Compa is literally retarded. Being the classic dumb blonde, Compa doesn't even know what she's saying half the time. She usually tries to use the literal pronunciation of whatever words she's saying (i.e. Happen-ed). Her voice needs to be rather high (almost to the pitch of Princess Peach's voice... or at that pitch). And due to the fact that she's a ditz, her sentences need to be slightly drawn out, because she tries to collect the miniscule amounts of thoughts she has before she actually completes her sentence.
