Here is a field recording from some of the early research into ǃXóõ, a click language which has the most distinct sounds (consonants and vowels) of any known language. The recording in the language itself starts at 2:45 - it's incredible and kind of funny to listen to. (If you want to know how "ǃXóõ" itself is pronounced, listen to the first 20 seconds or so.)
