Z Sound: Speech Therapy Guide, Words & Games
The /Z/ sound is written /z/ in the phonetic alphabet, and most children master it by age 4-5. This guide covers how to make the /Z/ sound, 59 practice words split across initial, medial, and final position, and the errors children make most often, plus 8 games for practicing it.
Example Z words: zebra, zero, zigzag, zip (beginning); amazing, buzzer, cousin, daisy (middle); bees, breeze, buzz, cheese (end).
The /Z/ sound is a voiced alveolar fricative and the voiced counterpart of /S/. It is produced in the same tongue position as /S/ (tongue tip near the ridge behind the upper teeth), but with the vocal cords vibrating. It appears in words like "zoo," "fuzzy," and "nose."
How to Make the Z Sound
Place your tongue in exactly the same position as for /S/: tongue tip just behind the upper front teeth, near the alveolar ridge. Keep your teeth close together. Now turn your voice on — you should feel a buzzing vibration. The sound should be like a buzzing bee: "zzzzz."
IPA Symbol: /z/
Most children master the /Z/ sound by age 4-5. Since it uses the same mouth position as /S/ with added voicing, it typically develops around the same time or shortly after /S/ is mastered.
Common Z Sound Errors
- Devoicing: saying /S/ instead of /Z/ (e.g., "soo" for "zoo")
- The same lisp patterns seen with /S/ (frontal or lateral lisp)
- Substituting /D/ for /Z/ (e.g., "doo" for "zoo")
- Not maintaining voicing throughout the word
- Omitting /Z/ at the end of words and plurals

How to Practice Z Words at Home
Evidence-based strategies parents can use to support /Z/ sound practice.
If your child can say /S/, teaching /Z/ is often as simple as "turning the voice on." Have them say /S/ and then hum at the same time.
Use the "buzzing bee" cue: have your child pretend to be a bee flying around and buzzing "zzzzz."
Place a hand on the throat to feel the vibration for /Z/ versus no vibration for /S/.
Practice /S/-/Z/ pairs: sip/zip, sue/zoo, sink/zinc, seal/zeal.
Since /Z/ appears at the end of many plurals (dogs, cows, bees), practice adding /Z/ to plural words.
Play "buzzing" games: move a toy bee around and buzz /Z/ whenever the bee lands on something.
If your child has a lisp on /S/, fix that first — /Z/ will often follow since it uses the same tongue position.
