Question to the Department for Transport:

To ask the Secretary of State for Transport, what steps (a) her Department and (b) its public bodies are taking to (i) develop and (ii) use artificial intelligence approaches to British Sign Language.

Providing BSL translations of pre-recorded audio and video content on public services is a legislative Web Content Accessibility Guidelines (WCAG) 2.2 AAA criterion. As outlined in the Government Service Standard, all digital government services must as a minimum meet Level AA. AAA is best practice.

Through the Service Standard and Service Assessments, the Government Digital Service encourages departments to incorporate BSL into service design. In May this year DVSA (Driver and Vehicle Standards Agency) launched the UK Government’s first British Sign Language (BSL) online translation service for candidates booking their theory test online. DVSA held a series of user research session with BSL users, with one participant calling the service ‘life-changing’.

There are opportunities to use AI to accelerate the creation of accessible content across public services. If public bodies trial the use of AI in approaches to BSL, they would be required to conform with both WCAG and the Service Standard, and must conduct research with disabled people, including Deaf users and where appropriate to the service provision, those who use sign language or a sign language interpreter to interact with the service.

Regardless of if AI generated, services must also make sure any BSL video is culturally appropriate by working with the BSL community, testing it, or getting feedback.

The Department for Transport is committed to creating accessible communications for British Sign Language (BSL) users, as set out in our British Sign Language 5-year plan.

The Department and its public bodies have not yet directly taken steps to develop or use artificial intelligence (AI) approaches to British Sign Language. However, as described in both our Transport AI Action Plan and our Science Innovation and Technology Plan, the Department has used its First of a Kind funding programme to supported innovative AI projects like Signapse Ltd’s mobile app that uses AI to turn timetable and station information into British Sign Language for deaf customers. There are now several examples in the public domain of this kind of application of AI for providing passenger information in BSL being used by train operators and other transport providers.
