Not sure if they are still in use but they do have automatic announcements for West, Superman, Scooby, JL and Green Lantern that I am aware of (not sure about the others).
The female voice is used when the ride has stopped, but has not gone into full evacuation mode. This is also when you will see the ride operators looking around at the area, and getting ready for a ride evacuation. In the case of Scooby, the staff in the lift and high zone areas will put on the harnesses and be ready to go. The entry host at the attractions will also stop admitting guests into the queue until given the all clear.
"Ladies and Gentlemen, we are experiencing a temporary delay. Please remain seated, and the ride will resume shortly. We apologise for the delay, and thank you for your patience"
Generally if the ride can not be restarted within 5 mins, or the ride goes into an e-stop a male VoiceOver will be heard and the staff will start the unloading process. It's still seared in my brain after all these years...
"May I have your attention please, it is necessary for us to stop the ride. Please remain seated and an attendant be with you shortly to assist you from the ride. When exiting please exit via the doors marked with exit lights, follow the yellow directional lines to the marshalling area at the entrance to the ride. Once again, an attendant will be on hand shortly. Thank you"
Not sure if they are still used, but these rides certainly had this system in place.
