Gliding and Speech Therapy

Gliding is a common phonological process seen in children with phonological delays. On this page, you’ll find a clear explanation of what gliding is, when it is considered typical versus disordered, and how it can be effectively treated in speech therapy.

What is gliding?

Gliding occurs when a liquid sound (/r/ or /l/) is replaced with a glide (/w/ or /j/ “y”).

Examples:

• red → wed
• lamp → yamp

While this definition is simple, effective treatment requires a deeper understanding of how liquids and glides differ phonologically and phonetically.

Liquids (/r/ and /l/):

• Sonorant sound: sound is not stopped or partially stopped
• Tongue position: is necessary for sound production,
• /r/ Front Airflow: air escapes over front of tongue
• /l/ later airflow: air escapes over sides of tongue

Glides (/w/ and "y"): 

• Sonorant sound: sound is not stopped or partially stopped
• Semivowel: almost a vowel but starts a syllable instead of being in the middle of it
• Produced with less precise tongue placement and minimal constriction

Because liquids require more refined oral motor control and phonological organization, they are more likely to be simplified during speech development.

Is Gliding a Normal Part of Development?

Yes. Gliding is considered a typical developmental process in young children.

According to  ASHA,, gliding is usually suppressed by approximately 5 years of age. If gliding persists beyond this age, a speech-language evaluation and intervention are recommended.

How Is Gliding Treated in Speech Therapy?

Gliding is treated as a phonological pattern, not as an isolated articulation error. Intervention focuses on helping the child understand and produce meaningful sound contrasts rather than simply practicing one sound in isolation.

There are several evidence-based approaches for treating phonological disorders. For an overview, see the Phonological Disorders or Contrastive Approaches pages.

Below are key components commonly used when treating gliding.

Minimal Pairs

Minimal pairs are a foundational tool when treating gliding.

Minimal pairs:

• Consist of two words that differ by one phoneme
• Directly confront the child’s error pattern
• Support both sound perception and production awareness

Common minimal pair contrasts for gliding include:

• /r/ vs /w/
• /l/ vs /w/
• /l/ vs /j/

These contrasts help children hear, feel, and understand the difference between their error sound and the target liquid.

Phonological Awareness

Phonological awareness plays an important role in phonological intervention.

For children who glide, therapy often includes activities that strengthen the child’s ability to:

• Identify liquid and glide sounds
• Discriminate between error and target sounds
• Recognize sounds in initial and final word positions

Supporting awareness of both the error sounds (/w/, /j/) and the target sounds (/r/, /l/) can significantly improve treatment outcomes.

Sentence-Level and Generalization Practice

As accuracy improves, children must practice using both the error sound and the target sound within connected speech.

Sentence-level activities that include both sounds:

• Increase linguistic demand
• Promote generalization
• Better reflect real-life communication demands

This step is essential for moving beyond structured practice and into functional speech.
