Use the revSetSpeechSpeed command to speed up or slow down text to speech.
The greater the wordsPerMinute, the faster the speech. (A normal speech rate for English is approximately 150 words per minute.)
The speed specified by the revSetSpeechSpeed command is used for all speeches following the command during the current session. If the computer is already speaking when you execute the command, the new speed affects the current speech.

To ensure that the command works in a > standalone application, you must include this > LiveCode custom library when you create your > standalone application. In the Inclusions pane of the > Standalone Application Settings window, make sure the "Speech" > library checkbox is checked.
