Since I’ve been trying to post more about how to teach speech sounds, I thought it would be helpful to post this chart which shows the ranges of speech sound development. Using these norms, you can see when you should expect your child to correctly produce the consonant sounds in our English language. There is range of “normal” speech sound development.
As you look at the chart, the left side represents the age at which 50% of kids are correctly producing that sound. The far right side of the of the colored bar represents the age at which 90% of kids are able to correctly say that sound.
Hopefully, you will be able to use this chart to give you an idea of what sounds come in first and those that don’t emerge until later.
