The video is choppy and his mouth doesn’t seem to match the language at times.
The audio is better quality. However they spliced it or forged it, they did a decent job. It sounds like his voice and not a voice actor, but it doesn’t sound choppy or unnatural.
That sounds nothing like him!

He didn’t call the aliens “president”
Biden is extremely hard to deep fake because he’s so batshit stupid.
