Implementation of past ETV projects in Ethiopia had highlighted a unique challenge faced by sign language interpreters. Attempting to frantically sign-spell a string of technical words (for which there are no designated signs), they would fail to keep up with interpretation of the voice-over narration (even when the latter was moderately paced). The problem caused great frustration for the interpreters, and severely slowed down the production workflow. Hence, CIMC has undertaken the creation and testing of a Minimum Viable Product (MVP) system for building a Sign Language Vocabulary (SLV) specifically for academic curriculum content, to address the challenges of sign interpretation for online inclusive education.
