Braille is a tactile writing and reading system that enables individuals with visual impairments to access information through raised dot patterns and supports independent communication and learning activities. This study presents BrailleSpeak, a smart voice-guided portable Braille interface designed to improve accessibility and daily interaction for individuals with visual impairments. The system integrates an Arduino-based control unit, Bluetooth communication, speech processing, electromagnetic solenoids, and audio feedback mechanisms to convert spoken commands into corresponding Braille characters in real time. Voice inputs received through a mobile application are transmitted wirelessly and translated into tactile outputs displayed on a compact Braille interface. Simultaneously, audio responses provide confirmation of recognized commands and generated outputs. The proposed approach emphasizes portability, affordability, user convenience, and efficient information access without continuous external assistance. Experimental evaluation using alphabetic characters and numeric inputs demonstrates reliable operation, accurate Braille representation, and responsive feedback performance. The developed device contributes to assistive technology by supporting inclusive communication, educational engagement, and independent navigation tasks. Furthermore, the design offers a practical framework for future accessibility innovations.
