On IMDB it appears that they have the same voice actors, but to me when I saw the movie his voice sounded a bit different. Same with Starscream's.

 

It sounded less processed to me, I could actually hear Hugo Weaving's voice this time.

 

Yeah; the same thing happened with Charlie Adler's voice.

 

Seemed like they turned down the synth for everyone in the film.

 

I actually liked how Charlie Adlers voice had the processed feel, it sounded kinda like G1, and I could understand him. I don't know if it was where I sat, but I could barely hear SS :\ And Hugo was much less menacing this time, didn't have the booming feel he had in the first.

 

but they shoud have prosesed soundwaves voice more so it didnt sound like dr. claw.
