Total tangent: one thing I find frustrating about the bard fluff is that it conflicts with the mechanics. I love the idea of roleplaying Cutting Words by flinging actual silly insults ("You fight like a dairy farmer!")--but how can you roleplay doing that in the middle of someone else's sword swing when you see they're about to hit in the midst of chaotic melee, while you're busy Inspiring another comrade and casting a spell? Just how fast is this bard talking? It ends up disrupting my sense of immersion and, as a DM, I wind up wanting to reflavor the bard as just using magic for these tasks, even if it's not the newfangled wizardly-type spell magic. (Cutting words = you hum a chord of dissonant notes which resonates strangely in the enemy's mind. Also explains why language doesn't matter.)
In our group we don't get too "crunchy" so it works fine. If it takes me longer than 6 seconds to complete what I'm saying, then maybe that round was a bit more than 6 seconds, or my character's action spills a bit into a round where he wasn't using one of these abilities. Of course, my insults are a bit more involved, "What's the difference between your mother and a Mind Flayer? If I ever sleep with a Mind Flayer I'll let you know!"
However, if worrying about the correct length of time of each round is of concern to you, maybe cutting words is just that, "You're dead!!!" "Try again loser!" "Eat dirt!"
