Check any sound by age →How to use these Z word lists
/z/ is the voiced partner of /s/. Children often devoice it — saying sue for zoo — and the same frontal and lateral lisp patterns that affect /s/ affect /z/ too.
The lists check where /z/ appears in each pronunciation, not just the spelling. They do not choose a treatment target or replace clinical judgment.
