How can I use the automator to create text-to-speech service that talks faster than the current service?
Do this:


Remove the "Speak text" action.
Add the "Run AppleScript" action.
Clear all the default text in the action.
Copy/paste this script in the action:



on run {input, parameters}
  repeat with thisText in input
      say thisText speaking rate 400
  end repeat
end run



If you want a specific voice, append using "SomeVoiceName" after the say command.

Example : say thisText speaking rate 400 using "Bruce" -- Bruce is a name of the voice
