What is phonological disorder in speech therapy?

When a child has patterns of sound errors affecting groups of sounds—not just individual sounds. Different from articulation disorders (single sounds). Phonological disorders involve the "rules" of sound use.

Example

⚠️ When to Seek Help

Consider consulting a speech-language pathologist if:

  • Your child is frustrated or avoids speaking
  • Others have difficulty understanding your child
  • You notice regression (losing skills they had)
  • Your gut tells you something isn't right

Trust your instincts. Early evaluation is always better than waiting.

What is a phonological disorder?▼

A phonological disorder involves patterns of errors affecting groups of sounds. Instead of struggling with just "k," a child might front ALL back sounds (k→t, g→d). It's about the "rules" of sound use, not individual sound production.

How is phonological disorder different from articulation disorder?▼

Articulation = difficulty with specific sounds (motor issue). Phonological = patterns affecting sound groups (language issue). A child with articulation trouble might struggle with "s." A child with phonological issues might delete ALL final consonants.

Phonological Process

A predictable pattern children use to simplify adult speech. Fronting, stopping, gliding—these are all normal and disappear by certain ages. Only a concern if they persist too long.

Speech Sound Disorder

When a child has ongoing difficulty producing speech sounds correctly, making their speech hard to understand. This is different from normal developmental patterns that resolve on their own.

Articulation

How clearly your child produces individual speech sounds. It's the physical ability to move the tongue, lips, and jaw to make sounds correctly. Different from phonology, which is about sound patterns.
