I have installed Asterisk onto OS X (http://www.mezzo.net/asterisk/index.html) with app_swift included as well as a fully licensed Cepstral voice and am getting very choppy audio when using the Swift command. My swift.conf is below and seems to be the same as every example I have come across.
[general] buffer_size=65535 goto_exten=no voice=Allison
The output I get is very choppy, and unusable. Playing prerecorded audio files work fine.
Has anyone else came across this issue and found a way to fix it?
