13.4 azspeech synthesize

The synthesize command will generate spoken word audio, spoken by a human sounding voice, from supplied text, and will play the audio on the system’s default audio output. With -o or --output a wav file can be specified as the output rather than having the audio played through the speakers.

$ ml synthesize azspeech [sentence]
     -f <file>     --file=<file>        Text to be spoken.
     -l <lang>     --lang=<lang>
     -o <file.wav> --output=<file.wav>  Save synthesized audio to file.
     -v <voice>    --voice=<voice>
