AAC for CHARGE Syndrome: Planning Guide
AAC for CHARGE syndrome starts with the person, not a device list. CHARGE affects people in very different combinations of vision, hearing, balance, breathing, heart health, and energy. A speech-generating device that helps one person can be unusable for another. This guide is for families and speech-language pathologists (SLPs) who want a practical way to plan augmentative and alternative communication (AAC) without treating CHARGE as one profile.
Nothing here diagnoses CHARGE, chooses a device, or predicts how someone will communicate. An SLP, audiologist, teacher of the visually impaired, and the people who know the communicator best should shape the plan together.
What AAC for CHARGE syndrome has to account for
CHARGE is a pattern of congenital differences, not a single communication diagnosis. The letters point to coloboma of the eye, heart differences, choanal atresia, growth or developmental differences, genital or urinary differences, and ear differences that can include hearing loss and vestibular (balance) disorders. Many people do not have every feature. The CHARGE Syndrome Foundation's parent manual and clinical summaries both stress that the mix, and the severity of each feature, is individual.
That mix is why a generic AAC recommendation fails. Coloboma and other eye differences can shrink the useful visual field or reduce detail. Hearing can range from typical hearing to severe or profound loss, and there is no single typical audiogram. About half of people with CHARGE have severe to profound hearing loss, while others have milder sensorineural or conductive loss. Some also have combined vision and hearing loss. CHARGE is a leading cause of congenital deafblindness, which means many communicators miss information that sighted, hearing peers pick up by watching and overhearing.
Balance and fatigue matter as much as eyes and ears. Missing or incomplete semicircular canals are common and can make posture, head control, and walking harder. Coordinating looking, listening, and reaching at the same time can be exhausting. A slow reply is not a refusal. Pennsylvania's Office of Developmental Programs notes that a delayed response often means the person is still processing, and that familiar partners and familiar places make communication easier.
Medical load shapes the day too. Heart differences, airway or choanal concerns, feeding, and hospital stays can interrupt practice. A plan that only works in a quiet therapy room will not survive a noisy classroom, a clinic visit, or a week of poor sleep. Write the plan for the week the person actually has.
Start with sensory access, not a symbol set
Before anyone picks a vocabulary page, find out which senses carry information on a good day and on a tired day. Ask the family, the teacher of the visually impaired, and the audiologist what the person already uses: residual vision, residual hearing, touch, objects, or a mix. Then watch. Does the person turn to a voice, a light, a tap on the arm, or an object placed in the hand?
A few checks keep trials honest:
- Vision.
Note field cuts, light sensitivity, preferred viewing distance, and whether high contrast helps. Large symbols on a bright screen can still disappear if they sit outside the useful field or wash out in glare.
- Hearing.
Confirm hearing-aid or cochlear-implant use, which ear is stronger, and whether speech, environmental sounds, or device voice output are actually heard in the rooms where the person spends time.
- Touch and movement.
Some people need an object or a touch cue before a symbol makes sense. Hand-under-hand support, offered rather than grabbing the person's hand, lets them explore a key or object and pull away.
- Together.
Many people cannot listen, look, and reach in the same moment. Offer one channel, wait, then add another.
The alternative access methods page is a catalog of touch, switch, head-mouse, and eye-gaze options. It is a menu, not a ranking. For CHARGE, eye gaze is only worth a trial when useful vision and a stable head position are both present. A switch or a partner-assisted scan can be a better first trial when vision is limited or fatigue is high. Direct touch with a keyguard can work when the person can isolate a finger and see or feel the target. None of these is the "CHARGE method.
Forbes AAC's access-feature matching article walks through how SLPs compare selection methods in general. Use that process, then add the CHARGE-specific questions in the table below. Do not import a checklist written for a different diagnosis.
Questions to settle before a device trial
A short trial beats a long debate. The goal of the first sessions is to learn which setup the person can use more than once, with a partner who is not guessing. Record what you changed and what the person did, including "no response yet."
Question | Why it matters for CHARGE | What to watch in a trial |
What gets the person's attention? | Name, touch, object, or light cues work differently when vision and hearing are both reduced. | Agree on one cue and use it every time before you offer a message. |
How long is a fair wait? | Processing can be slow, especially when senses compete or the person is tired. | Time the pause. Do not fill it with a second prompt. |
Which display can they use? | Field loss, contrast needs, and symbol size change what fits on a screen. | Compare a few large, high-contrast targets with a denser grid. Stop if the person only hits the edge. |
Where does the device sit? | Balance and posture limits can make a lap device or a poorly placed mount unusable. | Check viewing angle, reach, and whether the mount stays put during a position change. |
What does voice output add? | Partners may hear the device when the communicator does not, or the voice may be one more noise. | Try speech on and off. Ask whether the person startles, ignores it, or orients to it. |
When does fatigue show up? | Sensory coordination is hard work. A good first minute can collapse by minute ten. | Note the minute attention drops. Plan shorter turns and a sensory break. |
Display layout is part of access. CoreWord offers smaller grids (6, 12, and 20) as well as larger ones, including high-contrast versions of the smaller sets. A smaller grid is not a judgment about intelligence. It is often the only layout that fits a restricted visual field. Real objects and photos with plain backgrounds can bridge to symbols when abstract icons are not yet meaningful. Keep one concrete set for routines the person already knows, such as choosing a snack, a song, or a place to go.
Mounting and sound are practical, not cosmetic. A device parked at the wrong height is invisible to someone who must hold their head a certain way. APEX mounts cover table, floor, and wheelchair setups, and the first applicable wheelchair-mount home visit can be arranged at no charge. Later visits may cost extra. A wearable speaker such as SoundPOD can move the device voice closer to the listener, which helps in a group, but it does not fix a hearing loss. Confirm with the audiologist whether the person hears that speaker.
Build the partner routine before you add words
People with CHARGE often depend on partners who respond in a way that matches their sensory needs. The Pennsylvania communication brief puts the responsibility on the listener: notice the attempt, accept it, and answer it. If partners wait for a perfect button press, they will miss the lean, the reach, the vocalization, and the body shift that already mean something.
A usable routine is short and repeatable:
Get attention with the agreed cue, then pause.
Offer one real choice tied to something happening now.
Wait the agreed number of seconds. Count silently.
Respond to any clear attempt, including a reach or a look, and say what you think it meant.
Do the thing. A message that changes nothing teaches the person to stop trying.
Stop while the person is still willing. Fatigue is data, not a behavior problem.
Visual schedules, object cues, and a quieter corner help receptive communication, which is how the person takes information in. Expressive AAC, the system they use to say something, will stall if nobody has made the day predictable first. Reduce background noise and visual clutter during practice. Familiar rooms and familiar people are fairer tests than a new clinic on a hard medical week.
Partner coaching is its own skill. Forbes AAC's partner-education article covers how to teach the people around an AAC user without taking over their turns. For CHARGE, add two rules: one person talks at a time, and nobody touches the communicator's hands unless they have invited that help. Hand-under-hand is an offer. It is not hand-over-hand control.
In school, combined vision and hearing loss is often supported by a teacher of the visually impaired, a teacher of the deaf, an intervener, or an occupational therapist. An intervener's job, when a team decides one is needed, is to provide access to information the student cannot gather by watching and overhearing, and to keep communication moving with other people. AAC does not replace that person. The device and the partner have to agree on the same cues.
How an SLP can trial equipment
Forbes AAC does not ship a device because a diagnosis is CHARGE. Trials are individualized, and the path depends on who is asking.
A licensed SLP can borrow equipment for evaluation, including speech-generating devices and access tools such as switches or eye gaze. The standard clinician loan is up to four weeks, the device stays with the SLP, and it is subject to availability. A home trial is different. The user's SLP starts it only after an insurance benefits check. The 24- to 48-hour timing for the next-step code begins after coverage is confirmed, not when a family first calls. Families should not try to open a home trial on their own.
SLPs who already have an iPad can ask about the evaluation kit, a no-cost loan of a SoundPOD, a FlexABLE handle, and a limited keyguard for eligible clinicians or facilities. The kit is not a free speech-generating device and it is not something the family keeps.
During the loan, test one change at a time. If you change grid size, viewing distance, and access method in the same session, you will not know which change helped. Bring the notes to the audiologist and the vision teacher before the loan ends. A dedicated funded device, if a payer later approves one, may restrict non-covered features such as open web browsing. Do not promise that every app, text message, or email tool will be on a funded device. Schools, VA programs, and other direct-pay buyers get a quote through sales rather than a public checkout. Forbes does not publish device prices, and coverage is never guaranteed.
CoughDrop can be useful when boards need to follow a person across a tablet at school and a dedicated device at home, because boards sync through the cloud and can work offline after syncing. That is a workflow convenience. It is not a statement that one app fits CHARGE better than another. Confirm the app, the grid, and the keyguard against the actual device before anyone orders.
What this plan is not
AAC does not treat CHARGE, raise a test score, or replace hearing technology, vision services, or medical care. A person may use a device for some messages and objects, gestures, or signs for others. Symbolic language, whether signs, photos, or abstract symbols, can take a long time, and some people rely on partners to interpret body language for years. That is still communication.
Avoid three traps:
- One device for the diagnosis.
Two people with CHARGE can need opposite setups. One may use a dense, voice-output grid. Another may need three objects and a partner who waits.
- Ranking access from "highest" to "lowest."
Eye gaze is not more advanced than a switch. The better method is the one the person can repeat without pain or exhaustion.
- Treating a slow response as noncompliance.
Add time and reduce sensory load before you add prompts.
If behavior is intense, assume overload, pain, or a missed message before you assume refusal. Medical teams already watch heart, airway, feeding, and balance. Fold communication notes into that same team so a new hearing aid, a new seat, or a hospital stay does not wipe out a routine that was working.
Frequently asked questions
Is there one AAC device for CHARGE syndrome?
No. Vision, hearing, balance, and fatigue differ widely. An SLP matches access, display size, and vocabulary to the person after a real trial. A diagnosis alone does not pick the device.
Can someone with CHARGE use eye gaze?
Sometimes. Eye gaze needs enough useful vision and a head position the tracker can hold. If either is unreliable, trial a switch, partner-assisted scanning, or direct touch with large targets first. Eye gaze can be revisited later if vision or positioning changes.
What if my child does not answer right away?
Wait longer before you repeat yourself. Processing time is common, especially when the person is also looking, listening, or recovering from sensory work. Agree on a wait time with the SLP and use the same cue each time.
Who starts a home trial?
The person's SLP starts a Forbes AAC home trial, and only after a benefits check. A clinician loan stays with the SLP and does not go home with the family. Calling the office does not by itself send a device.
Will insurance cover a speech-generating device?
Maybe, and maybe not. Medicare, Medicaid, and private plans each have their own rules, and approval is not guaranteed. A funded dedicated device may also limit features that the plan does not cover. A funding specialist can explain the packet. They cannot promise an outcome.
