Inspired by the challenges that paralyzed people like Stephen Hawking face when communicating, Varun Chandrashekhar designed SpeakUp (https://www.varunchandrashekhar.com/research/research/speakup).

The device relies on a kind of computer analysis called machine learning, which Varun taught himself.
