One of my favorite voice evacuation messages is this one:
I believe it’s a custom message, judging by the click when the message ends. I wish all evac messages sounded like this. It’s very concise and the speech is clear.
I don’t remember who it was but someone on this board recorded their own voice evacuation message and it sounded really good. Maybe they can work for Simplex and replace their aging default (male) voice evacuation message.
