Vocal folds: vibrating

TongueTeethUvula

Simplified human pronunciation. The small uvula hangs from the palate; it is not the vocal folds. The wave indicates voicing.

Voice settings

The mouth starts slightly open. Movement is slowed for observation; the synthetic sound plays once at its original speed. Pause holds the current mouth shape; reset returns to the relaxed position. The panda is a symbolic teaching aid for human pronunciation, not animal anatomy.

What your mouth is doing

The lips round firmly, and the tongue rises high, usually with the back raised. In many modern accents, the tongue sits more central than older descriptions suggest. American references write /u/, and British ones /uː/.

Comparing with Mandarin and Spanish

Many spellings share this vowel: oo, u, ue, ew, o in two and ough in through. Some words, such as music, also have a /j/ glide before it, written /ju/.

Mandarin wu and Spanish u are close starting points. The main challenge for both groups is keeping this vowel separate from the relaxed /ʊ/ in book.

Build the sound, step by step

Round your lips into a small circle and raise your tongue.
Hold blue steadily with firm lips, without opening at the end.
Say food, moon and through, and notice the spelling variety.

What to watch for

Relaxing the lips turns fool into full. Keep them firm.
Reading through and two by spelling gives wrong sounds; learn them whole.

Hear the difference in your own voice

Compare pool and pull, then food and foot. Use firm lips and a longer vowel for pool and food. Relax your lips for pull and the vowel in foot.
