Abstract
Assistive communication technologies play a critical role in enabling independent interaction for individuals with multiple disabilities. This paper presents the design and implementation of an ESP32-based Braille-to-speech communication system for visually and vocally challenged users. The system employs a 4×4 keypad matrix to capture Braille patterns and utilizes UART-based serial communication to transmit processed text to a computer for speech synthesis. The generated text is transmitted to a computer via serial communication, where a Python-based text-to-speech engine synthesizes the corresponding speech output. Experimental evaluation demonstrates that the system provides accurate and reliable communication with minimal response delay.
