Advice and resources : Typical speech sound development

Overview

Children develop speech sounds over time, with words gradually sounding more like the adult version. 

What you might see

The following is the typical pattern of developing speech sounds.

By two years, sounds typically used are:

• b, d, m, n, w
• a range of vowel sounds

Some two-year-olds might have difficulties with:

• all other sounds, including k, g, s, f, sh, l, r
• missing consonants at the ends of words
• long complex words that are difficult to say, such as helicopter

By two and a half years, sounds typically used are:

• p, b, t, d, m, n, w

Some two-and–a-half-year-olds might have difficulties with:

• all other sounds, including k, g, s, f, sh, l, r,
• long complex words that are difficult to say

By three years, sounds typically used are:

• p, b, t, d, m, n, w, h

Some three-year-olds might have difficulties with:

• All other sounds including: k, g, s, f, sh, l, r,
• Long complex words that are difficult to say

By three and a half years, sounds typically used are:  

• p, b, t, d, m, n, w, h
• ppssibly starting to use k, g, s, f

Some three-and-a-half-year-olds might have difficulties with:

• sh, z, v, ch, j, l, r, th
• two consonants together (clusters), like fl, sp, sm, gr, str
• long complex words that are difficult to say

By four years, sounds typically used are:  

• k, g, s, f, p, b, t, d, m, n, w, h
• 's' clusters, such as sm, sp, sn, st, sk

Some four-year-olds might have difficulties with:

• sh, z, v, ch, j, l, r, th
• other consonant clusters, such as fl, fr, gr, gl, str, and spl
• some longer, more complex words

By four and a half years, sounds typically used are:  

• sh, ch, j (in addition to other sounds listed above)

Some four-and-a-half-year-olds might have difficulties with:

• l, r, th
• consonant clusters, such as fl, fr, gr, gl, str, and spl

By five years, sounds typically used are:

• now using l (in additional to other sounds listed above)

Some five-year-olds might have difficulties with:

• r, th
• consonant clusters involving r or l, such as fl or gr

By six years sounds typically used are:

• using all sounds except th
• using clusters of three consonants, like spr, str, and spl

Some six-year-olds may have difficulties with:

• th

By seven years, most children are able to use all sounds except for regional accent variations, such as “fink” for think.

Concerns about speech

Concerns about speech

The following areas often worry parents, carers and teachers. But they’re all perfectly normal and don’t need treatment by a Speech and Language Therapist.

• Lisping in children under seven, when a “th” sound replaces the letter “s”, usually disappears as children get older – lost teeth or braces might also cause lisping; this is perfectly normal
• Saying “w” instead of “r” can persist up until the age of seven, although most children will have acquired the “r” sound by the age of five
• Leaving out the “t” in the middle and at the end of words isn’t a problem unless your child is showing other speech problems – leaving out “t” is often caused by an accent, rather than a problem with talking
• Replacing “th” with “f” (in words such as “thing”) and “th” with “v” (in words such as “that”) is usually caused by accent, rather than speech difficulties

If you notice any of these in your child after the age of seven, and they seem to be causing difficulties, consider contacting your GP or our Ways to refer HealthHub for advice.

Online language development workshops

Our team run online workshops on early language development. They are designed for parents and carers and those working within early years settings. We have three training sessions available on different topics to equip you with everyday strategies to support your child, aged up to five.

The Department of Education has created a resource called Hungry Little Minds to help support parents and carers with tips to encourage speech, language and development in age appropriate stages.
