Google's ‘Look to Speak’ Android app uses a phone’s front camera for eye gaze tracking, TTS

“Look to Speak” is a new experimental app from Google that helps those with speech and motor impairments communicate through eye gaze technology.

The app lets people look left and right — relative to a phone placed directly in front of them — to select from a list of phrases, which can be customized. There are two columns of text, with selections then spoken aloud. 

Look to Speak leverages eye gaze technology that uses the front-facing camera found on Android devices. A clear view of the user’s eyes is required, while the phone has to be securely mounted and not just held in hand. The application features a Setup Helper, while there’s a Practice Screen to get started.

Customization options let users set the gaze off-screen distance (close, medium, and far), as well as the gaze duration needed to trigger. A feedback ping is available to confirm every selection. The app can be paused/”snoozed” at any time (by looking up) so that it’s not always looking for your gaze.

This assistive tool is part of the Experiments with Google platform’s “Start with One” project:

Look to Speak is available today on Android 9+ phones, as well as Android One, and Google has published resources to help use the tool.
