Sign language functions as a fundamental communication system for deaf individuals while population-wide ignorance about sign language presents a major obstacle. Sign language translation systems available today deal with performance problems that include long delays between communication, restricted language availability, and poor recognition of natural hand movements. The proposed real-time IoT-based sign language translator equips a smart wearable flex and IMU sensor-embedded glove for sign language translation purposes. A modified LSTM model operates within the system for gesture recognition and delivers 97.2% precision through a 180ms translation response period. The cloud system supports extended language options through its 10+ multilingual speech features. The user experience evaluation met a rating of 4.8 out of 5 while the device operated for 12 hours on a single charge. The proposed system enhances both latency speed by 30% and classification precision compared to earlier models. This invention delivers a customizable system that enables instant accessible communication.
