A data-driven post-filter design based on spatially and temporally smoothed a priori SNR
A microphone array beamformer combined with a post-filter estimation based on spatial smoothing can deliver good noise attenuation preserving the speech component, however, with ...

Quantifying perturbations in temporal dynamics for automated assessment of spastic dysarthric speech intelligibility
Spastic dysarthric speech is often associated with imprecise placement of articulators which, in turn, cause perturbations in speech temporal dynamics, such as unclear distinction...

Template-based methods for sentence generation and speech synthesis
Here we propose a sentence-generation method using templates that can be applied to create a speech database. This method requires the recording of a relatively small sentence set...

A multistage approach to blind separation of convolutive speech mixtures
We propose a novel algorithm for the separation of convolutive speech mixtures using two-microphone recordings, based on the combination of independent component analysis (ICA) an...

On the use of ideal binary masks for improving phonetic classification
Ideal binary masks are binary patterns that encode the masking characteristics of speech in noise. Recent evidence in speech perception suggests that such binary patterns provide ...
