Lift your bottom lip so its inner edge (where the wet part meets the dry part) touches the very bottom of your top front teeth. Add vocal cord vibration as you blow air through.

Americans pronounce volcano as vahl-KAY-noh (/vɑlˈkeɪnoʊ/). The L in "volcano" is a dark L — the back of the tongue rises toward the soft palate, adding a small "uh" quality before the L. This is called the Dark L vs Light L, and it's why Americans sound more relaxed than the textbook. It comes out as vahl·KAY·noh. Stress falls on the second syllable — keep everything else short and quick. You'll hear it in sentences like "A volcano formed the landscape millions of years ago" or "The volcano erupted, spewing ash and lava into the air" — more examples below.

Relax your lips and drop your jaw significantly. The tongue tip lightly touches behind the bottom front teeth and the back part of the tongue presses down a little to create more dark space in the back of the mouth.

Keep the tongue tip down and pull the back of the tongue up toward the throat. The 'dark' sound comes from the back.
