The Clarity & Cadenza Challenges (2024)
Journal Article
Akeroyd, M., Bailey, W., Bannister, S., Firth, J., Graetzer, S., Roa Dabike, G., …Research Project, C. (in press). The Clarity & Cadenza Challenges. #Journal not on list, 1209-1211. https://doi.org/10.61782/fa.2023.0876

Clarity (Speech in noise) and Cadenza (music) are two EPSRC projects that are exploiting the latest in machine learning to create improved listening experiences for those with a hearing loss. In both we are running a series of open competitions, for... Read More about The Clarity & Cadenza Challenges.

Overview of the 2023 ICASSP SP Clarity Challenge: Speech Enhancement for Hearing Aids (2023)
Journal Article
Cox, T. J., Barker, J., Bailey, W., Graetzer, S., Akeroyd, M. A., Culling, J. F., & Naylor, G. (2023). Overview of the 2023 ICASSP SP Clarity Challenge: Speech Enhancement for Hearing Aids. Proceedings of the ... IEEE International Conference on Acoustics, Speech, and Signal Processing (Online), https://doi.org/10.1109/icassp49357.2023.10433922

This paper reports on the design and outcomes of the ICASSP SP Clarity Challenge: Speech Enhancement for Hearing Aids. The scenario was a listener attending to a target speaker in a noisy, domestic environment. There were multiple interferers and hea...

Dataset of British English speech recordings for psychoacoustics and speech processing research : the Clarity Speech Corpus (2022)
Journal Article
Graetzer, S., Akeroyd, M., Barker, J., Cox, T., Culling, J., Naylor, G., …Muñoz, R. (2022). Dataset of British English speech recordings for psychoacoustics and speech processing research : the Clarity Speech Corpus. Data in Brief, 41, 107951. https://doi.org/10.1016/j.dib.2022.107951

This paper presents the Clarity Speech Corpus, a publicly available, forty speaker British English speech dataset. The corpus was created for the purpose of running listening tests to gauge speech intelligibility and quality in the Clarity Project, w...

Clarity-2021 challenges : machine learning challenges for advancing hearing aid processing (2021)
Journal Article
Graetzer, S., Barker, J., Cox, T., Akeroyd, M., Culling, J., Naylor, G., …Viveros Munoz, R. (2021). Clarity-2021 challenges : machine learning challenges for advancing hearing aid processing. https://doi.org/10.21437/Interspeech.2021-1574

In recent years, rapid advances in speech technology have been made possible by machine learning challenges such as CHiME, REVERB, Blizzard, and Hurricane. In the Clarity project, the machine learning approach is applied to the problem of hearing aid...

A set of equations for numerically calculating the interaural level difference in the horizontal plane (2021)
Journal Article
Akeroyd, M. A., Firth, J., Graetzer, S., & Smith, S. (2021). A set of equations for numerically calculating the interaural level difference in the horizontal plane. JASA Express Letters, 1(4), 044402. https://doi.org/10.1121/10.0004261

The variation of interaural level difference (ILD) with direction and frequency is particularly complex and convoluted. The purpose of this work was to determine a set of parametric equations that can be used to calculate ILDs continuously at any val...

Intelligibility prediction for speech mixed with white Gaussian noise at low signal-to-noise ratios (2021)
Journal Article
Graetzer, S., & Hopkins, C. (2021). Intelligibility prediction for speech mixed with white Gaussian noise at low signal-to-noise ratios. ˜The œJournal of the Acoustical Society of America (Online), 149(2), 1346-1362. https://doi.org/10.1121/10.0003557

The effect of additive white Gaussian noise and high-pass filtering on speech intelligibility at signal-to-noise ratios (SNRs) from -26 to 0 dB was evaluated using British English talkers and normal hearing listeners. SNRs below -10 dB were considere... Read More about Intelligibility prediction for speech mixed with white Gaussian noise at low signal-to-noise ratios.
