This document is the product of consultation between the University of Surrey, Signapse AI Ltd and representatives of from the Deaf community. It attempts to describe a taxonomy which can be used to compare and contrast the functionality of computational approaches that attempt to achieve automatic translation of spoken language into sign language. We have endeavoured to make this framework language unspecific so it can be used to compare contrasting approaches, that employ different technological solutions across different languages. It provides a roadmap to quantify the steps towards fully automatic translation.
