The 4th Clarity Workshop on Machine Learning Challenges for Hearing Aids (Clarity-2023) will be held as an official ISCA satellite event of Interspeech-2023 and will be a one-day event held on 19th August 2023 in Dublin, Ireland.

Any work related to the challenges of hearing aid signal processing will be considered relevant. Topics include, but are not limited to:

  • Binaural technology for speech enhancement and source separation
  • Multi-microphone processing technology
  • Real-time approaches to speech enhancement
  • Statistical model-driven approaches to hearing aid processing
  • Audio quality & intelligibility assessment hearing aid and cochlear implant users
  • Efficient and effective integration of psychoacoustic testing in machine learning
  • Machine learning for diverse target listeners
  • Machine learning models of hearing impairment

The workshop will also be hosting the 2nd Clarity Prediction Challenge (CPC2) and will provide a forum for the presentation of the results.

Important Dates

  • Mid April - Workshop registration opens
  • 2nd June - Submission deadline for regular workshop papers
  • 31st July - Submission deadline for CPC2 papers
  • 19th August - ISCA Clarity 2023 workshop @ Interspeech

The programme will consist of a mix of oral and poster presentations, panel discussions and keynote talks. For full details please visit the workshop website:

The 2nd round of the Clarity Prediction Challenge (CPC2) has now been launched. This builds on the first challenge by using more complex signals and a larger set of listening test data for training and evaluating the prediction systems.

The outputs of the new challenge will be presented at an the ISCA Clarity-2023 workshop that is being run as a satellite event to Interspeech 2023 in Dublin on 19th August 2023.

Full details can be found on the Challenge Website.

Register now to take part

If you are interested in participating please register now via the online registration form.

Important Dates

  • March - Launch of challenge, release of training data + baseline system.
  • 1st July - Release of evaluation data and opening of submission window.
  • 31st July - Submission deadline.
  • 19th August - ISCA Clarity 2023 workshop @ Interspeech
  • 19th September - Deadline for submission of finalised Workshop papers

What is provided

  • Audio produced by a variety of (simulated) hearing aids for speech-in-noise;
  • The corresponding clean reference signals (the original speech);
  • Characteristics of the listeners (pure tone audiograms, etc);
  • The measured speech intelligibility scores from listening tests, where hearing-impaired listeners were asked to say what they heard after listening to the hearing aid processed signals.
  • Software tools including a baseline system based on HASPI scores.
