Just to be clear: This has nothing to do with "Wake Words" (e.g. OK Google, Alexa, Hey Siri, etc) which have always been handled offline/locally.

This is translating what you said after the wake word from voice to text on the local [Pixel] hardware rather than sending it into Google's Cloud.

The biggest benefits here are speed and reliability. It could also handle some actions offline.
