So you're going to reject recordings detected as computer generated, or human recorded from a computer-generated script?

I feel like you are making your users jump through hoops to do bot and slop detection, when you ought to be investing in technology to do the same. Here is a focusing question: would you still demand audio recordings if you had that technology?

Maybe you will court an interesting set of users when you do this? I just know I will not be one of them; ain't got time for that. Good luck.
