Gesture Vocalizer: Making Every Gesture Heard

This paper presents a cost-effective, accessible gesture vocalizer system aimed at individuals with speech and hearing impairments. The system interprets up to 60 different hand gestures using a gyroscope and metal contact-based combinational circuits, with processing managed by an Arduino Uno. The interpreted gestures are converted into both text and speech via an LCD display and a mobile application built using MIT App Inventor. The mobile app supports multilingual output, includes an SOS feature for emergencies, and provides voice interaction through Google Assistant. The project emphasizes low-cost hardware, practical usability, and inclusive design, making it viable for deployment in low-resource settings.
