For those not in the know, Continued Conversation mode allows you to make an initial request, then keep hitting your AI assistant with follow-up questions without repeatedly having to say “OK, Google” for a set period of time. This not only allows for a more conversational and less robotic interactions with a device like the Google Home Hub, but it’s also less annoying and repetitive.
Google says that you can enabled this feature by going to Settings --> Preferences --> Continued Conversation in the Google Assistant app for Android or iOS. In addition to the aforementioned Google Home Hub and Lenovo Smart Display, LG XBOOM AI ThinQ WK9 (say that three times fast) and the JBL Link View.
For those that show a preference for Amazon’s Alexa-powered Echo family of devices, they support a similar feature called Follow-up Mode.
Earlier this month, Google came under fire for its decision to include a microphone in the Nest Secure, and subsequently “forgetting” to inform users of its presence. Google only acknowledged the existence of the microphone when it added Google Assistant functionality to the Nest Secure, after which a company spokesperson stated, "The on-device microphone was never intended to be a secret and should have been listed in the tech specs. That was an error on our part.”
