AAC and Communication Devices for ALS: A Caregiver’s Guide

One of the most profound aspects of ALS caregiving is this: in most cases, the person with ALS remains fully cognitively intact while losing the ability to communicate. They are there — thinking, feeling, processing — even when they can no longer speak, write, or gesture.

Augmentative and alternative communication (AAC) technology is how that connection is maintained. It is not a consolation for the loss of speech. It is a way for the person with ALS to continue being heard, expressing preferences, saying what needs to be said, and participating in their own care.

Starting early matters more than almost anything else in this process.


Why Start Early?

The case for starting AAC planning and implementation early — before speech becomes severely impaired — comes down to two things: banking and learning.

Voice banking is the process of recording the natural voice of the person with ALS while they still have strong, clear speech. These recordings become the voice of a speech-generating device (SGD). The result is a device that speaks in the person’s own voice rather than a generic synthesized voice — which preserves identity and makes communication feel more natural.

Voice banking should start as soon as ALS is diagnosed, ideally in the first weeks or months. The ModelTalker and VocaliD programs are designed specifically for this purpose.

Learning takes time. AAC devices — particularly high-technology systems like eye-gaze devices — have learning curves. Learning to use them while still having some speech and motor function is significantly easier than trying to learn them when communication has severely deteriorated. Many people with ALS who start AAC late wish they had started much earlier.


The Spectrum of AAC Options

AAC ranges from simple, inexpensive tools to sophisticated high-technology systems. The right option depends on current speech, motor function, and the trajectory of decline.

Low-technology AAC:

  • Alphabet boards and word boards — laminated boards with letters, words, or symbols that the person points to or eye-gazes toward
  • Simple gesture systems — established gestures for common communications
  • Partner-assisted scanning — the communication partner speaks letters or options and the person signals yes/no

Low-tech options have no batteries, can’t break down, and are always available as a backup even when high-tech systems are in use.

Mid-technology:

  • Simple speech-generating devices with pre-programmed messages
  • Tablet-based apps (Proloquo4Text, Snap Core First, TouchChat) that convert text or symbols to speech

High-technology eye-gaze devices:

When hand and arm function are severely limited or lost, eye-gaze technology allows the person to control a computer and speech-generating device entirely with their eyes. Systems track the direction of the person’s gaze and translate it into cursor movement and selection.

Major manufacturers: Tobii Dynavox, Eyegaze Edge, PCEye. These devices are sophisticated, expensive ($5,000-15,000+), and can require significant setup and customization — but they maintain communication even in late-stage ALS.

The Speech-Language Pathologist’s Role

A speech-language pathologist (SLP) with AAC specialization is the essential professional in this process. They will:

  • Assess current speech, swallowing, and motor function
  • Recommend appropriate AAC solutions for the current stage and anticipated progression
  • Initiate voice banking before it’s too late
  • Help set up and program the chosen device
  • Train both the person with ALS and caregivers in device use
  • Provide ongoing support as needs change

An SLP at an ALS clinic is the most accessible way to access this expertise. If not connected to an ALS clinic, ask the neurologist for a referral to an SLP with AAC experience.


Insurance and Funding

Medicare: Medicare Part B covers speech-generating devices as Durable Medical Equipment when medically necessary and prescribed by a physician. Coverage requires documentation of severe speech impairment and a prescription. SGDs are covered; tablet-based apps used on consumer devices have more complex coverage. An SLP can help navigate this.

Medicaid: Coverage varies by state. Medicaid typically covers SGDs for eligible individuals meeting medical necessity criteria.

ALS Association and MDA equipment loan programs: Both organizations have equipment loan programs that can provide devices more quickly than the insurance process allows.

eBay and assistive technology recycling programs: Secondhand SGDs can sometimes be found significantly below retail, though they may need reprogramming and updating.


FAQ

AAC (augmentative and alternative communication) refers to all methods and technologies that support communication when natural speech is impaired. For ALS, this ranges from simple alphabet boards to high-technology eye-gaze devices that allow the person to communicate entirely by looking at the screen.

As early as possible — ideally at or shortly after diagnosis. Voice banking, in particular, should start when speech is still strong. Learning to use devices and incorporating them into communication takes time, and starting when some speech remains makes the transition significantly easier.

Yes — through eye-gaze technology, people with ALS who have lost all voluntary movement except eye control can still communicate, write, browse the internet, and in some cases, continue professional work. The technology has advanced significantly and continues to do so.
