SOUND LESSON

How to pronounce /s/: the s sound in see

Make a clean /s/ by directing air down a groove in the tongue. Fix she-for-see confusion, s clusters such as school, and added vowels.

Vocal folds: apart

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 sides of the tongue touch the upper teeth, and the tongue tip or blade comes close to the ridge. Air runs through a narrow central groove and hits the teeth, with no voicing.

Comparing with Mandarin and Spanish

English often places /s/ in clusters: stop, street and school. Keep them together in one syllable, and listen for how the letter s may also represent /z/, as in rose.

Pinyin s is a useful reference without its vowel. Some Spanish varieties aspirate or drop syllable-final s, a legitimate regional feature, but English words such as bus need it, and school starts without an added e.

Build the sound, step by step

  1. Close your teeth almost together and raise the sides of your tongue.
  2. Blow a thin stream down the center. Hold /s/ and keep the hiss steady.
  3. Say see, sister and bus. Then begin school directly on the hiss.

What to watch for

  • A raised, retracted tongue turns see into she. Keep the tongue forward and the lips neutral.
  • Adding a vowel before or after a cluster changes the rhythm: street has one syllable.

Hear the difference in your own voice

Alternate sip and ship, then sink and think. For /ʃ/, pull the tongue back and round the lips. For /θ/, bring the tongue tip forward to the teeth. Keep the vowel fixed.
