Speech Development

To put it simply, speech development refers to the pronunciation of sounds. It may also be called articulation or articulation development. How a person says sounds depends on movement and placement of the tongue, teeth, jaw, breath, and voice box.  

Now, how sounds develop and deciding if a child has a delay or disorder is a bit more complicated and is dependent on many factors.

When Do Sounds Develop?

Speech develops in a continuum. Some sounds are much easier to say than others. For example, motorically speaking, 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. Again, the decision for therapy will depend on many factors such as the type of errors, errors across context/placement in words, stimulability, and more!

Speech Development Milestones

Speech therapists use speech development milestone charts to decide if a child needs therapy. They also use those charts to create treatment goals and to monitor progress.

Speech Intelligibility

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.

The newest research by  McLeod, S. & Crowe, K. (2018) indicates that 85% of 3-year-olds are 80% intelligible.
