What should a 4-year-old's speech be like?
At age 4, children should be nearly 100% understandable to strangers. Most phonological processes like fronting and stopping should be gone. Gliding (R and L sounds) may still be developing.
Speech Terms for 4-Year-Olds
By age 4, most phonological processes should be resolved. Learn what's expected and when speech therapy might help.
✓ What's Normal at Age 4
- •Gliding of R (saying "wabbit" for "rabbit") - normal until age 6-7
- •Gliding of L (saying "yeyo" for "yellow") - resolving by age 5
- •Some difficulty with TH sounds - normal until age 6-7
- •Complex blends like STR may still be developing
When to Seek Evaluation
- ⚠Still fronting (should have resolved by now)
- ⚠Still stopping (should have resolved by now)
- ⚠Less than 75% understandable
- ⚠Difficulty with sounds other than R, L, TH
- ⚠Inconsistent speech errors (possible apraxia sign)
- ⚠Avoiding speaking or frustrated by communication
Trust your instincts. Early evaluation is always better than waiting.
