Binaural sound source separation motivated by auditory processing
In this paper we present a new method of signal processing for robust speech recognition using two microphones. The method, loosely based on the human binaural hearing system, con...

Adapting acoustic and lexical models to dysarthric speech
Dysarthria is a motor speech disorder resulting from neurological damage to the part of the brain that controls the physical production of speech and is, in part, characterized by...

Phoneme and Sentence-Level Ensembles for Speech Recognition
We address the question of whether and how boosting and bagging can be used for speech recognition. In order to do this, we compare two different boosting schemes, one at the pho...

A VAD-robust Multichannel Wiener Filter algorithm for noise reduction in hearing aids
The Speech Distortion Weighted Multichannel Wiener Filter (SDWMWF) is a promising multi-microphone noise reduction technique, in particular for hearing aid applications. Its beneļ...

Learning non-parametric models of pronunciation
As more data becomes available for a given speech recognition task, the natural way to improve recognition accuracy is to train larger models. But, while this strategy yields mode...
