As a parent, there’s nothing quite like hearing your child’s voice. You celebrate every new sound and word. But what happens when their speech is hard to understand? When you know what they’re trying to say, but family members or teachers struggle to catch on? This can be frustrating for both you and your child.

At Michigan Pediatric Therapy, we get it. We’re a leading provider of pediatric speech therapy in southeast Michigan, and we know that unclear speech is a common concern for families. We’ve helped countless children in Farmington Hills, MI, and the surrounding areas find their voice. When a child has difficulty with speech sounds, it often falls into one of two categories: articulation disorders or phonological disorders.

While both can make a child’s speech difficult to understand, they are very different problems that require different therapy approaches. This guide will help you understand the key differences between these two speech sound disorders, what to look for, and how our expert speech-language pathologists (SLPs) can help your child speak more clearly and confidently.

Think of an articulation disorder as a physical problem with making a specific sound. The child knows what they want to say, and their brain knows what sound to use, but they just can’t get their mouth, tongue, or lips to form that sound correctly.

Imagine your child is learning to play the guitar. An articulation error is like them putting their fingers in the wrong place on the fretboard, resulting in a single, incorrect note. The rest of the song might be perfect, but that one note is off.

Common signs of an articulation disorder include:

With an articulation disorder, the errors are usually consistent across different words. The child will likely have trouble making the same sound, like the /r/ sound, every time it appears in a word. For example, they may struggle with rabbit, car, and story.

This type of issue is often what people think of when they hear “speech therapy.” An SLP helps a child’s mouth and tongue learn how to make the specific sound correctly. It’s very targeted and focused on the physical act of producing speech. We’ve had great success with speech therapy for lisps and helping kids master tricky sounds like /r/, /l/, and /k/.

Now, let’s look at phonological disorders. This isn’t a problem with physically making a sound, but rather a problem with the rules of speech in the child’s mind. The child’s brain has developed a simplified system for using sounds, which leads to predictable error patterns.

Going back to our guitar analogy, a phonological disorder is like the child’s brain deciding that all songs should only use three chords. They can physically play all the notes correctly, but they’re following a simplified rulebook in their head, so the song comes out sounding very different from how it should.

Common signs of a phonological disorder include:

• Sound Omissions: The child consistently leaves off the final sound of a word, saying do for “dog” or cu for “cup.” This is a pattern, not a single sound error.
• Sound Substitutions: The child replaces a group of sounds with another, often based on where the sound is made in the mouth. A common pattern is fronting, where sounds made in the back of the mouth (/k/, /g/) are replaced with sounds made in the front (/t/, /d/). For example, saying tate for “cake” or doggie for “goggie” (not a real word, but a common phonological process).
• Simplifying Consonant Clusters: The child leaves out a sound in a group of two or more consonants, saying poon for “spoon” or tory for “story.” This is a classic example of “unclear speech in children.”

The key difference here is the pattern. A child with an articulation disorder might struggle with just the /s/ sound, but a child with a phonological disorder might replace all sounds made in the back of the mouth with front sounds, or always leave off the last sound of a word. These patterns make their speech very hard for unfamiliar listeners to understand.
Our speech-language pathologists treat phonological disorders by helping a child’s brain “unlearn” these simplified rules and replace them with the correct adult sound system. It’s about retraining the brain’s internal map of sounds, not just the mouth’s movements.

It’s important to remember that all children make speech errors as they learn. It’s a normal part of development! So, how do you know when it’s time to seek help?

Here’s a general timeline for when most children master certain sounds:

• 2-3 years old: p, b, m, d, n, h, t, k, g, w, f, y
• 4 years old: l, s, z, sh, ch, j, v
• 5-6 years old: r, th (as in “this”), ng, zh (as in “vision”)
• 7-8 years old: th (as in “thin”)

If your child is consistently making errors on sounds long after the typical age of mastery, or if their speech is very difficult for others to understand (even for familiar people), it might be time for a speech and language evaluation.
