• Say a phrase with a custom voice and speech rate:

say --voice=voice --rate=words_per_minute "I'm sorry Dave, I can't let you do that."

• List the available voices (different voices speak in different languages):

say --voice="?"

• Say something in Polish:

say --voice=Zosia "Litwo, ojczyzno moja!"

• Create an audio file of the spoken text:

say --output-file=filename.aiff "Here's to the Crazy Ones."
