Are there any freeware voice set, so that if you are in (say) south america, that you will here a voice with an accent to match that area? I really dislike that MS just put in American accented voices. Thanks for any help.ray

No, and it can't be made with the current version of FS (no idea if it is possible with FSX). It simply is not possible to lock voices to specific regions or aircraft registrations.Besides this it is a huge task to record a decent sound set - hence no one has done it besides a single payware addon.

There are heaps of radio chatter sound sets for different locations available on the web. These can be run with freeware applications in the background whilst running FS9. See for example FSchatter and enviro! Even if you can't change the ATC itself (unless you buy Radar Contact) you are not stuck with inappropriate accents. Though I have to say I'm having trouble getting sound sets for New Zealand...Cheers,Noel.
