Speech sound disorders

Clearer sounds. More confidence.

Some children say sounds incorrectly, leave sounds out, or swap one sound for another long after their friends have stopped. Speech sound disorders mean difficulty making certain sounds correctly, or planning the movements speech needs. They can make a child hard to understand and affect confidence and, later, reading and spelling.

Signs parents notice

  • People outside the family often can’t understand your child
  • Sounds are missing or swapped (“tat” for “cat”)
  • A lisp, or sounds that stay unclear well past the age most children master them
  • The same word said differently each time, or more errors on longer words
  • Frustration when others don’t understand

What we work on

We work on the sounds your child has trouble making, such as “r,” “s,” “l,” “sh” or “th,” and on sounds that are left out or swapped for others. Therapy starts with hearing and making the sound correctly, then builds from single sounds to words, sentences and everyday conversation, with short practice at home.

Some children have weak or poorly controlled speech muscles (dysarthria), which can follow cerebral palsy, a brain injury or another neurological condition. Speech may sound slurred, quiet or strained. Therapy builds control and breath support and gives other ways to be understood while speech develops.

Childhood apraxia of speech

A speech delay follows the usual sequence of sound development, only more slowly. Apraxia is a problem with movement planning, so signs include:

  • Little babbling as a baby, and first words that came late
  • The same word said differently each time
  • More errors on longer words and sentences
  • Visible searching with the mouth before a word

Therapy uses frequent, structured practice of speech movements with cues that are gradually faded.

When to get an evaluation

Children develop sounds at different speeds, and some, like “r,” come later. Consider an evaluation if strangers have trouble understanding your child by around age 3 to 4, if their speech is unclear for their age, or if it is affecting how they feel about talking.
