What is Dysarthria?

Dysarthria is a motor speech disorder caused by changes in the muscles and movements used for speech. It can occur when the speech system is affected by weakness, reduced coordination, altered muscle tone, or reduced range/speed of movement.

Dysarthria can affect:

• Speech clarity (intelligibility)

• Rate and rhythm

• Voice quality and loudness

• Breath support for speech

• Resonance (how “nasal” speech sounds)

Dysarthria commonly occurs after neurological conditions such as stroke, traumatic brain injury (TBI), Parkinson’s disease, multiple sclerosis (MS), cerebral palsy, and motor neurone disease (ALS/MND).

At Palms Physiotherapy & Allied Health, our speech pathologists provide assessment and therapy for children and adults with dysarthria, focusing on clearer communication and practical strategies for everyday life.

Signs and Symptoms of Dysarthria

Symptoms vary depending on the underlying cause and which parts of the speech system are affected. Common signs may include:

• Slurred or imprecise speech

• Speech that is too slow, too fast, or difficult to regulate

• Reduced loudness or a voice that sounds weak, strained, hoarse, or breathy

• Monotone speech or reduced pitch variation (“flat” sounding speech)

• Uneven rhythm or “scanning” speech

• Difficulty coordinating movements of the lips, tongue, jaw, or soft palate for speech

• Reduced breath support for longer sentences (running out of breath while talking)

• Resonance changes (speech may sound more nasal in some presentations)

Some people with dysarthria know exactly what they want to say but find it difficult to say it clearly due to motor speech changes. Swallowing or secretion management difficulties can also co-occur for some conditions and may require additional assessment.

What Causes Dysarthria?

Dysarthria occurs due to nervous system changes that affect speech movement control. Causes may include:

• Stroke

• Traumatic brain injury (TBI)

• Parkinson’s disease and other movement disorders

• Multiple sclerosis (MS)

• Cerebral palsy

• Muscular dystrophy

• Motor neurone disease / ALS

• Brain tumours or other neurological conditions

Understanding the cause and pattern of dysarthria helps guide therapy and recommendations.

How Speech Pathology Helps Dysarthria

Treatment is individualised and based on assessment findings, goals, and everyday communication needs. Therapy commonly focuses on functional speech tasks and evidence-based strategies such as:

• Intelligibility strategies: clear speech/over-articulation techniques, slower rate, and phrasing to improve understandability
  
  

• Rate control: strategies to regulate speech speed and improve rhythm (e.g., pausing, pacing techniques)

• Breath support for speech: improving coordination of breathing and speech to support loudness and sentence length

• Voice strategies (when indicated): techniques to support efficient voice production, reduce strain, and improve audibility

• Communication repair strategies: repeating key words, rephrasing, checking listener understanding, and using context cues

• Environmental modifications: reducing background noise, positioning, and listener strategies

• AAC support (when helpful): low-tech or high-tech communication supports to maintain participation—especially for severe dysarthria or progressive conditions
  
  

Where appropriate, we also provide education for family members and communication partners to improve success in everyday interactions.

Types of Dysarthria

Different neurological pathways can produce different speech patterns. Common dysarthria types include:

• Spastic dysarthria: often sounds strained, slow, and effortful

• Flaccid dysarthria: may involve breathy voice, hypernasality, and weakness-related changes

• Ataxic dysarthria: often includes irregular rhythm and imprecise articulation

• Hypokinetic dysarthria: common in Parkinson’s; may involve reduced loudness and rapid/blurred speech

• Hyperkinetic dysarthria: can involve variable loudness/rate due to involuntary movements

• Mixed dysarthria: features of more than one type (common in conditions such as MND/ALS)

A speech pathology assessment helps identify the features most relevant to therapy planning.

Why Early Support Matters

Early assessment and support can help people:

• Improve clarity and reduce communication breakdowns

• Learn practical strategies for home, school, work, and community settings

• Build confidence and reduce frustration

• Plan supports over time (especially for progressive neurological conditions)
  
  

Dysarthria Therapy for Children and Adults

Children
Dysarthria in children may occur with conditions such as cerebral palsy or genetic/neurological presentations. Therapy often focuses on:

• Speech clarity and intelligibility strategies

• Breath/voice support for functional speech

• Participation at school and in social environments

• Communication supports as needed
  
  

Adults
Adults may develop dysarthria after stroke, TBI, or with progressive neurological conditions. Therapy may focus on:

• Clear speech strategies and rate control

• Voice and breath support (where appropriate)

• Practical communication strategies for work and daily life

• AAC supports if speech becomes significantly impaired
  
  

Access Dysarthria Support in Malaga

If you’re seeking dysarthria assessment and therapy in Malaga, our speech pathology team can help with practical, evidence-based strategies to improve communication and support everyday participation.

Speech Therapy Services in Perth for Children & Adults

Speech Therapy (also called Speech Pathology) focuses on assessing, diagnosing, and treating communication and swallowing difficulties. At Palms Physiotherapy & Allied Health, our speech pathologists support children, teens, and adults to improve speech clarity, language skills, social communication, voice and fluency and swallowing safety.

How Can Speech Therapy Help You?

Speech therapy can help with a wide range of concerns, including:

• Speech delays in children: Supporting speech sound development, clarity, and age-appropriate communication.

• Speech sound disorders: Including articulation (sound production) and phonological (sound patterns) difficulties.

•  Language disorders: Helping with both receptive language (understanding) and expressive language (using words and sentences).

• Swallowing and feeding difficulties (dysphagia): Supporting people who have difficulty swallowing safely due to conditions such as stroke, traumatic brain injury, or neurological conditions.

• Social communication differences: Supporting conversational skills, turn-taking, perspective-taking, and understanding non-verbal communication.

•  Stuttering and fluency disorders: Helping clients manage fluency, reduce effort/tension, and build confidence in communication.

Speech Therapy Services We Provide

Paediatric Speech Therapy

• Paediatric speech therapy supports children with speech, language, communication, and early literacy needs using evidence-based and child-friendly approaches. Sessions may be play-based (especially for younger children), while still being structured and goal-directed.

• Common areas we support include:

  1. Speech sound development (clarity and intelligibility)

  2. Language delays and developmental language disorder
