At this year's Google I/O, the company talked quite a bit about Google Assistant, and "Continued Conversation" was one of Google's main announcements… well, that feature has just started to roll out. Google has announced that the feature is not available on the Google Home, Google Home Mini, and the Google Home Max smart speakers. The "Continued Conversation" feature will basically let you have a more natural conversation with Google Assistant without having to repeat the "Hey Google" phrase every time you have a question to ask it, or you want to communicate in general.
Do keep in mind that you need to turn on this feature manually, so what you need to do is navigate to the Google Assistant app, hit 'Settings', then 'Preferences', and there you'll find the 'Continued Conversation' options and a toggle to enable this feature. Once you flip the switch, you will be able to ask Google Assistant a question, and follow up with another question, instruction, or whatever else you'd like, it's supposed to feel like you're having a conversation with your actual assistant. So, for example, you can say hi to the Google Assistant, then tell it to set a reminder, set an alarm, and follow that up with a "thank you", or if you're done, just say "stop", which will end the conversation. You will still need to activate the Google Assistant by saying "Ok Google" or "Hey Google", though, but only initially, as that is a trigger which will get it going.
As already mentioned, Google talked about this Google Assistant, and this feature in particular, quite a bit during Google I/O, and it moves Google Assistant one big step forward, that's for sure, and once again, this feature is now available on the Google Home, Google Home Mini, and the Google Home Max it seems, at least according to the company's press release which you can check out by following the source link down below, presuming you manually turn it on. It remains to be seen what is the next step for Google Assistant, especially considering that it came a long way since Google initially announced it back in May 2016.
