with humans through speech has become plausible today due to rapid strides in efficient …

On the issues of intra-speaker variability and realism in speech, speaker, and language recognition tasks

JHL Hansen, H Bořil - Speech Communication, 2018 - Elsevier
Recent years have witnessed notable advancements in the areas of speech, speaker and
language/dialect recognition. However, many of the emerging scientific principles appear to …

Spectral and temporal changes to speech produced in the presence of energetic and informational maskers

M Cooke, Y Lu - The Journal of the Acoustical Society of America, 2010 - pubs.aip.org
Talkers change the way they speak in noisy conditions. For energetic maskers, speech
production changes are relatively well-understood, but less is known about how …

Unsupervised equalization of Lombard effect for speech recognition in noisy adverse environments

H Boril, JHL Hansen - IEEE Transactions on Audio, Speech …, 2009 - ieeexplore.ieee.org
In the presence of environmental noise, speakers tend to adjust their speech production in
an effort to preserve intelligible communication. The noise-induced speech adjustments …

The intelligibility of Lombard speech for non-native listeners

M Cooke, MLG Lecumberri - The Journal of the Acoustical Society of …, 2012 - pubs.aip.org
Speech produced in the presence of noise—Lombard speech—is more intelligible in noise
than speech produced in quiet, but the origin of this advantage is poorly understood. Some …

Generative modeling of pseudo-whisper for robust whispered speech recognition

S Ghaffarzadegan, H Bořil… - IEEE/ACM Transactions …, 2016 - ieeexplore.ieee.org
Whisper is a common means of communication used to avoid disturbing individuals or to
exchange private information. As a vocal style, whisper would be an ideal candidate for …

The impact of task automaticity on speech in noise

AP Vogel, J Fletcher, P Maruff - Speech Communication, 2014 - Elsevier
In the control of skeleto-motor movement, it is well established that the less complex, or more
automatic a motor task is, the less variability and uncertainty there is in its performance. It …

UT-VOCAL EFFORT II: Analysis and constrained-lexicon recognition of whispered speech

S Ghaffarzadegan, H Bořil… - 2014 IEEE International …, 2014 - ieeexplore.ieee.org
This study focuses on acoustic variations in speech introduced by whispering, and proposes
several strategies to improve robustness of automatic speech recognition of whispered …

Comparing the consistency and distinctiveness of speech produced in quiet and in noise

J Kim, C Davis - Computer Speech & Language, 2014 - Elsevier
The study investigated whether properties of speech produced in noise (Lombard speech)
were more distributed (thus potentially more distinct) and/or more consistent than those from …

UT-Scope: Towards LVCSR under Lombard effect induced by varying types and levels of noisy background

H Bořil, JHL Hansen - 2011 IEEE International Conference on …, 2011 - ieeexplore.ieee.org
Adverse environments impact the performance of automatic speech recognition systems in
two ways-directly by introducing acoustic mismatch between the speech signal and acoustic …
