Articulation vs. Phonological Disorders: What’s the Difference?
Many parents notice their child having difficulty being understood, but not all speech sound errors are the same. Understanding the difference can help families know what support their child may need!
🔹 Articulation Disorder
This occurs when a child has difficulty producing individual speech sounds correctly. Examples may include:
• Substituting one sound for another (“red” → “wed”)
• Leaving sounds out (“hand” → “and”)
• Adding extra sounds (“black horse” → “buhlack horse”)
These errors are often related to the physical production of speech sounds.
🔹 Phonological Disorder
This occurs when a child uses patterns of sound errors that affect entire groups of sounds. Examples may include:
• Fronting (“key” → “tee”)
• Weak syllable deletion (“banana” → “nana”)
• Cluster reduction (“block” → “bock”)
• Final consonant deletion (“bus” → “bu”)
These errors are related to how a child organizes and understands speech sounds.
While both can impact a child’s intelligibility, they require different approaches in therapy. Early identification and intervention can make a significant difference in communication skills and confidence.
If you’re concerned about your child’s speech development, a speech-language evaluation can help determine the underlying cause and create a plan for success.
