Concerned about stopping in your child’s speech?

If your child replaces sounds like /f, s, sh, z/ with /p, t, d/, they may be showing the stopping phonological process. Get clear, parent-friendly insight on what these speech sound patterns can mean and what support may help.

Answer a few questions about the sound swaps you’re hearing

This quick assessment focuses on stopping speech sounds, including when a child replaces fricatives with stops. You’ll get personalized guidance based on your child’s speech patterns and age.

What is stopping in speech development?

Stopping is a phonological process where a child replaces a continuous sound, such as /f/, /s/, /sh/, or /z/, with a stop sound like /p/, /t/, or /d/. For example, a child might say “tun” for “sun” or “doo” for “zoo.” In early speech development, some stopping errors can be part of normal learning. If the pattern continues beyond expected ages or affects how well others understand your child, speech therapy for the stopping process may be helpful.

Common examples of stopping speech sounds

/s/ becomes /t/

A child may say “tea” instead of “sea” or “tun” instead of “sun.” This is one of the most common stopping speech sounds examples parents notice.

/f/ becomes /p/

You might hear “pan” for “fan” or “pish” for “fish.” This can happen when a child is not yet using airflow for fricative sounds.

/z/ or /sh/ becomes /d/ or /t/

Examples include “doo” for “zoo” or “tip” for “ship.” These patterns can make speech harder to understand in everyday conversation.

When stopping may need extra support

The pattern happens often

If your child is stopping sounds in speech almost every time, it may be more than an occasional speech development error.

It affects intelligibility

When family members, teachers, or other children have trouble understanding your child, stopping in child speech therapy may be worth exploring.

It continues as your child gets older

Some stopping patterns fade with development, but persistent use can point to a phonological disorder or a stopping articulation disorder that deserves closer attention.

How speech therapy helps with the stopping phonological process

Speech therapy for stopping process usually focuses on helping a child hear the difference between stop sounds and fricatives, then practice producing the target sounds in words, phrases, and conversation. A speech-language pathologist may also look at whether the pattern is isolated or part of a broader speech sound disorder. If you’re wondering how to stop stopping phonological process patterns at home, the best first step is understanding exactly which sounds your child is replacing and how often it happens.

What you’ll get from this assessment

Topic-specific insight

The assessment is focused on stopping error in speech development, not general speech concerns.

Personalized guidance

You’ll get next-step guidance based on the sound patterns you’re noticing, including whether the pattern may fit stopping phonological process concerns.

Clear language for parents

We explain what it means when a child replaces fricatives with stops, so you can feel more confident about what to watch for next.

Frequently Asked Questions

What is the stopping phonological process?

The stopping phonological process happens when a child replaces fricative or affricate sounds, which require continuous airflow, with stop sounds made by briefly blocking airflow. For example, “sun” may become “tun,” or “fan” may become “pan.”

Is stopping ever normal in speech development?

Yes. Some stopping can appear in typical early speech development as children learn harder sounds. The main concern is whether the pattern is still present beyond expected ages, happens across many sounds, or makes your child difficult to understand.

What does it mean if my child replaces fricatives with stops?

When a child replaces fricatives with stops, it may suggest a phonological pattern rather than a single sound mistake. That means your child may be using a rule across groups of sounds, which is why identifying the pattern clearly is important.

Is stopping an articulation disorder or a phonological disorder?

It can be described either way depending on the child’s full speech profile, but stopping is most commonly discussed as a phonological process. A speech-language professional looks at whether the issue is one sound, several sounds, or a broader sound pattern system.

How do I know if my child may need speech therapy for stopping process patterns?

If the stopping pattern happens frequently, affects everyday understanding, or continues as your child gets older, it may be time to seek guidance. A focused assessment can help you decide whether monitoring, home support, or formal speech therapy may be the right next step.

Get personalized guidance for your child’s stopping pattern

If you’re noticing repeated sound swaps like /s/ to /t/ or /f/ to /p/, answer a few questions to get guidance tailored to your child’s speech. It’s a simple way to better understand whether the stopping process may need extra support.
