SignON - Sign Language Translation Mobile Application and Open Communications Framework

Project description

Bridging the communication gap between the deaf and the hearing

People who are deaf or hard of hearing face the challenge of interacting with others in real-life situations and are often excluded from accessing information in society. The EU-funded SignON project aims to develop a mobile application that will translate between different European sign and verbal languages. The application, a lightweight software running on a standard mobile device, will interact with a cloud-based distributed framework dedicated to the computationally heavy tasks. The application and the framework will be designed through a co-creation approach where users will work together with the SignON researchers and engineers. The application will be easily adaptable to other languages (sign and spoken) and modalities and will ultimately promote equitable exchange of information among all European citizens.


Nowadays any communication barrier is detrimental to society. This project will research and develop the SignON communication service that uses machine translation to translate between Sign and spoken languages. This service will facilitate the exchange of information among deaf and hard of hearing, and hearing individuals. In this user-centric and community-driven project we will tightly collaborate with European deaf and hard of hearing communities to (re)define use-cases, co-design and co-develop the SignON service and application, assess the quality and validate their acceptance. Our ultimate objective is the fair, unbiased and inclusive spread of information and digital content in European society.
Our project will develop a free, open application and framework for conversion between video (capturing and understanding Sign language), audio and text and translation between Sign and spoken languages. To facilitate these tasks we propose a common representation for mapping of video, audio and text into a unified space, that will be used for translating into the target modality and language. To ensure wide uptake, improved sign language detection and synthesis, as well as multilingual speech processing on mobile devices for everyone, we will deploy the SignON service as a smart phone application running on standard modern devices. We envisage the application as a light-weight interface. The SignON framework, however, will be distributed on the cloud where the computationally intensive tasks will be executed.The project will be driven by a focused set of use-cases tailored towards the deaf communities. We target the Irish, British, Dutch, Flemish and Spanish Sign and English, Irish, Dutch, Spanish spoken languages. However, SignON will incorporate sophisticated machine learning capabilities that will allow (i) learning new Sign, written and spoken languages; (ii) style-, domain- and user-adaptation and (iii) automatic error correction, based on user feedback
