Darren has recently merged my changes to app_swift - now supporting asterisk 12 and 13. If anyone has the Cepstral TTS engine installed and would like to link it with asterisk, app_swift is the way to go. This is the first version that 'configures' to make a Makefile. Please give it a try and report back any issues. git clone 'https://github.com/darrensessions/app_swift' cd app_swift configure make make install make reload -- Jeremy Kister http://jeremy.kister.net./
