Speech Delay

Child with letters

Speech delay is when a child is behind in their development of clear speech. This is different to language delay. For example, a child with a speech delay may have an age appropriate vocabulary but be difficult to understand, whereas a child with a language delay might say a few words clearly but at their age should be speaking in sentences. It is possible to have one without the other or both together.

Some speech delays may be due to a physical problem such as a cleft palate or a hearing impairment, but most children have no specific reason for their speech delay.

It is common for young children to shorten words eg. ‘nana’ instead of banana, leave off a sound eg. ‘poon’ instead of spoon, and substitute sounds in words eg. ‘w’ instead of ‘r’ in rabbit, ‘f’ instead of ‘th’ in thing, ‘f’ instead of ‘tr’ in truck (this can be a little embarrassing, especially if your kid loves trucks). But as a child gets older, their speech should become clearer and these ‘mistakes’ should disappear.

If a child continues to have problems pronouncing sounds they are considered to have a speech disorder and should be seen by a speech pathologist. The most commonly mispronounced sounds are ‘s’, ‘l’, ‘r’ and boys are more likely than girls to have difficulty pronouncing sounds.

Speech development

Children master some sounds earlier than others. This is a general guide for what most children are able to do by a certain age.

By 2 years

Can say sounds: ‘t’ (tea), ‘d’ (dog), ‘n’ (nose), ‘m’ (mummy), ‘b’ (ball)

Will still have difficulty using sounds correctly in words

An unfamiliar person should be able to understand 50% of what your child is saying

Additional sounds: ‘b’ (ball), ‘p’ (pig), ‘m’ (mummy), ‘h’ (horse), ‘k’/’c’ (cup), ‘g’ (girl), ‘ng’ (sing), ‘w’ (water), ‘y’ (yellow)

An unfamiliar person should be able to understand 75% of what your child is saying

By 6-7 years

Additional sounds: ‘v’ (van), ‘th’ (this), ‘th’ (thing), ‘zh’ (treasure)

Usually by the age of 7 a child will be using all sounds correctly

Tips to help your child

  • Respond to any of your child’s attempts at communication

  • Talk and read to your child to help develop their speech, language and listening skills

  • Sing nursery rhymes

  • When you're reading to your child point out the letters and sounds in words that are difficult

  • Try not to overcorrect (nag) or be negative eg. ‘you’re saying it wrong’

  • Be positive and emphasis the sound that is incorrect eg. ‘ssssing’

  • Don’t let friends or relatives (especially older siblings) make fun of your child

  • Let your child see your mouth movements as you are saying the sounds/words

  • Be a role model - speak clearly and use correct speech sounds

Seek professional help if your child:

  • is >6 months behind in approx. age range for using speech sounds

  • gets frustrated about speaking eg. is not easily understood, stutters, has trouble finding the right words

  • has a hearing loss

  • has problems in other areas of development eg. motor skills, social interaction

NOTE: This is only a guide. The ages at which children master speech sounds varies. If you have any concerns about your child’s speech, consider an assessment with a speech pathologist. If you are concerned about a hearing problem or you think your child has a delay in other areas of development as well as speech, see your doctor.
