About the TH Sound

Background information to help you support your child's speech development.

The /TH/ sound has two versions: the voiceless /TH/ (as in "think" and "bath") and the voiced /TH/ (as in "this" and "the"). Both are produced by placing the tongue between or just behind the upper front teeth and letting air flow over the tongue. These are among the most commonly misarticulated sounds in English.

Most children master the voiceless /TH/ (as in "think") by age 5-7 and the voiced /TH/ (as in "this") by age 5-7 as well. It is common for children to substitute /F/ or /D/ for /TH/ during early development.

How to Practice TH Words at Home

Evidence-based strategies for getting the most out of word list practice.

1

Start with just 5 words at a time. Short, focused practice sessions (5-10 minutes) are more effective than long ones.

2

Say each word slowly and clearly so your child can hear the /TH/ sound. Exaggerate the sound slightly.

3

Practice words in all three positions (initial, medial, final) but focus on whichever position your child finds easiest first.

4

Once individual words are easy, combine them into short phrases and sentences for carryover practice.

5

Use a mirror during practice so your child can see their mouth movements and compare them to yours.

6

Keep it fun — turn the word list into a game, use stickers as rewards, or practice during everyday activities.
