The voice on Lave sounds just like Braben. Really, I've listened several of his interviews and it sounds just like him.
I noticed this too, but if that's Braben, then where did he get the convincing Dutch accent? Or is he just a brilliant voice actor and is the Japanese voice in the Imperial stations also Braben? (BTW can someone turn up the volume for the Japanese lady? I'd like to get everything she's saying...)
Even though the Lave announcer sounds really Dutch, there is also something a little too British about him, at first I thought it was a native Dutchman who lived in the UK for 3/4 of his life and is trying really hard to talk with a Dutch accent.
My favourite is the Apu guy in anarchy stations who says they're running a wery reasonable regime and treacherous acts cannot go unpunished.
(And slightly modified for the forum rule 'no naming and shaming': treacherous acts must go unpublished).
