Lol, I’m pretty sure they say in the Visual Dictionary he speaks Sith. It sounds like Sith. Even more reason to replace it with Palpatine’s broadcast, even if it wasn’t the whole thing.

I wish there was a way to imply Poe was sending his speech as a message with Chewie and Han to broadcast to the Core Worlds. So that way, Poe plays a crucial leadership role by countering Palpatine’s message of fear with a message of hope. So it is Poe that pushes the galaxy to stand together, rather than Lando just being Lando. Maybe we could R2 recording Poe during his speech, then see R2 plugged up to the Falcon during the montage? Not really sure.
