Thinkabara🗓️ Speech sound development chart
At what age do children learn to say each sound? This chart shows the age by which about 90% of American English–speaking children produce each consonant, plus common "kid speech" patterns and when they usually fade.
| By age | Most children (about 90%) say |
|---|---|
| 2 to 3 years | b, n, m, p, h, w, d |
| 3 to 4 years | g, k, f, t, ng (as in sing), y (as in yes) |
| 4 to 5 years | v, j (as in jump), s, ch, l, sh, z |
| 5 to 6 years | r, voiced th (as in this), zh (as in measure) |
| 6 to 7 years | voiceless th (as in thumb) |

Common patterns (phonological processes)
Young children simplify words in predictable ways. These patterns are normal until about the ages below.
| Pattern | Example | Usually gone by |
|---|---|---|
| Fronting | "tat" for cat, "doe" for go | about 3½–4 |
| Stopping | "tun" for sun, "pan" for fan | about 3–5 (depends on the sound) |
| Final consonant deletion | "ca" for cat, "bo" for boat | about 3 |
| Cluster reduction | "top" for stop, "pane" for plane | about 4 |
| Gliding | "wabbit" for rabbit, "yeyo" for yellow | about 5–6 |
| Weak syllable deletion | "nana" for banana | about 4 |
Practice these patterns with minimal pairs.

When to ask for help
- Your child is past the age range for a sound or pattern above.
- Familiar people often can't understand your child after age 3, or strangers after age 4.
- Your child gets frustrated or avoids talking.
- You notice a lisp where air comes out the sides of the tongue (it sounds "slushy") — this pattern is not part of typical development.
A licensed speech-language pathologist can evaluate your child. Evaluations are free through Early Intervention (under 3) and your public school district (3 and older).
Frequently asked questions
At what age should a child say all sounds correctly?
Most children produce all English consonants by around age 6–7. Sounds like R and TH are among the last. Many children make some errors until then, which is normal.
Why do different charts give different ages?
Older charts used different studies and different cut-offs (50%, 75% or 90% of children). This chart uses a 2020 review of 15 US studies (Crowe & McLeod) and shows the age by which about 90% of children produce each consonant.
Should I worry if my 3-year-old says "wabbit"?
No. Saying W for R (gliding) is common until about age 5–6. What matters more at 3 is that familiar people understand most of what your child says.
How clear should my child's speech be?
A common rule of thumb: strangers understand about half of what a 2-year-old says, about three-quarters at age 3 and nearly everything by age 4, even if some sounds are still wrong. If you or others often can't understand your child, ask for an evaluation.
