• 3rd Clarity Prediction Challenge (CPC-3)
• Launch: March 17th; Submission: July 31st, 2025
• Workshop: 22nd August 2025, an INTERSPEECH satellite workshop

Dear colleague,

It gives us great pleasure to announce the launch of the 3rd Clarity Speech Separation and Recognition Challenge (CPC3).

The Challenge

To improve hearing enhancement technologies, such as hearing aids and hearable devices, we need reliable methods for automatically assessing the speech intelligibility of audio signals.

In recent years, we have organised the CPC1 and CPC2 Challenges to promote the development of such prediction systems. We are now launching the third round of this challenge, building on previous efforts by incorporating a more extensive and diverse set of listener data for training and evaluation.

What will be provided

• Hearing aid outputs: Audio produced by various simulated hearing aids while processing speech in noisy environments.
• Clean speech reference signals
• Listening Test Results: This includes transcripts and intelligibility scores from tests in which hearing-impaired listeners were asked to repeat what they heard.
• Listener Characteristics: Information regarding the severity of hearing impairment for each listener.
• Software Tools: Tools include a baseline system based on HASPI scores.

It gives us great pleasure to pre-announce the 3rd Clarity Speech Separation and Recognition Challenge (CPC-3) that will launch in March 2025.

The Challenge

To develop better hearing enhancement technologies, including hearing aids and hearable devices, we need reliable methods to automatically evaluate the speech intelligibility of audio signals. This requires a predictive model that takes as input both the audio produced by a hearing aid and listener characteristics (e.g., their audiogram) and estimates the speech intelligibility score that the listener would achieve in a listening test.

In recent years, we have run the CPC1 Challenge and CPC2 Challenge to advance such models. We are now launching the third round of this challenge, which builds on previous efforts by incorporating a larger and more diverse set of listener data for training and evaluation.

What will be 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.

We are delighted to announce that registration for the 5th Clarity Workshop on Machine Learning Challenges for Hearing Aids (Clarity-2024) is now open. The workshop will take place on-line on 5th December 2024 and will be focused on 3rd Clarity Enhancement Challenge (CEC3) and its outcomes.

We are pleased to announce the launch of the 3rd Clarity Enhancement Challenge (CEC3).

The challenge follows on from the success of the 2nd Clarity Enhancement Challenge (CEC2) and is about improving the performance of hearing aids for speech-in-noise. The challenge extends CEC2 is three separate directions which have been presented as three different tasks.

• Task 1: Real ambisonic room impulse responses (🔥 LIVE 🔥)
• Task 2: Real hearing aid signals (🔥 LIVE 🔥)
• Task 3: Real dynamic backgrounds (launching 1st May)

Participants are welcome to submit to one or more tasks. We are particularly interested in systems that handle all three cases with little or no redesign/retraining.

The website has been fully updated to provide you with all the information you will need to participate. The necessary data and software are available for download.

The schedule for the challenge is as follows:

• 13th April 2022: Release of training and development data; initial tools.
• 30th April 2022: Release of full toolset and baseline system.
• 1st May 2022: Registration for challenge entrants opens.
• 25th July 2022: Evaluation data released
• 1st Sept 2022: 1st round submission deadline for evaluation by objective measure
• 15th Sept 2022: 2nd round submission deadline for listening tests
• Sept-Nov 2022: Listening test evaluation period.
• 2nd Dec 2022: Results announced at a Clarity Challenge Workshop; prizes awarded.

The challenge training, dev data and initial tools will be available from 13th April. In the meantime, please visit the CEC2 Intro page to learn more about the task.
