Feel it

Put a hand flat on your throat and say the sound. You should feel nothing at all until the vowel begins — any buzz means you have switched the voice on too early and made the voiced partner instead.

Hear the difference

Minimal pairs to drill

Each of these is two words separated by exactly one sound. If a listener hears the wrong one, the problem is the contrast, not the effort.

Transfer

If your first language is…

Nothing here is about ability. Every one of these is a sound system doing exactly what it was built to do, applied to a language that asks for something else.

  • HindiUrdu

    Hindi and Urdu have S, so it is secure, but a word-initial s-plus-consonant cluster often gains a vowel in front, so 'school' becomes 'ischool'.

  • Punjabi

    Punjabi commonly adds a vowel before an initial sp-, st- or sk- cluster, so 'station' becomes 'istation'.

  • Bengali

    Bengali's main sibilant is a sh-type sound, so English S often comes out as 'sh' and 'sun' becomes 'shun'.

  • Mandarin

    Mandarin has s but no final consonants, so 'bus' and 'class' tend to lose the hiss at the end.

  • Cantonese

    Cantonese s is fine at the start, but Cantonese syllables cannot end in s, so final S needs holding.

  • Japanese

    Japanese s becomes 'sh' before i, so 'seat' and 'sit' can start with a hush.

  • Korean

    Korean s also palatalises before i, giving 'see' a sh-like start, and word-final s is not released.

  • Vietnamese

    Vietnamese has no final s, so plural and third-person endings are easily dropped.

  • Thai

    Thai allows s only at the start of a syllable, so a final S is commonly replaced by an unreleased t.

  • Spanish

    Spanish has no word-initial s-plus-consonant cluster, so 'Spain' gains an e in front; the S itself is fine.

  • German

    German pronounces an initial s before a vowel as /z/, so 'sun' can begin like 'zun', and initial sp-, st- become 'shp-', 'sht-'.

  • Arabic

    Arabic has both a plain and an emphatic s, and the emphatic one can colour the vowel after it, making 'seat' sound darker.

Questions

Straight answers

Is /s/ voiced or voiceless?

It is voiceless. Put a hand on your throat: you should feel nothing until the vowel after it starts. That is the only difference between it and its partner sound, which is made in exactly the same place.

What words start with the S sound?

Common ones include sun, see, city. In the middle of a word you get listen, person, outside, and at the end bus, nice, class. Every one of those links to its own pronunciation page here.

How is /s/ spelled in English?

It is written "s", "ss", "c", "ce", "se", "sc", "ps". English spelling and English sound came apart centuries ago, so the same sound turns up under several spellings and the same spelling carries several sounds — which is why the sound, not the letter, is the thing to learn.

Why do Hindi & Urdu speakers find /s/ hard?

Hindi and Urdu have S, so it is secure, but a word-initial s-plus-consonant cluster often gains a vowel in front, so 'school' becomes 'ischool'.
