Czech has special sound which to me seems to be a voiced trilled r. It is written as "ř".
Wikipedia describes it a different way: A raised alveolar trill, and uses the IPA notation [r̝].
Czech speakers always seem to tell me that it's unique and that foreigners can never pronounce it. I actually can pronounce it though I have trouble with lots of other language sounds so for me it doesn't feel so exotic or difficult.
So is this a case of language pride or is Czech really the only language with this sound?
