Communicating with ALS: Augmentative and Alternative Communication

Communication can become harder for a person living with amyotrophic lateral sclerosis (ALS), particularly when the muscles used for speech, breathing, typing or handwriting are affected. Changes may develop gradually or quickly, and each person’s pattern is different. A clear voice in the morning may become quieter later in the day, while fatigue, respiratory weakness or changes in facial movement can make conversation more demanding.

Augmentative and alternative communication (AAC) includes every method that supports or replaces spoken communication. It may involve a louder speaking technique, spelling with a letter board, pointing to written words, using eye movements, or operating a speech-generating device. AAC is not a last resort. Introducing suitable options early can preserve independence and reduce the pressure to communicate quickly.

For families in Australia, communication support may involve a general practitioner, neurologist, speech pathologist, occupational therapist, respiratory team and disability service. Access can differ between metropolitan Melbourne, Sydney, Brisbane or Perth and rural or remote communities. Planning ahead helps a person communicate at home, in hospital, at work, in shops and during urgent healthcare conversations.

How ALS can change communication

Motor neurone disease, including ALS, can affect the muscles responsible for speech. Weakness in the lips, tongue, palate and throat may produce dysarthria, where speech sounds slurred, quiet, nasal or unusually slow. A person may know exactly what they want to say while finding it difficult to make others understand. This gap between language and speech ability can be frustrating and emotionally exhausting.

Breathing changes can reduce the amount of air available for speaking. A person might manage short phrases but lose volume during a longer conversation, after walking, or late in the day. Dry mouth, saliva problems, coughing and fatigue can also interfere. Some people develop pseudobulbar affect, causing involuntary laughing or crying that does not match how they feel; this can complicate social situations without reflecting their intentions.

Communication can be affected even when speech remains understandable. Hand weakness may make writing, texting or using a standard keyboard slow and painful. Reduced neck or arm control may limit access to a phone or tablet. In a smaller group of people, cognitive or behavioural changes associated with frontotemporal involvement affect word retrieval, attention, judgement or the ability to organise a message. These changes call for flexible communication strategies rather than assumptions about a person’s understanding.

A useful early step is recording how the person communicates on a good day and a tiring day. Note speech rate, volume, typical listeners, languages used at home and any physical movement that remains reliable. The guide for Toyama residents also illustrates why practical information and local support networks matter when families are learning about ALS and planning care.

Building an individual communication system

A speech pathologist with experience in AAC can assess current abilities and likely changes over time. The assessment should consider speech, language, vision, hearing, breathing, posture, hand and finger movement, eye control, literacy and fatigue. It should include the person’s priorities: talking with a partner, joining family meals, managing a business, ordering coffee, communicating with children or speaking privately with a doctor.

AAC is commonly divided into unaided and aided methods. Unaided communication uses the body, such as facial expression, gestures, eye pointing, head movement or agreed signals. Aided communication uses an external item. Low-tech options include alphabet boards, topic boards, notebooks, printed photographs and cards showing “yes”, “no”, “pain”, “toilet”, “tired” or “I need more time”.

High-tech AAC may use a tablet or dedicated speech-generating device with text-to-speech. The person types or selects letters, words, phrases and symbols, and the device produces a voice. Access can be through touch, a stylus, adapted switches, head tracking or eye gaze. Some systems allow message banking, in which a person records commonly used phrases or a synthetic voice before speech changes significantly. A familiar voice can carry personal meaning, especially in family conversations.

The most effective setup may combine several methods. A person might use natural speech for short exchanges, a stored message for frequent needs, an alphabet board when tired and eye gaze when hand movement declines. A communication passport can explain the person’s reliable yes/no signal, best access method, communication rate, preferred name, languages and how others should respond. It is valuable for support workers, hospitals, schools, workplaces and new clinicians.

Making conversations easier and more respectful

Communication partners have an important role. Face the person, reduce background noise and allow enough time for a response. Speak normally rather than raising your voice, unless hearing loss is present. Ask one question at a time and offer a clear yes/no format when open-ended questions are tiring. Confirm the message without pretending to understand: “I heard you say the first part. Did you mean medication or transport?”

Never assume that unclear speech means unclear thinking. Avoid finishing every sentence, speaking to a companion instead of the person, or answering before the message is complete. If the person uses AAC, look at them while they compose the message. Do not treat the device as a barrier or talk about the person as if they were absent. A short pause is often more respectful than repeated demands to hurry.

Australian daily life creates many practical communication situations. A person may need to tell a barista in Adelaide about a modified drink, communicate with a bus driver in Brisbane, speak to staff at a Melbourne hospital, or manage a phone call with a service provider in Perth. Noise at a shopping centre, a crowded football ground or a family barbecue can make speech recognition harder. A printed card, phone-based text, or pre-programmed phrase such as “Please give me time to use my device” can make these settings more manageable.

At home, agree on a repair strategy for misunderstandings. The listener might repeat the part they understood, identify a topic category, or invite spelling of the first letter. A partner can keep the communication device charged and positioned correctly without taking control of it. Privacy matters too: personal messages, medical decisions and financial information should be communicated in a way that allows the person to speak for themselves.

Choosing technology and funding in Australia

The Australian AAC market includes dedicated communication devices, eye-gaze systems, switch-access equipment, mounting arms, alternative keyboards and communication apps for tablets. Consumer tablets can be useful for early or occasional support, but they may lack robust mounting, accessible charging, custom access methods or reliable technical assistance. A dedicated device can be more suitable when communication is essential throughout the day, particularly if it must work with limited movement or while the person is lying down.

A trial is more informative than a product brochure. The person should test the system in different positions, lighting conditions and levels of fatigue. Consider screen glare, Australian English voices, volume, battery life, portability, repair arrangements, warranty, software updates and whether the device can be used outdoors. Eye-gaze systems may be affected by glasses, sunlight, eyelid control or changes in posture, so a backup method remains important.

For eligible Australians under 65, the National Disability Insurance Scheme (NDIS) may fund communication equipment and related supports when they meet reasonable and necessary criteria. A speech pathologist or occupational therapist can provide evidence about functional communication needs, safety, participation and the expected impact of the equipment. Funding pathways and service availability vary, and people should check current NDIS guidance rather than assume that every app or device will be covered.

People over 65 may need to explore My Aged Care, state or territory equipment programs, hospital services, private health insurance or community organisations. Medicare can support some allied-health appointments through relevant care plans, although this does not automatically cover a complete AAC assessment or device. In rural Queensland, Western Australia, New South Wales and other large regions, telehealth can extend specialist advice, while local therapists may be essential for hands-on setup and follow-up.

Australian privacy and disability rights also shape communication support. The Disability Discrimination Act 1992 protects equal access and participation, while health services must make reasonable efforts to communicate with patients who have disability. A person can request extra time, written information, an interpreter or access to their AAC system during appointments. Hospitals and emergency services should be told how the person communicates and how to identify consent, discomfort and urgent needs.

Preparing for changing needs

AAC planning should begin before speech becomes extremely difficult. A person may still speak clearly enough to make important recordings, select vocabulary and explain preferred pronunciation. Message banking can include names, jokes, greetings, stories, work phrases and expressions used with family. Voice banking is not suitable or affordable for everyone, and a synthetic voice or text display can be equally valuable.

Create a communication emergency plan. It might state the person’s reliable yes/no response, how they indicate pain or breathlessness, how to access their device, and what to do if the battery fails. Keep a low-tech alphabet board and key phrase card in the home, car and usual bag. A printed copy can be useful during a power outage, hospital transfer or technical fault. The plan should be updated when movement, vision, breathing or cognition changes.

Swallowing and respiratory care should be considered alongside communication. A person who is short of breath may not have enough energy for lengthy speech, and meals may require close attention to fatigue and aspiration risk. Healthcare staff should avoid treating communication as optional during clinical decisions. The person must have a dependable way to report pain, consent, distress, medication concerns and changes in symptoms.

Support workers and family members benefit from practising before a crisis occurs. They can learn how to position a tablet, clean an eye-gaze camera, interpret the person’s signals and charge equipment safely. Staff changes are common in disability services, so written instructions prevent knowledge from disappearing when a familiar worker leaves. Training should include dignity, privacy and the person’s right to reject a proposed device or communication method.

Supporting connection, identity and choice

Communication is more than transmitting basic needs. It allows a person to tell stories, maintain friendships, express humour, make decisions, work, parent, participate in culture and remain involved in the community. AAC should therefore include vocabulary that reflects the person’s identity, relationships, interests and languages. A system filled only with medical terms may be technically functional while failing to support a satisfying life.

Families can protect social connection by adapting the pace and setting of conversations. Short visits, quieter rooms and planned breaks may be easier than large gatherings. In Australia, video calls can help when distance separates families, but the platform should be tested with the person’s access method. Text, email or recorded messages may be preferable when live conversation is tiring. Communication partners should include the person directly in group discussions rather than summarising everything for them.

When a loved one is newly diagnosed, practical guidance about daily support can help families avoid common communication pressures; supporting a loved one with ALS offers a related perspective on the value of patience, coordination and respect. Local ALS and motor neurone disease organisations, multidisciplinary clinics, speech pathology practices and peer networks can add experience that a single appointment cannot provide.

The person living with ALS remains the central decision-maker wherever possible. Their preferred voice, access method, conversation pace and level of assistance should guide the plan. AAC may change as the condition changes, but the goal remains steady: enabling the person to communicate safely, efficiently and on their own terms in every setting that matters to them.
