You expose one to the end point at any given time. Then you assign an assistant to a wake word.
That voice endpoint starts with that assistant but it can absolutely Call any other assist (this is exactly how heavy tool calls like MCP Works.)
So let’s say I have Nabu. Friday and Jarvis. I’ve assigned Friday to the kitchen and Jarvis to the living room both with thier own wake word.
Now I can wake word each in thier own room and it will stay that way I can give them each a script tk facilitate ‘asking’ and have Friday ask Jarvis a question and respond. I can also run a script that tells them to swap VPEs and now Jarvis is in the kitchen and Friday is in the living room. I can open a new conversation on any vpe with any configured assistant…
Hey Fri ask Jarvis to join me in the bedroom…
Friday fires the open conversation script - for Jarvis in the bedroom. He steps up and says Hi boss, Friday said you needed me?
Options are nearly endless.
