Even if you=E2=80=99ve not worked on = hearing aids before, we=E2=80=99ll provide you with the tools to enable you to appl= y your machine learning and speech processing algorithms to help those with a hearing loss. Although age-related hearing loss affects 40% of 55 to 74 year-olds, the majority of adults who would benefit from hearing aids don=E2=80=99t use th= em. A key reason is simply that hearing aids don=E2=80=99t provide enough benefit= . In particular, speech in noise is still a critical problem, even for the most sophisticated devices. The purpose of the =E2=80=9CClarity=E2=80=9D challen= ges is to catalyse new work to radically improve the speech intelligibility provided by hearing aids. The series of challenges will consider increasingly complex listening scenarios. The first round, launching in January 2021, will focus on speech in indoor environments in the presence of a single interferer. It will begin with a challenge involving improving hearing aid processing. Future challenges on how to model speech-in-noise perception will be launched at a later date. *The task* You will be provided with simulated scenes, each including a target speaker and interfering noise. For each scene, there will be signals that simulate those captured by a behind-the-ear hearing aid with 3-channels at each ear and those captured at the eardrum without a hearing aid present. The target speech will be a short sentence and the interfering noise will be either speech or domestic appliance noise. The task will be to deliver a hearing aid signal processing algorithm that can improve the intelligibility of the target speaker for a specified hearing-impaired listener. Initially, entries will be evaluated using an objective speech intelligibility measure. Subsequently, up to twenty of the most promising systems will be evaluated by a panel of listeners. We will provide a baseline system so that teams can choose to focus on individual components or to develop their own complete pipelines. *What will be provided* - Evaluation of the best entries by a panel of hearing-impaired listeners. - Speech + interferer scenes for training and evaluation. - An entirely new database of 10,000 spoken sentences - Listener characterisations including audiograms and speech-in-noise testing. - Software including tools for generating training data, a baseline hearing aid algorithm, a baseline model of hearing impairment, and a binaural objective intelligibility measure. *Important Dates* - January 2021 - Challenge launch and release of software and data - April 2021 - Evaluation data released - May 2021 - Submission deadline - June-August 2021 - Listening test evaluation period - September 2021 - Results announced at a Clarity Challenge Workshop in conjunction with Interspeech 2021 Challenge and workshop participants will be invited to contribute to a journal Special Issue on the topic of Machine Learning for Hearing Aid Processing that will be announced next year. *For further information*If you are interested in participating and wish to receive further information, please sign up to the Clarity Forum at http://claritychallenge.org/sign-up-to-the-challenges If you have questions, contact us directly at contact@xxxxxxxx *Organisers*Prof. Jon P.
