the intent for having the module and lang separate is for things where the same module can use different sets of sounds like en module and en-male or en-female lang (sound dirs) there was indeed a disconnect in the dialplan version of this app.  Originally say was only available in phrase macros so I change the syntax of the say app so you can specify both the module and the lang absolte from the dp with something like he:he as the module name.  BTW: Going forward can you attach the patch or give me instructions on how to get it in raw format or merge it to our local git, I don't really have the time to figure it out just to pull in a patch......
