Pronunciation · consonant
The /s/ sound — s as in see
In short
/s/ is a voiceless alveolar fricative — the consonant you hear in see, listen, bus. It is voiceless: only air, no vocal-cord vibration. Below: exactly how to position your mouth, audio you can copy, the mistakes learners actually make, and drills to fix them.
How to pronounce /s/
- 1Bring your tongue close to the ridge behind your top teeth without touching.
- 2Force air through the narrow gap — a sharp hiss.
- 3Keep the tongue behind the teeth, never between them.
/s/ in words — with audio
Listen, then copy. The slow (turtle) version exaggerates the mouth movement.
- see/siː/ · sound is initial
- listen/ˈlɪsən/ · sound is medial
- bus/bʌs/ · sound is final
- study/ˈstʌdi/ · sound is initial
- possible/ˈpɒsɪbəl/ · sound is medial
The mistake almost everyone makes
Adding a vowel before s-clusters ('school' → 'eschool', common for Spanish and Farsi speakers) or lisping it towards /θ/.
Who struggles with this sound:
- Bengali speakers — s and sh interchange — 'see' and 'she' swap unpredictably
- Vietnamese speakers — final /s/ deleted — plurals and 'is/was' vanish: 'six' → 'sic', 'nice' → 'nai'
- Thai speakers — final /s/ impossible in Thai codas — plurals and final s vanish
- Japanese speakers — /s/ before /iː/ palatalises to 'sh' — 'sea' → 'she', 'sit' → 'shit(!)': high-stakes fix
