Visual Speech Benefit in Clear and Degraded Speech Depends on the Auditory Intelligibility of the Talker and the Number of Background Talkers (2019)
Journal Article
Blackburn, C. L., Kitterick, P. T., Jones, G., Sumner, C. J., & Stacey, P. C. (2019). Visual Speech Benefit in Clear and Degraded Speech Depends on the Auditory Intelligibility of the Talker and the Number of Background Talkers. Trends in Hearing, 23, 1-14. https://doi.org/10.1177/2331216519837866

Perceiving speech in background noise presents a significant challenge to listeners. Intelligibility can be improved by seeing the face of a talker. This is of particular value to hearing impaired people and users of cochlear implants. It is well kno...

Mammalian behavior and physiology converge to confirm sharper cochlear tuning in humans (2018)
Journal Article
Sumner, C. J., Wells, T., Bergevin, C., Sollini, J., Kreft, H., Palmer, A., …Shera, C. (2018). Mammalian behavior and physiology converge to confirm sharper cochlear tuning in humans. Proceedings of the National Academy of Sciences, 115(44), 11322-11326. https://doi.org/10.1073/pnas.1810766115

© 2018 National Academy of Sciences. All rights reserved. Frequency analysis of sound by the cochlea is the most fundamental property of the auditory system. Despite its importance, the resolution of this frequency analysis in humans remains controve...

Changes in neuronal representations of consonants in the ascending auditory system and their role in speech recognition (2018)
Journal Article
Steadman, M. A., & Sumner, C. J. (2018). Changes in neuronal representations of consonants in the ascending auditory system and their role in speech recognition. Frontiers in Neuroscience, 12, Article 671. https://doi.org/10.3389/fnins.2018.00671

A fundamental task of the ascending auditory system is to produce representations that facilitate the 11 recognition of complex sounds. This is particularly challenging in the context of acoustic variability, 12 such as that between different talkers...

Revisiting models of concurrent vowel identification: the critical case of no pitch differences (2018)
Journal Article
Smith, S. S., Chintanpalli, A., Heinz, M. G., & Sumner, C. J. (2018). Revisiting models of concurrent vowel identification: the critical case of no pitch differences. Acta Acustica united with Acustica, 104(5), 922-925. https://doi.org/10.3813/AAA.919244

When presented with two vowels simultaneously, humans are often able to identify the constituent vowels. Computational models exist that simulate this ability, however they predict listener confusions poorly, particularly in the case where the two vo...

Spatial processing is frequency specific in auditory cortex but not in the midbrain (2017)
Journal Article
Mill, R., Sumner, C. J., & Sollini, J. A. (2017). Spatial processing is frequency specific in auditory cortex but not in the midbrain. Journal of Neuroscience, 37(27), 6588-6599. https://doi.org/10.1523/JNEUROSCI.3034-16.2017

© 2017 the authors. The cochlea behaves like a bank of band-pass filters, segregating information into different frequency channels. Some aspects of perception reflect processing within individual channels, but others involve the integration of infor...

Relating approach-to-target and detection tasks in animal psychoacoustics (2016)
Journal Article
Sumner, C., Sollini, J., & Alves-Pinto, A. (2016). Relating approach-to-target and detection tasks in animal psychoacoustics. Behavioral Neuroscience, 130(4), 393-405. https://doi.org/10.1037/bne0000143

Psychophysical experiments seek to measure the limits of perception. While straightforward in humans, in animals they are time consuming. Choosing an appropriate task and interpreting measurements can be challenging. We investigated the localization...

The contribution of visual information to the perception of speech in noise with and without informative temporal fine structure (2016)
Journal Article
Stacey, P. C., Kitterick, P. T., Morris, S. D., & Sumner, C. J. (2016). The contribution of visual information to the perception of speech in noise with and without informative temporal fine structure. Hearing Research, 336, 17-28. https://doi.org/10.1016/j.heares.2016.04.002

Understanding what is said in demanding listening situations is assisted greatly by looking at the face of a talker. Previous studies have observed that normal-hearing listeners can benefit from this visual information when a talker’s voice is presen...

Behavioural estimates of auditory filter widths in ferrets using notched-noise maskers (2016)
Journal Article
Sumner, C., Alves-Pinto, A., Sollini, J., & Wells, T. (2016). Behavioural estimates of auditory filter widths in ferrets using notched-noise maskers. Journal of the Acoustical Society of America, 139(2), EL19-EL24. https://doi.org/10.1121/1.4941772

Frequency selectivity is a fundamental property of hearing which affects almost all aspects of auditory processing. Here auditory filter widths at 1, 3, 7, and 10 kHz were estimated from behavioural thresholds using the notched-noise method [Patterso...

Searching for a talking face: The effect of degrading the auditory signal (2014)
Journal Article
Stacey, P. C., Murphy, T., Sumner, C. J., Kitterick, P. T., & Roberts, K. L. (2014). Searching for a talking face: The effect of degrading the auditory signal. Journal of Experimental Psychology: Human Perception and Performance, 40(6), 2106-2111. https://doi.org/10.1037/a0038220

Previous research (e.g., McGurk & MacDonald, 1976) suggests that faces and voices are bound automatically, but recent evidence suggests that attention is involved in a task of searching for a talking face (Alsius & Soto-Faraco, 2011). We hypothesized... Read More about Searching for a talking face: The effect of degrading the auditory signal.
