Speech development refers to the pronunciation of sounds. It may also be called articulation. How a person says sounds depends on movement and placement of the tongue, teeth, jaw, and voice box.
When Do Sounds Develop?
Speech develops in a continuum. Some sounds are much easier to say than others. For example, it is easier to say "b" than "r." Therefore, we expect that a child will learn to say "b" correctly before he can say "r" correctly. If a child is not saying a sound by a certain age, he or she may need speech therapy in order to learn that sound.
How to use this chart: Below you will see a chart listing ages and sounds. First find the age of your child on the left. Then look to the corresponding row for what sounds he or she should be saying. Your child should be able to say these sounds "most of the time," about 90%. An error here or there is okay and normal.
If your child is not saying the sounds listed by their age, it doesn't necessarily indicate there is a problem.
However, if you want to start working on sounds right away read our speech activities for home practice ideas. It is a great place to start! Playing games with your child and modeling correct speech is always a good idea :)

What is speech intelligibility?
Speech intelligibility is another important factor to consider. Intelligibility is how well someone understands what you are saying.
It is best to judge intelligibility by an unfamiliar listener since as parents, we are experts at understanding our children’s “own” language.
How to use this chart: Your child still may not be saying all of his sounds correctly by 4 years of age (for example, r, l, z). But, even with these errors, an unfamiliar listener should understand what he is saying 100% of the time!
