KURAL ACC ASSISTIVE VOICE AND SIGN

Augmentative and Alternative Communication (AAC) technologies support people who experience difficulty communicating through speech. This paper presents Kural AAC, an assistive communication platform designed to bring picture-based communication, sentence construction, speech assistance and sign-language support together in a unified interface. The prototype dashboard provides access to an AAC communication board, a sign-language assistant, a voice assistant, communication history and application settings. The AAC board organizes familiar symbols into categories such as needs, food and drink, feelings, people, activities, emergency messages and quick phrases. Users can select symbol cards to construct a message, view the sentence and request spoken output. English and Tamil are presented as language choices in the interface. Additional screens illustrate account registration, role selection, speech preferences and communication logs. The sign-language assistant screen provides a camera-based interaction area and a panel for recognized signs, while the voice assistant screen presents microphone dictation and typed-phrase speech controls. The paper describes the prototype screens, functional scope, logical architecture, data organization, interaction algorithms, accessibility considerations and a verification plan. The supplied screenshots provide evidence of the interface design; they do not by themselves establish the accuracy of sign recognition, speech recognition, backend persistence or completed user testing. Kural AAC is therefore presented as a project prototype and design contribution, not as a clinically validated communication intervention.
