By 18 months a
child's speech is normally 25% intelligible
By 24 months a child's speech is normally 50 -75% intelligible
By 36 months a child's speech is normally 75-100% intelligible

Intelligibility to
Parents (18-36 months)
Table 1, above, provides
a rough rule of thumb for how clearly a child should be speaking in the
age-range 18 to 36 months. It is important to bear in mind that there is
considerable individual variation between children. If, as a parent, you
are in doubt about your own child's speech sound development or speech
clarity, an assessment by a speech-language pathologist will quickly
tell you if your child is 'on track' and making the right combination of
correct sounds and 'errors' for their age.
