TALK-An AAC Device: Converting Breath into Speech for the Disabled

Built by: Arsh Shah Dilbagi, 17, of DAV Public School, Panipat, Haryana

Category: Third Award in Embedded Systems category

TALK is a portable and affordable device designed for disabled people with locked-in syndrome. It works by translating breath into electric signals using a MEMS Microphone. The user is expected to be able to give two distinguishable exhales varying in intensity or time, so that they can spell words out using Morse code.

A microprocessor then interprets the breaths into dots and dashes, converting them into words. The words are then sent to a second microprocessor that synthesizes them into voice. Morse code can either be translated into English, or specific commands and phrases. The device features nine different voices varying in age and gender.
