The 'Talk' communication device is designed to improve and augment the communicative capabilities of people suffering from disabilities that impede their ability to speak and communicate with others. The device allows users to use their breath to denote dots and dashes to form letters and words.
Breath was chosen as the medium of control because it was found to be the means available to the highest proportion of people. A special microphone is used to detect the different breath types, with International Morse Code used to translate breath inputs into word outputs.
A special algorithm allows the Talk communication device to distinguish between short and long exhales. A computing engine then synthesizes words into speech.
Controlled tests have revealed that the device has a near-perfect accuracy level. The developers of the device are aiming to raise funds for its production on crowdfunding website Indiegogo.
