The "open central unrounded vowel" is a sound commonly found in many languages, including English. This vowel sound is represented in the International Phonetic Alphabet (IPA) as /ɐ/. The spelling of this sound uses the letter "a" and a symbol that looks like a small capital "a" without the horizontal bar at the top. This sound is pronounced with an open mouth, the tongue in a central position, and the lips unrounded. It can be heard in words such as "but" and "cut" in English.
