I just found a potential solution. The slider only goes up to a max of 350 wpm,
but the setting is stored in:
~/Library/Preferences/com.apple.speech.voice.prefs.plist
To see it, run from terminal:
defaults read com.apple.speech.voice.prefs VoiceRateDataArray
I get something like this:
(
(
1835364215,
201,
350
)
)
We need to change the last element in each sub-array.
Back up that file, in case this fails. Then from terminal, run:
plutil -convert json ~/Library/Preferences/com.apple.speech.voice.prefs.plist
-o - | python -c 'import json, sys;d=json.load(sys.stdin);[x.__setitem__(-1,
500) for x in d["VoiceRateDataArray"]];json.dump(d, sys.stdout)' | plutil
-convert binary1 -o ~/Library/Preferences/com.apple.speech.voice.prefs.plist -
If it succeeds, reboot. Only because I'm not sure how to get things to reload
without it.
Once done, your system speech rate should be set to 500. Change that number as
appropriate.
To reverse this, adjust the slider in the speech preferences.
