Sign BSL is a British Sign Language dictionary for looking up and comparing words and phrases. Its site lists just over 21,000 sign videos contributed by more than 150 signers, with access on the web, Android and iOS. Users can search for vocabulary, compare sign variations and practice through the mobile app. Featured videos have normal and slow playback controls, and offline access is listed. The dictionary is described as serving learners, teachers and the Deaf community. It includes GCSE Vocabulary and Signature Level 1 and Level 2 sections. A word may have more than one sign because of differences in meaning or regional usage. Word definition information comes from WordNet by Princeton University. Listed video sources include ICT Signs, Scottish Sensory Centre, BSL Parlour, SignMedia Enterprise, Deafax and The Deaf Academy. Users can contact the maker to suggest videos or report errors, though the contact page requires JavaScript. The Sign BSL Dictionary plan provides free unlimited access.
