I've answered this question multiple times in this thread, in replies multiple posters. I haven't gone back to check if I've answered it in a reply to you, but I expect that I have.
@zakael19 has also answered, in replies to you.
Here is the relevant rule, from p 103 of the Revised rulebook:
When scripting these maneuvers, players must speak their parts. Spitting out moves in a robotic fashion is not a viable use of these mechanics. The arguments must be made. Of course, no one expects us all to be eloquent, so just the main thrust or a simple retort usually suffices (but a little embellishment is nice).Keep it simple and to the point. Say what you need to in order to roll the dice. A multipoint statement should be broken down into multiple actions across the exchange.
What is said correlates to what sort of action is rolled. And also - as I've posted upthread - determines the content of any compromise.
I don't understand why this is being treated as some sort of mystery!
They have to speak. Does the GM decide if they are "speaking robotically" or if it's not adequately addressing the situation?
But yes, it is clear that the content of their statement has no impact on chance of success. Which to me means the player has less agency for this type of interaction than in my D&D campaign.
