Assistive Speech Device for People with ALS

My project is aimed at people who have been affected with ALS and have lost the ability to speak and give them that power back.

The device is powered by a Raspberry Pi 3 and uses a Sip & Puff for input. The code that powers the software is written in python 2.7.9 and uses Twilio, Pygame, and espeak libraries. A person interacts with the software by sipping and puffing morse code to spell out words and phrases. the device has text to speech and texting capabilities to communicate with people. There is a library with around 10,000 of the most common words in the English language that they can access to input a short sequence of morse code instead of spelling out the entire word. This helps increase the speed at which he or she can speak and increase ease of use.

Code for the project.

We are doing something similar with Android devices: maybe we should team up?  It would be nice to have a low cost puff/suck input device for an Android.
