I am trying to increase the speed of the Text-To-Speech on my Mac. The GUI Preference pane maxes out at 360 words per minute. I do accessibility development and this is actually a little slow for me.
I have found the preference file for voice settings: com.apple.speech.voice.prefs.plist
and I know the key: VoiceRateDataArray
However, when I read the preference I get an array of arrays.
So how do I write the command line command to over-write the specific element of the array to speed up the voice in OS X.
I cannot seem to find an example to deal with arrays and the defaults command.
