Cepstral Community

What is the easiest method to call the Cepstral TTS engine from the python script? (any sample code)
is it possible to access the features of Cepstral TTS engine natively using python? (Any API documentations)

Try the subprocess module:

import subprocess
subprocess.call(['swift', "text to be spoken"])

to read a file:

subprocess.call(['swift', '-f', 'filename.wav'])
