👉 Oo sounds, such as the vowel sound made by "oo" in words like "boat," "moon," or "cow," are produced by allowing air to escape through an open mouth while keeping the lips rounded and the tongue slightly raised against the roof of your mouth; these sounds often have a ringing or buzzing quality, hence their name. They can be used at the beginning of words in both English and other languages and contribute to a wide variety of syllables and word structures across different languages.
