I found this website: http://www.speechtech.cz/demo.php It's generator of Czech voice - and pretty good by my opinion /rhytm is sometimes little odd, but pronunciation is good/. You write Czech text in textbox, press [Syntetizovat] button and then you can hear generated voice. Good tool to find out right pronunciation.
Eso, that's great. Now that is a good learning tool. I saved that one to favorites. Wonders never cease what you can find on the internet.
