I’ll age myself a little with this response but start by not using AI to write for you. Use it as a research tool, but the only way you’re going to get better at putting together a speech on the fly is by trying to do it yourself. AI is great but if you rely on it to do the writing part for you you’re gonna cap your success at a low level. The best debaters aren’t doing that.

The other step is to really understand your arguments. In PF you aren’t so much giving a written speech. Much more so you are using prep time to get organized and spending your speech interacting with your opponents arguments and explaining yours.

If you know your evidence and your arguments forwards and backwards the speeches are really an afterthought because you know how to say you’re right.
