Empowering Deaf Learners Through the Language of Visuals For deaf and hard-of-hearing students, English is traditionally taught using phonetic rules that do not translate visually. Indic Sign fundamentally changes this approach. By treating English as a logical, visual map, we empower students to master vocabulary and higher-level grammar with confidence and clarity. ​Developed by the Indic AI Foundation for Social Good, Indic Sign simulates natural, first-language acquisition. We guide students from Indian Sign Language (ISL) concepts all the way to complete sentence production using a groundbreaking visual pedagogy. ​How Indic Sign Works: A 3-Step Journey 1. Conceptual ISL Foundation: We start with what the student knows. Through carefully curated images, students learn foundational concepts in their native Indian Sign Language (ISL), building a strong cognitive vocabulary without the pressure of text. 2. The Vocabulary Bridge: Once the concept is clear, we introduce the written English word right alongside the ISL sign and image. English words are no longer random letters—they become direct, visual translations of known concepts. 3. Real-Life Sentence Mastery: To teach grammar and syntax, every sentence lesson begins with a bespoke, AI-generated video showing a real-life scenario. This creates 100% congruency between the action and the sentence, ensuring the student intuitively grasps the exact meaning first. ​Visual Grammar System No more confusing grammar jargon! Once the video establishes comprehension, Indic Sign uses an intuitive visual framework to decode the written text. ​Drop Zones: Students build sentences by placing words into specific shapes (e.g., an Oval for "Who", a Hexagon for "Action", a Rectangle for "What"). ​Visual Word Linking: A unique linking - line system visually connects related words, making complex concepts like pronouns (linking "Boy" to "He") and possessive pronouns and other related words completely concrete. ​Anti-Guessing UI: Standardized token sizes ensure students rely on their grammatical knowledge, not visual shortcuts, to form sentences correctly. ​Key Features & Curriculum ​Massive Content Library: Over 1,000 interactive sentence modules providing the repetition needed for true language acquisition. ​Academic Alignment: Meticulously calibrated to cover foundational Class 2 and Class 3 CBSE English curriculum benchmarks. ​Contextual Help: Built-in visual guides and reference legends to help parents and educators support the learning process. ​Progressive Learning: Seamlessly moves students from visual comprehension to the independent production of written English. ​Who is this for? ​Deaf and hard-of-hearing students looking for an intuitive way to learn English. ​Special educators and deaf schools seeking a scalable, assistive digital curriculum. ​Parents who want to actively support their child's bilingual journey (ISL and English) at home. ​Transform frustration into fluency. Download Indic Sign today and unlock the power of visual learning!
