I'll be honest: "I. AM. TALKING!" isn't a real Magic: The Gathering keyword or ability. It doesn't appear on any official card, in the comprehensive rules, or in any sanctioned set. It sounds like a meme, a joke card, or something from a custom/homebrew set rather than genuine MTG vocabulary.
If you encountered this on a card, it's almost certainly an unofficial, silver-bordered parody, or fan-made content that isn't tournament-legal and won't have defined rules interactions in Commander.
If you meant a real mechanic, I'd be happy to help—did you perhaps mean something like "Goad," "Monarch," "Council's dilemma," or another political or table-talk-related ability? Let me know the actual term or share the card text, and I'll give you an accurate breakdown of how it works and when it matters in EDH.
