Functional Voice Disorders and Functional Neurological Disorder (FND) in Perth

Understanding Functional Voice and Speech Symptoms

Some people experience significant voice or speech changes even when there is no structural damage to the vocal folds or no neurological disease that explains the symptoms in the usual way. These presentations are often described as functional voice disorders and, in some cases, may occur as part of Functional Neurological Disorder (FND) (previously called “conversion disorder”).

These symptoms are real, involuntary, and treatable, and they can have a major impact on communication, confidence, work, and social participation.

At Palms Physiotherapy & Allied Health, our speech pathologists provide assessment and therapy for functional voice and communication presentations, and we work alongside medical and mental health providers when needed.

What is a Functional Voice Disorder?

A functional voice disorder involves difficulty producing a normal voice due to changes in how the voice system is being used (coordination, tension, breathing/voicing patterns), rather than a problem such as a vocal fold lesion or paralysis.

Functional voice presentations can include:

• Aphonia (loss of voice/whispered voice)

• Dysphonia (hoarse, breathy, strained, or weak voice)

• Intermittent voice loss or variable voice quality

• Voice symptoms that may fluctuate with fatigue, stress, or high voice demand

What is Functional Neurological Disorder (FND)?

FND is a condition where people experience neurological symptoms (e.g., movement, sensory, speech/voice symptoms) due to differences in nervous system functioning rather than structural neurological disease. Diagnosis is typically based on positive clinical features identified by trained clinicians.

Speech/voice symptoms in FND can include:

• Functional dysphonia or aphonia

• Changes in speech clarity or fluency

• Variable speech/voice control (often inconsistent across tasks)

Important: Rule Out Medical Causes First

Because hoarseness or voice loss can have multiple causes, it’s important that appropriate medical assessment occurs where indicated. Depending on symptoms, this may include:

• ENT/laryngology assessment (to visualise the vocal folds/voice box)

• GP review (and/or neurology review if neurological symptoms are present)

Speech pathology works best when we understand what has been ruled out and what has been identified clinically.

How Speech Pathology Can Help

Speech pathology focuses on restoring efficient, comfortable voice production and improving functional communication. Therapy is tailored to the individual and may include:

Voice Re-Establishment and Rehabilitation

• Techniques to help bring voice back safely (for aphonia/near-aphonia presentations)

• Reducing unhelpful tension patterns and improving coordination between breathing and voicing

• Gradual rebuild of voice endurance and reliability

Breathing and Laryngeal Tension Strategies

• Breath support and airflow management for easier voicing

• Strategies to reduce throat/neck tension that can contribute to strain

Symptom Management and Self-Monitoring

• Understanding triggers and early warning signs (fatigue, vocal load, stress)

• Practical pacing and voice-use strategies for work and daily life

Communication Confidence and Participation

• Strategies to support communication in high-demand settings (meetings, phone calls, noisy environments)

• Planning for graded return to voice demands

Coordinated Care and Referrals (When Needed)

Functional voice and FND presentations often benefit from a coordinated approach. With your consent, we can liaise with and/or recommend referral to:

• ENT/laryngology and medical teams

• Psychology/mental health providers (when support with stress, trauma, anxiety, or adjustment is needed)

• Other allied health professionals involved in your care

Speech pathology does not replace mental health care, but it can be an important part of a broader support plan.

Why Early Support Matters

Early assessment and the right therapy approach can help:

• Reduce the risk of entrenched voice patterns

• Improve confidence and participation sooner

• Provide practical strategies to manage symptoms and voice demands

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

  3. Social communication support

  4. AAC (Augmentative and Alternative Communication) where appropriate

  5. Early literacy foundations (e.g., phonological awareness)

Adult Speech Therapy

• Adult speech therapy supports adults with communication and swallowing needs related to neurological conditions, injury, medical events, or age-related changes. Therapy is practical, functional, and designed around everyday participation (home, work, community).

• Common areas we support include:

  1. Communication changes after stroke, traumatic brain injury (TBI), or neurological illness

  2. Dysarthria and motor speech changes

  3. Cognitive-communication difficulties (attention, memory, organisation impacting communication)

  4. Voice therapy where indicated

  5. Dysphagia support and mealtime strategies

NDIS Speech Therapy Services

• NDIS speech therapy is available for self-managed and plan-managed participants. Therapy may focus on functional communication goals, speech clarity, social interaction and participation, and AAC support where required. We collaborate with participants, families, support coordinators, schools, and relevant providers to support practical, meaningful outcomes.

Speech Therapy for Swallowing Disorders (Dysphagia)

• Dysphagia (swallowing) support helps when swallowing difficulties affect hydration, nutrition, safety and confidence with eating and drinking. Our speech pathologists can complete clinical assessments (as appropriate), provide strategies for safer swallowing, recommend targeted exercises when indicated, and support shared-care referral pathways with GPs/ENT/medical teams when needed.

Speech Therapy – What We Can Help With

Speech pathologists (speech therapists) support children and adults with a wide range of speech, language, voice, fluency, and swallowing needs. Below is a practical overview of the common areas we assess and treat at Palms.

Speech Sound & Motor Speech

• Articulation Disorders: Difficulty producing specific speech sounds clearly (e.g., /s/, /r/, /l/).

• Phonological Disorders: Patterns/rules of sound errors that reduce intelligibility (e.g., fronting, final consonant deletion).

• Apraxia of Speech: Motor planning/programming difficulty; speech errors may be inconsistent and speech can sound “choppy.”

• Dysarthria: Speech changes due to weakness, tone or coordination differences affecting speech muscles.

Language

• Expressive Language Disorder: Difficulty using words/sentences to share ideas, tell stories, ask questions, or use grammar accurately.

• Receptive Language Disorder: Difficulty understanding spoken/written language, following instructions, or processing complex language.

• Mixed Expressive–Receptive Language Disorder: Difficulties with both understanding and expressing language.

• Developmental Delays: Support when speech and language milestones are developing more slowly than expected.

• Aphasia: Language difficulty often after stroke/brain injury, affecting speaking, understanding, reading and/or writing.

Voice

• Hoarseness or Strained Voice: Raspy, breathy, strained or unreliable voice; can relate to vocal load, inflammation, reflux, or vocal fold changes.

• Vocal Cord Paralysis: One or both vocal folds do not move normally, impacting voice, breathing and/or swallowing.

• Resonance Disorders: Speech that sounds overly nasal or “blocked”; may be structural, neuromuscular and/or learned.

• Gender Affirming Voice and Speech Therapy: Support to align voice and communication with gender identity using safe, evidence-based voice techniques.

• Psychogenic Voice Disorders and Conversion Disorder: Voice changes linked to psychological factors; therapy supports voice recovery and functional communication.

Fluency

• Stuttering: Disruptions to speech flow (repetitions, prolongations, blocks) that can impact confidence and participation.

• Cluttering: Fast or irregular speech rate that can reduce clarity and organisation of spoken messages.

Social Communication

•  Pragmatic Language Disorder: Support for conversation skills, turn-taking, topic maintenance, inference, and interpreting non-verbal cues.

Swallowing & Feeding

• Dysphagia (Swallowing Disorders): Assessment and strategies to support safe swallowing and reduce aspiration risk (often alongside GP/ENT/medical teams when needed).

Hearing & Listening

• Hearing Impairments: Therapy to support listening, speech clarity, language development, and communication strategies in partnership with audiology where required.

Neurological Conditions

• Speech Therapy for Neurological Conditions: Communication and swallowing rehabilitation for stroke, TBI, Parkinson’s disease, MS, dementia and other neurological conditions.

Early Literacy & Phonological Awareness

• Phonological Awareness: Therapy targeting sound awareness skills that underpin reading/spelling (rhyming, blending, segmenting, manipulation).

Post-Surgical Head & Neck Rehab

• Post‑Surgical Rehabilitation for Laryngectomy and Head and Neck Cancer: Multidisciplinary support for communication, swallowing and function after surgery/treatment (in shared care with your treating team).
