/s/ /z/ /ʃ/ /ʒ/

The S, Z, SH and ZH sounds

The sibilants are the hissing family. /s/ and /z/ are a narrow, focused hiss; /ʃ/ (sh) and /ʒ/ (measure) are broader and further back with rounded lips. They are also where most lisps live.

Who this is for: Anyone with a lisp, speakers who merge /s/ and /ʃ/, and learners tackling English plural and -s endings.

Where to put your tongue

  1. 1For /s/, put the tongue tip just behind the top teeth without touching them, and aim a thin stream of air down the centre groove of the tongue.
  2. 2Keep the teeth close together. If the tongue pokes through, you get a lisp (a 'th' sound).
  3. 3/z/ is exactly the same shape with the voice switched on.
  4. 4For /ʃ/ (sh), pull the tongue slightly back, flatten the groove, and round the lips.
  5. 5/ʒ/ (measure, vision) is /ʃ/ with the voice on — it never starts an English word.

Common mistakes

  • Frontal lisp: the tongue pushes between the teeth so 'sun' becomes 'thun'.
  • Lateral lisp: air escapes sideways, producing a wet, slushy /s/.
  • Merging /s/ and /ʃ/, so 'see' and 'she' sound identical.
  • Missing the /ʒ/ in words like measure, usual and decision by saying a hard 'z' or 'sh'.
