The CHiME-5 dataset is available under licence.

Both commercial and non-commercial licences are available. Free non-commercial licences are intended solely for use by not-for-profit organisations (e.g., Universities, charities). All other organisations will require a commercial license regardless of intended usage. Commericial licences cost 2,000 GBP and are issued for use across the organisation and in perpetuity, for use in the challenge or any other future purpose. For those considering a commercial licence, a sample of the data is available on request. Full licence details are available at the link below.

IMPORTANT: When applying for the licence you will be asked to give contact details for a local approver. This person will be sent a message asking them to approve the application. This person must be someone other than yourself. If you name yourself as the approver the licence managing software will block the application.

Note, possession of a valid licence will be a pre-requisite for submission to the challenge.
