Abstract: Abstract An adaptive AI-based real-time bidirectional sign communication system coordinates seamless accessibility translation between signing and non-signing users across web and mobile platforms. The system incorporates a sign recognition engine for converting camera-captured gestures into text, alongside a speech recognition module and a sign avatar generation module that translates voice or text into an animated three-dimensional signing avatar. A contextual interpretation engine provides sentence-level semantic adjustments, while an AI personalization engine continually adapts recognition parameters to individual user speeds and styles. To overcome network instability, the platform features an adaptive compression engine that prioritizes visual clarity for hands and faces, and a low-bandwidth skeletal transmission engine that replaces heavy video streams with lightweight mathematical joint coordinates under constrained network environments. The integrated system further includes an emotion detection module, an offline AI processing module, and an automated emergency communication module.
