In short

French u in tu is /y/: keep your tongue high and forward while rounding your lips. French ou in tout is /u/: keep your lips rounded and move your tongue further back. The lips are rounded for both; the tongue position changes.

Three pairs with the same consonant

The vowel changes the word
u: /y/Meaningou: /u/Meaning
tu /ty/you, singular informaltout /tu/everything
rue /ʁy/streetroue /ʁu/wheel
vu /vy/seenvous /vu/you, plural or formal

The IPA symbol /u/ represents French ou, as in vous. The symbol /y/ represents the vowel in tu. Read each symbol with its model word. In these pairs, the consonant stays the same, so you can focus on the vowel.

How do you pronounce u and ou in French?

A mouth-position experiment

  • Start with /i/, the vowel in French si. Keep your tongue high and towards the front.
  • Round your lips while keeping the tongue forward. Aim for /y/, as in tu.
  • Keep your lips rounded and draw the tongue further back for /u/, as in tout.
  • Alternate tu — tout — tu — tout. Keep each vowel steady, with no extra “y” or “w” sound.

Use a mirror for the lip movement. For the tongue movement, compare the feeling of /i/ with your attempt at /y/: the tongue stays towards the front even though the lips change. Then compare your words with a clear spoken model or ask a French speaker to tell you which word they hear.

Put both vowels into one sentence

Tu prends tout ?

Are you taking everything?

Tu has /y/; tout has /u/. The final written t in tout is silent here.

La roue est dans la rue.

The wheel is in the street.

Say roue /ʁu/, then rue /ʁy/. Keep the initial consonant the same.

Vous avez vu Nora ?

Have you seen Nora?

Vous has /u/; vu has /y/. Move the tongue forward for vu.
