What to listen for
Devoicing is the main error — "meashure" for "measure" — which means the mouth is already right and only the voice is off, and a hand on the throat settles that in seconds. J is the other substitution, but check the word before treating it as an error: plenty of English speakers genuinely say "garaj", and "beige" and "massage" go the same way, so it only counts if the swap also shows up in "measure", "vision" and "treasure". Note too that ZH essentially never opens an English word, so the first list here is words where it arrives as early as it can, at the start of the second syllable.
Common ZH errors
- Devoicing: saying /SH/ instead of /ZH/ (e.g., "meashure" for "measure")
- Substituting /J/ (e.g., "garaj" for "garage" or "vidgeon" for "vision")
- Substituting /Z/ (e.g., "treazure" for "treasure")
- Stopping the airflow so the sound starts with a /D/ press instead of buzzing continuously
- Losing the sound entirely inside longer words (e.g., "telvision," "decidion")
How to run ZH practice
Short and frequent beats long and occasional. Five to ten minutes on most days produces more correct ZH productions over a fortnight than one long weekend session, and it is far easier to sustain.
Work in one position at a time. ZH essentially never starts an English word — only French borrowings like “genre” do, so start with the list where it arrives earliest, then work outwards to the middle and at the end — mixing all three from the start usually slows everything down.
Keep correction light. Model the word correctly and move on rather than asking for a repeat every time; a child who feels tested talks less, and less talking is the opposite of what ZH practice needs.
Tips for the ZH sound
- Start from /SH/, which most children already have. Have them hold a long "shhh," then turn the voice on without moving anything: "shhh" becomes "zhhh."
- Put a hand on the throat to feel the difference — no vibration for /SH/, a steady buzz for /ZH/.
- Practice in the middle of words first, since that is where nearly every /ZH/ word lives: "mea-sure," "vi-sion," "trea-sure," "u-sual."
- Use the "-sion" and "-sure" spelling patterns as a word-finding shortcut. Once your child can say "vision," "decision," "division," and "television" follow quickly.
- Contrast /ZH/ with /J/ using the pair "lesion / legion," and with /SH/ using near-pairs like "Confucian / confusion" and "dilution / delusion."
- Save the French borrowings ("garage," "beige," "rouge," "massage") for last. They are the only place /ZH/ ends a word, and many American speakers say some of them with /J/ anyway.
- Because /ZH/ is so rare, build practice into a few reliable everyday phrases — "my favorite television show," "a treasure hunt," "good decision" — rather than hunting for new words.
