Oh i would even vote against the timer ...
I believe since this game is created with the idea "the world will wait for you, player" ... it should be kept in mind all the time. :-/
That point about own agenda is true ... but that is core of the problem, those who have their own agenda would never satisfy with someone else doing something fitting his own only.

I mean, we can imagine that rolling as who speaks first ... but it feels odd, that everyone else let you do litteraly anything, bcs it would be rude to interupt you.

Therefore i can imagine two options ...
Either voting for the final answer (in fact, just the same as they allready included for Twitch) ... and then rolling for who will say it (and if that option would include diceroll ... proficiency and stat bonus should be added to the roll, simmilar to initiative ... so there is higher chance, that most proficient will be the one who would talk).
Or, wich would be quite problematic, but also awesome, especialy in some cases ... everyone speaking their mind, and then kinda brainstorming about it, before thei confrim that option to the NPC.

Ofcourse i see the main problem with this, when they would try to deceive, or intimidate ... it would look incredibly suspicious, to then start argue if that is actualy the thing they want to say.
