Slurred Speech, Epenthesis

By Pam Marshalla

Boy with ToyQ: My male client is five years of age. He has developmental artic errors and slurred speech. He also add a schwa at the ends of words: “Baby” is “baby-uh” and “Sand” is “Sand-uh.” What would account for this and how would you address this kind of speech sound error?

Developmental errors are normal in a five year old but slurred speech is not. Something is going on. This sounds like mild dysarthria.

I see the addition of the schwa at the end of words as a part of normal development. Toddlers always add a schwa to the end of words to make one-syllable CVC words into easier-to-pronounce two-syllable CV-CV words. Examples: “Dad” changes to “dada”; “Mom” changes to “mama”; and “Dog” changes to “Do-guh.”

The CV is the simplest syllable in terms of motor control.  It is the canonical syllable, meaning that it is the most fundamental. The CVC is more difficult. Your client may still be adding the schwa to words because phonologically and motorically he is still operating at that level.

I have seen this many times. I usually play with the words both ways.  We over-practice the incorrect production to help him hear it, and then we learn the new way, and then we play back-and-forth between the two.

  1. What about 8, 9, and 10 year olds who add a schwa to the end of words? Or to the middle of words? I have 3 at my school. It actually seems to be more of a fluency issue at this point. It gets worse when they are tense or excited. Do you have any ideas for that? Thanks, Kristin Pruett

    1. I see the addition of a schwa as the child’s way of making a simpler motor pattern.

      The CV is the simplest motor pattern.
      Therefore change a CVC to a CV-CV to make it easier.
      All kids do this, e.g., “mom” changes to “mama,” and “dad” changes to “dada.”
      They also do this with the diminutive — “dog” changes to “doggie” and Cat” changes to “kittie.”

      Therefore adding the schwa is a strategy to help them learn new motor patterns.
      I actually TEACH my clients to add a schwa before I teach them final consonants.
