About the ST Blend

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

The /st/ blend joins the /s/ and /t/ sounds — the "st" in star, stop, stand and story. It is also one of the most common ways English ends a word (fast, best, most), so it is worth practising at both ends of the word.

Most children master the /st/ blend by age 5. Blends arrive after the sounds they are made of: the /S/ and /T/ sounds each have to be reliable on their own before the cluster will hold, which is also the order to practise them in. Two-sound blends are generally in place somewhere between ages 4 and 7, tracking the sounds inside them — the ones containing /L/ or /R/ come in later than the rest.

How to Practice ST Blend 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 /st/ 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.
