Assist device

Hi does anyone have a suggestion? I would like to use Assist and am looking for a suitable device with which I can use it, where I can speak commands and HA responds to them.

Is there already an official Assist device or are there any suggestions for how to flash a speaker, for example?thanks

No, there is not an official Assist device yet.
