I do these as DM for as many characters as possible and it really helps to make the characters stand out much faster. The noble ranger sounds like Sean Connery, the town guard sounds like the dopey cop from Hot Fuzz (the one who doesn't know how to do his job), and the manipulative devourer calling the shots from behind the scenes sounds an awful lot like Mr. Smith from The Matrix. It cuts out many descriptors and immediately allows the characters to develop an impression without dice rolls and introductory chit-chat. And you can use it to your advantage - the devourer is actually on their side but they never trusted him.
The key, I find, is having a catch phrase to fall back on. If you start to slip, use your catch phrase (even if it's just to yourself for practice). And if it slips up, so be it. Unless you're a professional voice actor, I'm sure they can let it slide. If not, treat them like they're a professional adventurer and kill their character.
