A "roar' strikes me as lower pitched; a "scream" strikes me as higher pitched, and more ragged. Without a set-up to prepare me for why this character would roar in terror it would take me out of the story -- which makes a big argument for it being the wrong word.

Now, I do know that in many self-defense classes students are taught to use a lower pitched voice when "screaming" for help -- high pitched screams can get get "caught in your throat," leaving you trying to scream but unable to make a sound (really, an even more terrifying prospect).

Or, if the author was trying to show a mix of frustration and terror -- trying to escape a velociraptor, but the hallway doors are locked shut -- that might work.


But, I'd need more of a set-up to accept the logic of the "roar in terror."
