It's difficult to make absolutely no mistakes, even for people with ample experience. To prove that, we set out to record real mistakes made by professional VO (voiceover) actors. We gathered 10 professional VO actors and had them read fake scripts over and over again. They were not informed of our real purpose, and we succeeded in recording some great mistakes they made. Please note that we did not dub the mistaken lines in the uploaded MP3 files, because we want you to enjoy the mistakes as they happened, and the actors' real reactions.
