Build/Play Messages using Scripting

[klem]

I was wondering if it would be possible to use the Actor voices to give audible messages to players instead of those large across the screen texts to replace messages such as:
GamePlay.gpHUDLogCenter(new Player[] {player},"Stukas in sector A B 2 3")

This example would use the following files in:
....\parts\bob\speech\gb\Actor1\Stukas.ogg
....\parts\bob\speech\gb\Actor1\In_square.ogg
....\parts\bob\speech\gb\Actor1\A.ogg
....\parts\bob\speech\gb\Actor1\B.ogg
....\parts\bob\speech\gb\Actor1\2.ogg
....\parts\bob\speech\gb\Actor1\3.ogg

but I have no idea what scripting would be used.

Could perhaps be used with a Passthrough Trigger etc.

Could it be used as a general module to detect a Group entering a Sector and use that to send the audio? I know the RDF is supposed to do that but I have never been sure that it does it for anything other than AI.
