Look to Speak is an Android app from Google which enables you to
use your eyes to select a menu of phrases and pictures and have
them spoken aloud. The app uses the front-facing camera to detect
eye gaze gestures processing the feed in real time using machine
learning. When a significant gesture is detected the app will
trigger your intended action. All data is private and never leaves
the device.
