Hello I really wanted to customize my iPhone so I was wondering if any one knew of a sound-making software that would say words in a British Accent. For example either with a mic or like Mircrosoft San Serfif (You type in the words and he says them)

I wanted a custom lock and unlock sound that would say "System Locked" and 'System Unlocked" in a British Accent.

Yes I've already downloaded the customize British Female sound set but it doesn't have a British Accent to it.

So please help me if you know of such a software.
