The open back rounded vowel is a type of vowel sound, used in some spoken languages. The symbol in the International Phonetic Alphabet that represents this sound is ɒ, and the equivalent X-SAMPA symbol is Q. The symbol ɒ is called turned script a, because it is a rotated version of script a, so-called because it lacks the extra stroke on top of a printed 'a'. Turned script a, which has its linear stroke on the left, should not be confused with script a ɑ, which has its linear stroke on the right and corresponds to an unrounded version of this vowel, the open back unrounded vowel.
