Continued Conversation coming to all Smart Displays in the US

Continued Conversation is coming to all Smart Displays powered by the Google Assistant in the US that are set to English. On devices with screens, this active listening state is noted by an Assistant icon in the top-left corner of the screen. The logo appears as a response is being issued, but switches to the four color dots/voice waves as users speak to denote activity. This is an optional feature that users can opt in and out of.
