"Mouchy ho mají rády" is accepted. There is no current report in the system for it, so we can't tell you why it was rejected. But if that was exactly what you wrote, you likely have run into the intermittent grading bug.
In the sentence TTS it sounds acceptable to me. The sound for the individual word tile is incorrect. I disabled it but it is quite likely that it does not make anything. There is nothing more that can be done.
