I use the text to speech feature a lot. Sometimes, after I put the macbook to sleep and come back to it the feature no longer works. I would have to shutdown/restart the computer in order for the feature to work. Is there are a way to restart/enable text to speech without restarting the computer?

  • Try running Activity Monitor, search for the Process Name coreaudiod, and force quit it by clicking the X icon and selecting Force Quit. Speech Synthesis uses the coreaudioddaemon process for its audio output:

  • @IconDaemon that did it. The only problem now is that the keyboardshortcut is not working

  • @IconDaemon Sorry, I have a shortcut set for text-to-speach (option + esc), not that does not work.

  • Ah. This is set in the System Preferences > Accessibility > Speech sidebar. Is the checkbox checked in this setting?

have you tried entering these two commands in terminal?

killall com.apple.speech.speechsynthesisd
killall SpeechSynthesisServer

You can do that in activity monitor, I just like terminal better. Then wait a bit and try the shortcut again. If that doesn't work, try to change your shortcut to something else and then change it back. Also, maybe corrupted plist file?

  • I have to kill coreaudio every once in awhile and it takes down speech too. This fixes it. Thanks!
