Automatic Transport Announcements in Sign Language: How does it work?

Updated: May 24, 2023



Signapse has quickly become a game-changer in the world of sign language interpretation since its launch a year ago. Developed with and for the d/Deaf community, Signapse software is designed to provide a cost-effective solution to communication barriers for d/Deaf individuals, empowering them with equal access to information and services.


We have already deployed our automatic transport announcement software, which uses AI-powered videos to provide live updates on train, airport, airline, ferry and bus information including welcome messaging, times, platform/gate numbers, destinations and disruptions, all in sign language.


In this article, we will explain how our software works, as well as how it can be accessed by the d/Deaf community. We also answer some of the most frequently asked questions we receive.


How does this product work?


Here we break down our process, from selecting the right video recordings to displaying the final announcement on transport hub screens:

  • We start with our database of all possible announcements and their corresponding pre-recorded sign language translation videos.

  • A set combination of sign language videos is chosen by our translators, based on the required content of an announcement.

  • Using AI, these videos are blended together for a seamless sign language translation of the announcement with the correct syntax and grammar.

  • Our use of AI and integration with transport data feeds means that changes to destinations, departure times, and platform numbers can be made automatically. Announcements in sign language are generated in real-time.

  • Our software integrates with digital displays and sign language videos are shown on screens around the train/bus station or airport.

  • This provides equal access to information and services for the d/Deaf community.

How can it be accessed and used by the d/Deaf community?

Sign language transport announcements are currently available at hubs across the UK. Deaf passengers can access the announcements at selected digital screens. However, we understand that accessibility is key, and we are working on improving its messaging and advertising of the location of these screens. We are actively communicating with local d/Deaf communities to ensure that the information is widely available.


If you would like to see more of these announcements at bus and train stations or airports near you, we encourage you to get in touch with them. By expressing your interest and support, you can help increase awareness and access to our sign language announcements.


Frequently Asked Questions


What are your plans for transport announcements in the future?


In terms of future plans, we are expanding the current scope of announcements to include emergency and disruption information as it happens. We are also working on expanding our sign language announcements to more airlines and airports.


Our goal is to provide equal access to information and services for the Deaf community across all modes of transportation.


How do you plan to continue improving the software?


We are committed to continuous improvement and refinement of the software, and welcome feedback and input from our users to help us achieve this goal.


What are some potential challenges of putting transport announcements in place and how are they being addressed?


One limitation of our transport announcement product is the need for a digital screen to show the videos on. We use displays that can be moved around and are putting our software on screens that are always in one place. This means that wherever you move around on the station you can see the information.
