The TTS pronounciation is terrible to me at normal speed, sounds like half the words are missing :(
Hi, I'm sorry to see you're having trouble with the TTS, it must be so frustrating. All I can recommend is to try another browser :/
You could visit Ivona here and try out the voices. Duo's voice for Polish is Maja, see if it sounds okay there. But i don't see any help or troubleshooting on the Ivona website, it might not be much help to you.
Actually, I have the same question. Why is "We're talking about the man" wrong?
I thought "mężczyźnie" is plural and not singular!? Because of the line above the second Z.
