it seems the old method of Swift([<Voice>^]Text to Speak) to change the
default voice doesnt work with app_swift 2.0.1 for asterisk 1.8


I have created a patch that lets you set SWIFT_VOICE as a channel variable..

exten => x,n,Set(SWIFT_VOICE=Allison)
exten => x,n,Swift(this is a test message in Allisons voice)
