Voice-Controlled Handspeak Prototype
"Voice-Controlled Artificial Handspeak System" (2014) by J. Gatti, C. Fonda, L. Tenze, E. Canessa
This open-source project establishes an automated voice to sign language translator for communication with the deaf using integrated open technologies. The prototype consists of a robotic hand -designed with OpenSCAD and manufactured with a low-cost 3D printer, which smoothly reproduces the alphabet of the sign language controlled by voice only.
The core automation consists of an Arduino UNO controller used to activate a set of servo motors that follow instructions from a Raspberry Pi mini-computer having installed the speech recognition engine Julius.
