For many parents seeking support for a child who is struggling to speak clearly, various techniques may be suggested or discussed. Among these are activities like blowing bubbles, licking peanut butter off lips, wiggling the tongue, or blowing through whistles. These are commonly referred to as Non-Speech Oral Motor Exercises (NSOMEs) or nonspeech oral motor treatments.
It is natural to assume that if a child struggles to produce clear speech, "strengthening" the mouth muscles must be the solution. However, current clinical research and professional guidance do not establish that nonspeech oral motor exercises reliably improve speech sound production in children with developmental speech sound disorders, and they are not necessary for every child with a speech delay.
Direct Answer
No. Not every child with a speech delay needs oral motor exercises. Whether they are appropriate depends on the child's specific speech, oral-motor, feeding, structural, or neurological needs.
Speech delay is a broad term, and the appropriate therapy depends on whether a child has a speech sound disorder, language difficulty, motor speech disorder, or another underlying communication need.
Understanding how speech sounds are actually produced helps clarify when oral motor activities might play a role and when direct speech therapy is required instead.
What are Non-Speech Oral Motor Exercises?
Non-Speech Oral Motor Exercises refer to activities aimed at moving, stretching, or building strength in the lips, tongue, jaw, or cheeks without simultaneously producing speech sounds. These activities focus on physical movement rather than communication.

Speech Production vs. Muscle Strength
A common misconception is that speech sound errors are caused by weak mouth muscles. In reality, speech production depends primarily on precise, coordinated movements of the lips, tongue, jaw, and other speech structures rather than simply increasing muscle strength.
- Muscle Force vs. Fine Control: Activities like chewing or biting down require greater physical force. However, speaking relies on delicate, rapid control rather than maximum muscle effort.
- Motor Control and Coordination: Clear speech requires the brain to coordinate complex movements of the tongue, lips, and jaw in millisecond sequences to form specific speech sounds.
Because nonspeech oral movements do not directly practice the precise movements required for speech, improvement in a nonspeech task does not necessarily transfer to clearer speech.
What the Clinical Evidence Says
Major professional organizations, including the American Speech-Language-Hearing Association (ASHA), have examined systematic reviews and research regarding non-speech oral motor exercises.
Current evidence suggests:
- Limited Evidence of Speech Benefit: Research has not established that nonspeech oral motor exercises reliably improve speech sound production or intelligibility in children with developmental speech sound disorders. A Cochrane review found insufficient evidence to determine whether non-speech oral motor treatments improve speech sound production in children with developmental speech sound disorders.
- Specific Needs for Specific Skills: Speech is a highly specific motor skill, so practicing speech movements and sounds directly is generally more relevant to speech outcomes than practicing unrelated nonspeech movements.
- Targeting the True Underlying Issue: For many children with speech sound disorders, difficulties may involve speech-sound learning, phonological patterns, or speech motor planning rather than reduced oral muscle strength.
When Might Oral Motor Assessment Be Relevant?
While non-speech exercises are not a universal treatment for general speech delays, oral structural and functional evaluations remain an important part of a clinical assessment.
An evaluation of the mouth structures (oral mechanism exam) helps speech-language pathologists determine if physical or motor factors are impacting communication or feeding. However, these findings must be interpreted carefully within the child's overall profile.
Oral motor or structural factors may be clinically relevant in specific conditions, such as:
| Clinical Area | Observation | Standard Clinical Focus |
|---|---|---|
| Feeding & Swallowing Difficulties | Difficulty chewing, managing saliva, or swallowing safely. | Targeted feeding therapy focusing directly on safe eating and drinking mechanics. |
| Motor Speech Disorders (e.g., Dysarthria) | Muscle weakness or altered muscle tone due to neurological conditions. | Task-specific motor practice combining breath support, resonance, and speech production. |
| Structural Differences | Anatomical variations such as a cleft palate or other oral structural variations. | Structural assessment and referral to appropriate medical specialists alongside speech therapy. |
For children with typical oral anatomy and standard muscle tone who present with speech delays or articulation errors, therapy focuses directly on speech sound production rather than non-speech muscle exercises.
Evidence-Based Approaches to Supporting Speech Delays
When supporting a child with a speech sound delay or phonological disorder, evidence-informed interventions prioritize direct, functional communication:
1. Comprehensive Speech-Language Assessment: Determining the Root Cause of Speech Differences
A comprehensive assessment considers the child's speech sound production, phonological patterns, language skills, oral structures and functions, and other relevant factors to understand the nature of the communication difficulty.
2. Direct Speech Sound Intervention
Therapy focuses on modeling, practicing, and refining target speech sounds directly in syllables, words, phrases, and natural conversation.
3. Auditory Discrimination Training
Children are guided to hear the distinction between speech sounds, helping them recognize and self-correct their own speech errors.
4. Functional and Play-Based Integration
Speech practice is woven into everyday play, routines, and child-led interactions to ensure new sounds carry over into real-world settings.
Moving Forward Safely
Not every child with a speech delay needs oral motor exercises. Because speech clarity depends on precise speech-motor coordination and accurate learning of speech sounds rather than simply increasing oral muscle strength, effective therapy focuses on the child's specific speech and communication needs.
