No, mine is just the “I’m a-” from “I’m all the Jedi” mushed straight into the “-uh Jedi” from the end of the same phrase, with a bit of trial-and-errored overlap and fading. I didn’t add any sounds from elsewhere, just a touch of reverb to smooth over that transition a bit more.

It’s definitely “I’m a Jedi” not “I am a Jedi”, but I think if you really want the latter you’d need to find a way to stitch together a more defiant delivery of the whole line from syllables elsewhere, which is beyond my level of effort. I don’t think there’s anything wrong with Sherlock’s version; I just opted to try to copy it myself while I was doing the Palpatine line swap, rather than bother cutting it out of his streamable link.
