I have the R1 and I get a kick out of the voice every time. "Battery fulled" is my favorite. When I start recording it says "video recording" and when I stop recording it says "video recording stopped." If I am moving, it's too quiet to understand, but it stops my music while it speaks. I often forget to start recording at the start of my ride, so I press the button to check. I can only tell by how long the pause is while the voice speaks. That's the only prompt I have a problem with, as it's the only one I get when I'm on the move. The others are only when I turn it on. "Welcome to FreeConn product. Battery XX%. Connected." It's certainly not the highest quality product, but it meets my needs comfortably and paying more feels like a waste of money to me. I hope you get a lot out of value out of it.
