revSpeak not working on Mac

[Bill Vlahos]

In LiveCode 10.0.1 (rc 3) and 9.6.13 on a Mac with an Apple processor (MacBook Air M2), when I put the following script  in a button, nothing happens when I press the button in either the IDE or standalone.

on mouseUp

revSpeak "Hello World"

end mouseUp



I am loading revLoadSpeech in the Standalone.



Does this work on a Mac with Apple processors? If so, what could I be missing?



Thanks
