The /K/Sound: Speech Therapy Guide & Practice Games

The /K/ sound is a voiceless velar stop (also called a plosive). It is produced by raising the back of the tongue to touch the soft palate (velum), briefly stopping the airflow, then releasing it in a quick burst. It is one of the earlier-developing back sounds.

How to Make the /K/ Sound

Raise the back of your tongue up to touch the soft part of the roof of your mouth (the velum or soft palate). This blocks the airflow briefly. Then quickly drop the back of your tongue to release a burst of air. The front of your tongue stays down and relaxed behind your lower teeth. Your voice stays off — /K/ is a quiet, popping sound.

IPA Symbol: /k/

Most children master the /K/ sound by age 3-4. It is one of the earlier-developing velar sounds and is typically acquired around the same time as /G/.

Tips for Practicing the /K/ Sound at Home

Evidence-based strategies parents can use to support /K/ sound practice.

1

Use the "coughing" cue: a small cough naturally engages the back of the tongue, which is the same position needed for /K/.

2

Have your child lie on their back — gravity helps the tongue fall backward, making it easier to produce back sounds like /K/.

3

Gently press under your child's chin (behind the jaw) to discourage the tongue tip from lifting, encouraging the back of the tongue to do the work.

4

Use a tongue depressor or popsicle stick to hold the tongue tip down while your child practices pushing the back of the tongue up.

5

Practice "gargling" with water to help your child feel the back of the tongue engaging.

6

Start with /K/ at the end of words ("bake," "book") as many children find this position easier.

7

Use fun "K" words your child enjoys: "cookie," "cake," "kite," "kitten," "kangaroo."

Frequently Asked Questions About the /K/ Sound

Common questions parents ask about the /K/ sound in speech therapy.

When should my child be able to say the /K/ sound?expand_more
Most children master the /K/ sound by age 3-4. If your child is still replacing /K/ with /T/ (called "fronting") after age 4, it is a good idea to consult a speech-language pathologist.
What is fronting?expand_more
Fronting is when a child uses a front sound (/T/ or /D/) in place of a back sound (/K/ or /G/). For example, saying "tat" instead of "cat" or "dame" instead of "game." It is a normal developmental pattern up to about age 3-4 but should resolve by then.
Why can my child say /K/ in some words but not others?expand_more
Certain vowel combinations make /K/ easier or harder. /K/ before back vowels (like "coo" or "go") is often easier because the tongue is already near the back of the mouth. /K/ before front vowels (like "key" or "cap") may be harder because the tongue must quickly move from front to back.
How do I teach the difference between /K/ and /T/?expand_more
The key difference is where the tongue touches. For /T/, the tongue tip touches behind the upper front teeth (front of the mouth). For /K/, the back of the tongue touches the soft palate (back of the mouth). Use a mirror and a flashlight to show your child where the tongue should be.
Can the lying-down trick really help?expand_more
Yes, having your child lie on their back can help with /K/ production. Gravity naturally pulls the tongue backward, making it easier for the back of the tongue to make contact with the soft palate. Once your child gets the feel for /K/ in this position, gradually transition to sitting and standing.
