech recognition based on probabilistic linear discriminant analysis (PLDA), which is used to model the state density function for the standard hidden Markov models (HMMs). Unlike the conventional Gaussian mixture models (GMMs) where the correlations are weakly modelled by using the diagonal covariance matrices, PLDA c...
متن کاملJoint Probabilistic Linear Discriminant Analysis
Standard probabilistic linear discriminant analysis (PLDA) for speaker recognition assumes that the sample’s features (usually, i-vectors) are given by a sum of three terms: a term that depends on the speaker identity, a term that models the within-speaker variability and is assumed independent across samples, and a final term that models any remaining variability and is also independent across...
متن کاملFeature-space speaker adaptation for probabilistic linear discriminant analysis acoustic models
Probabilistic linear discriminant analysis (PLDA) acoustic models extend Gaussian mixture models by factorizing the acoustic variability using state-dependent and observationdependent variables. This enables the use of higher dimensional acoustic features, and the capture of intra-frame feature correlations. In this paper, we investigate the estimation of speaker adaptive feature-space (constra...
متن کاملSparse Probabilistic Linear Discriminant Analysis for Speaker Verification
This paper introduces an approach based on a generative model named Sparse Probabilistic Linear Discriminant Analysis in speaker verification. The model provides an alternative approach to deal with the non-Gaussian behavior of the latent variables, directly assuming they are based on Laplace prior. This distribution encourages the model to set many latent variables to zero. An expectation-maxi...
متن کاملTied Probabilistic Linear Discriminant Analysis for Speech Recognition
Acoustic models using probabilistic linear discriminant analysis (PLDA) capture the correlations within feature vectors using subspaces which do not vastly expand the model. This allows high dimensional and correlated feature spaces to be used, without requiring the estimation of multiple high dimension covariance matrices. In this letter we extend the recently presented PLDA mixture model for ...
