I just want to point out, even I set up, english language and voice in iGO regional settings, and put my .wav files in SC2057 folder as suggested, in my skin settings alert point settings speedcam voice was SC1063 and can't change that. So I created both folders, SC2057 and SC1063 and put .wav files inside. I realized later that it use files from SC1063, and I can select any language in regional settings.
Maybe someone will find that information useful.
