K Sound Words
The K sound is a voiceless 'back' sound made with the back of the tongue.
Age of acquisition. Most children produce K clearly between ages 3 and 4. Norms vary between children and between sources, so treat this as a rough guide, not a deadline. If you have concerns, an SLP can assess.
How to make it. Lift the back of the tongue up to the roof of the mouth, then release. A common early swap is T for K (saying 'tea' for 'key').
How to practice the K sound at home
- Start at the word level, then move to short phrases and sentences once the K sound is easy on its own.
- Practice in short, frequent bursts. Five focused minutes a day beats one long weekly session.
- Model it first: say the word slowly, stretch the K sound so your child can hear it, then have them copy you.
- Use the picture cards to keep it playful, and praise good tries, not just perfect ones.
