Speech Sound Production

  • Speech sound production or articulation is the process of using the lips, tongue, teeth, palate, and airflow to produce the sounds we hear in speech. It is important to correct speech sound errors as early as possible, so they do not become life long habits. 

  • Children typically develop the ability to produce all speech sounds correctly by age nine. A speech therapist becomes concerned when a child passes the typical age of mastery for a given sound, but still exhibits difficulty producing it in isolation, words, sentences, or conversation. Below is a list of speech sound production by developmental age. 

Your child should be able to produce these sounds by the following ages:

Age 5
: m, h, w, n, p, b, d, g, k, y (as in yes), f

Age 6
: t, ng, l

Age 7
: ch, sh, j (as in jump), th (voiceless as in thing, thumb)

Age 8
: s, z, v, r, th (voiced as in this, that)

These are UPPER age limits of customary consonant production in which 90% of all children are producing these sounds. We frequently will work on sounds a little earlier or later depending on developmental levels of the specific children with whom we are working. If you have any questions please feel free to refer for a screen.
