TH Sound Activities for Children
The /th/ sound comes in two varieties — voiceless (as in "think") and voiced (as in "the"). Many children substitute /f/ or /d/ for /th/ (saying "fink" instead of "think" or "da" instead of "the"). This is one of the later-developing sounds in English.
Why This Is Challenging
The /th/ sound requires placing the tongue between or just behind the front teeth — a position that feels unnatural to many children. Because /th/ develops later (ages 6-8), it can be hard to know when to seek help versus when to wait.
How Verbalyft Helps
Verbalyft provides targeted /th/ stories and games that naturally include high-frequency /th/ words (the, this, that, think, three). Real-time feedback helps children feel the difference between /th/ and substitute sounds like /f/ or /d/.

Frequently Asked Questions
When should my child be able to say /th/?
The /th/ sound is one of the last to develop, typically mastered between ages 6-8. Substituting /f/ or /d/ for /th/ before this age is developmentally typical.
What's the difference between voiced and voiceless /th/?
Voiceless /th/ (as in 'think,' 'three') has no vocal cord vibration. Voiced /th/ (as in 'the,' 'this,' 'that') vibrates the vocal cords. Children may struggle with one or both.
