Making a breath-turning machine for speech

A dedicated computer system that allows people with abnormalities, dysfunctional disorders such as ALS or Parkinson usually costs thousands of dollars. However, a 16-year-old student in India has created a device that costs only $ 80 but can complete the machine's basic mission worth $ 7,000 to $ 10,000.

The teen inventor named Arsh Shah Dilbagi calls his invention TALK according to the capacity it can perform.

TALK was developed from an Arduino circuit that costs 25 USD and several other components. The most important component is a MEMS microphone placed under the nose. This extremely sensitive microphone has a pressure-sensitive membrane engraved directly on a microchip. Thus the system has a very high sensitivity, can detect the difference between short breath and long breath, which is all the user needs to do to communicate with the outside world.

The micro controller for Arduino will translate short and long breaths into dots and dashes in Morse code, thus allowing users to spell a word with a few breaths. These codes will then be sent to a voice synthesizer to generate a series of voices based on user preferences. Dilbagi worked with a neurologist in New Delhi (India) to test the device on a Parkinson's patient, and TALK worked well as expected. This system can reliably translate dots and tiles into words.

Communication devices like Intel's help make Stephen Hawking more complex. The software keyboard that Hawking used could guess the word he wanted to say after he entered a few characters (entered by preventing the cursor from being stopped in time) before the program could complete the word. or phrase. The main advantage of TALK is that it is extremely cheap. At a price of only 1% of the price of high-end communication assistants, users are willing to accept Morse code to be able to use TALK.
