A 16-year-old from India has designed a device that converts breath into speech. High-school student Arsh Shah Dilbagi invented TALK as a portable and affordable way to aid people suffering from ALS, locked-in syndrome, and anyone else speech-impaired or paralyzed. Prototyped using a basic $25 Arduino microcontroller, Dilbagi’s invention costs only $80, or about a hundred times less than the sort of Augmentative and Alternative Communication device used by Stephen Hawking.
TALK works by translating breath into electric signals using a MEMS Microphone, an advanced form of listeningtech that uses a diaphragm etched directly onto a silicon microchip. 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 breathes into dots and dashes, converting them into words. The words are then sent to a second microprocessor that synthesizes them into voice. The morse code can either be translated into English, or specific commands and phrases. The device features nine different voices varying in age and gender.
