Abstract

A “Hand Gesture recognition for voice-free Communication using ESP32” introduces an intelligent communication aid that converts physical gesture into audible speech, enhancing interaction for speech disturbed individuals. Key components are flex sensors, DF- mini player, speaker, Esp32 microcontroller and a SD card, they work together to detect, process and translate gestures into voice. The flex sensors track finger movements. The microcontroller processes these signals, mapping them to pre- defined speech outputs. It provides an inclusive, user-friendly solution to support non-verbal communication in everyday situations.
