AAC device companies: who makes them, what they cost, and how to choose

Last updated 2026-07-09

Who actually makes these devices?

The AAC market is smaller than most people expect, and it splits cleanly in two. A handful of companies make the dedicated speech-generating devices (SGDs) that insurance will fund. A separate group of software companies makes the symbol-based apps that run on iPads and Android tablets. It helps to know which category you're looking at, because funding and clinical support work differently for each.

On the dedicated device side, the four biggest names are Tobii Dynavox, PRC-Saltillo, Lingraphica, and Liberator (owned by Spectronics in Australia, sold under a different setup in North America). These companies build hardware to run their own software, back it with a warranty, and use the HCPCS billing codes insurers ask for. They also run funding departments that walk families through Medicaid and private insurance claims, and that's often where the real legwork happens ^[1].

The app side looks different. AssistiveWare makes Proloquo2Go and Proloquo for Text, both for iOS. Tobii Dynavox sells a tablet app called Snap Core First, and Saltillo (now folded into PRC-Saltillo) makes TouchChat. These run on regular consumer tablets and cost somewhere between $200 and $300 as a one-time purchase, though the tablet itself usually isn't covered by insurance when it's used for AAC ^[2].

A few smaller names are worth knowing too: CoughDrop, browser-based and subscription-priced; Snap Scene from Tobii Dynavox, built for early communicators; and Grid 3 by Smartbox. The field keeps shifting under its own mergers and rebrands: PRC and Saltillo merged back in 2018, which is why you'll still see both names used interchangeably in older clinical paperwork ^[3].

How the major companies compare

Here's a plain comparison of the main players, their flagship products, and approximate price ranges as of mid-2025. Prices for dedicated devices move with insurance negotiations and funding programs, so treat these as starting points, not quotes.

PRC-Saltillo's LAMP Words for Life comes up constantly for kids with childhood apraxia of speech, since it ties each word to a consistent motor pattern instead of relying on symbol locations that keep shifting as the vocabulary grows ^[4].

Tobii Dynavox's eye-gaze hardware sits in its own category. When a child can't reliably use their hands, eye-gaze lets them select symbols just by looking at them, and the I-Series line is the eye-gaze SGD most commonly funded in the US. It costs more, and fitting one is a real process, usually requiring an SLP and often an assistive technology specialist too.

Lingraphica leans toward adults recovering from stroke or traumatic brain injury, so for parents of children it's rarely the first thing anyone suggests. That said, their research library is well organized and worth a read regardless of which device you end up considering ^[5].

Cost and insurance

Dedicated SGDs usually run between $3,000 and $8,000 before any funding. Consumer tablets with AAC apps cost $200 to $600 for the hardware plus $200 to $300 for the app. The gap is real, and features alone don't explain it: you're paying for ruggedized hardware and purpose-built mounts, software licensing, and a company staffed with people who know how to get Medicaid to say yes.

Medicaid covers SGDs as durable medical equipment (DME) under federal law in all 50 states, though the rules vary by state. The billing codes are HCPCS E2500 through E2511 ^[6]. A letter of medical necessity from a licensed SLP, documentation of a trial period, and proof that the device is the least costly option meeting the clinical need are all typically required, and the evaluation itself has to come from an SLP: a parent or teacher's recommendation alone isn't enough.

Private insurance is patchier. Many plans cover SGDs billed as DME with the right HCPCS codes, but first-submission denial rates are high. The AAC company's funding department will help with appeals, which is one honest reason to go through them rather than buying a tablet app and hoping for the best.

For families who can't wait, some states run assistive technology lending programs. ASHA keeps a funding resource page ^[1], and state AT programs list device loans that let a child trial a system before the family commits.

Nobody has clean national data on average out-of-pocket cost after insurance, because it swings so hard by state Medicaid plan, income, and diagnosis. The closest approximation is that Medicaid-eligible children often end up with $0 to a few hundred dollars out of pocket when the process goes smoothly, while private-insurance families frequently face $500 to $2,000+ in cost-sharing even after approval.

What works best for young children and late talkers

Most parents land on this question somewhere between age two and five. The research on early AAC points one direction: starting AAC early doesn't delay natural speech, and it often helps it along ^[7]. The American Speech-Language-Hearing Association's position is unambiguous here.

For a child just starting to communicate, low-tech options like paper core word boards or PECS are often the first step in therapy. Once a child needs more vocabulary faster, apps like Proloquo2Go and TouchChat tend to come next, since they're easy to get started with.

Proloquo2Go only runs on Apple devices, which is a real limitation for some families. That said, AssistiveWare has published peer-reviewed research on vocabulary growth in kids who use the app, and it's one of the most studied AAC apps out there. It uses the SymbolStix and PCS symbol sets and can grow from a small early-communicator layout up to a full vocabulary ^[2].

Kids working through apraxia of speech are often better served by the LAMP Words for Life app (PRC-Saltillo) or the dedicated Accent device, because the motor-planning approach behind them matches how these children actually learn language. A child with apraxia often can't imitate words reliably, so what helps is a system built around steady, repeatable motor routines rather than one optimized for quick symbol searching.

There's no single system that stands out for children on the autism spectrum. What matters more is whether the system offers a full vocabulary from the start rather than just requests and wants, whether the people around the child model it throughout the day, and whether the child has real access to it: it needs to stay within reach and never get taken away as a punishment.

If you're still early in this process, an early intervention evaluation can get your child a no-cost SLP assessment before age three; after that, the school district takes over evaluations under IDEA.

Dedicated device or tablet app: what actually differs

People ask this constantly, and the real answer goes beyond which one costs less.

A dedicated speech-generating device is built for one job. The screen stays readable in sunlight, the case holds up to daily wear, and the speaker is louder and more directional than what you'd get from a tablet. Because the device runs only the AAC software, a child can't wander off into YouTube mid-session. It also comes with a warranty covering AAC-specific use and carries the billing codes Medicaid needs to process reimbursement.

A regular tablet running an AAC app is lighter, cheaper, and far easier to replace if it gets lost or dropped. For a lot of families, especially while they're still figuring out if a system will work, that's the smarter first move. The vocabulary and symbol sets in the major apps hold up well against what's on dedicated hardware, and some speech-language pathologists actually prefer them because they get updated faster than dedicated device software does.

Here's the catch: insurance generally won't pay for the tablet itself, only the app in some cases, and the app's price tag alone rarely meets the threshold for durable medical equipment funding. So if your child qualifies for Medicaid-funded AAC, going with a dedicated device often turns out cheaper in practice, even though the sticker price is higher.

Access matters too. A ruggedized device mounted on a wheelchair is a different tool entirely from an iPad propped up on the counter. For kids with significant physical disabilities, the mounting options, durability, and eye-gaze or switch access built into dedicated hardware do things an app simply can't replicate.

Which AAC companies have the strongest research behind them

Honestly, none of them can point to a randomized controlled trial proving their device beats a competitor's. AAC research is thin across the board, mostly because the population is so varied and large trials are expensive to run. That said, some systems have more published research behind them than others, so it's worth knowing what's actually out there.

Proloquo2Go has the most published research of any single AAC app. A 2014 study by Rispoli and colleagues in the Journal of Developmental and Physical Disabilities looked at requesting behaviors using the app in children with autism, and a 2012 study by van der Meer and colleagues compared it against PECS and speech-alone conditions. The evidence base isn't huge, but it's real and it keeps growing^[7].

Minspeak, the semantic-compaction system used by PRC devices (and Liberator's Vantage), has been around since the 1980s, which gives it a longer track record than most competitors. Research on motor-learning approaches to AAC, including LAMP, is newer but has been consistent in showing benefits for kids who struggle with motor planning^[4].

ASHA's Evidence Maps note that the overall quality of AAC evidence is moderate at best, with most studies being small case series or single-subject designs rather than anything larger^[1]. In practice, SLPs lean on a combination of published research, their own clinical experience, and careful matching of features to a specific child's profile.

So the more useful question to bring to your SLP isn't which device has the best evidence. It's which system fits how your child processes language and how they can physically reach and operate a device.

How AAC funding and insurance actually works

Funding is genuinely complicated, and it's one of the biggest reasons a child waits months between needing a device and actually getting one. Here's the sequence most families go through.

It starts with a full AAC evaluation from a licensed SLP, which is a different animal from a regular speech therapy session. The evaluator looks at language, cognition, motor skills, and vision to figure out which type of AAC fits the child, and that report becomes the backbone of the insurance submission. School-based SLPs can do this evaluation under IDEA, but keep in mind the device they recommend may be approved for school use only, not for home. If you want a device that travels home with your child, you'll likely need a separate medical evaluation.

Next comes the letter of medical necessity. This is where the SLP spells out, in writing, why this particular device is needed and why less expensive options won't do the job. The letter has to line up with the HCPCS billing code and whatever coverage criteria the insurer uses, and the AAC company's funding team can usually provide a template and review the letter before it goes out.

Then there's prior authorization. Almost every insurer and state Medicaid program requires sign-off before the device ships, and that wait can stretch from 30 to 90 days, sometimes longer. Most families lean on a trial device loaned by the AAC company to get through this stretch.

If the request gets denied, and first-time denials are common, that isn't the end of the road. A well-documented appeal that cites clinical necessity and points to the insurer's own coverage policy overturns a lot of these denials. Some families bring in a patient advocate to help with this part.

Medicaid rules for speech-generating devices fall under 42 CFR Part 440, which covers medical equipment and supplies^[6]. Every state has to cover medically necessary DME for Medicaid beneficiaries under 21 through EPSDT (Early and Periodic Screening, Diagnostic, and Treatment), a program with broader coverage rules than adult Medicaid^[11]. For families of children, that's a real lever worth knowing about.

All told, getting from evaluation to device in hand typically takes three to six months once insurance is involved. In the meantime, many families rent or borrow a device through state AT lending programs or directly from the manufacturer.

What to weigh when comparing companies

A few questions matter more than the rest when you're sitting down to compare options.

Start with the vocabulary system: does it use core words? Core word approaches (high-frequency words like "want," "go," "more," "stop") are backed by ASHA guidance and by what we know about language development, while systems built around only nouns or only requests often box a child in later^[1].

Then there's access. A child who reliably uses one finger needs a different setup than a child who uses eye gaze, a head pointer, or a single switch, and not every company supports every access method on every product.

Growth matters too. A toddler might need a dozen symbols; a school-age child might need thousands. Switching systems mid-way through language development is something you want to avoid if at all possible, since the motor patterns and symbol locations all change with a new system.

Support is easy to overlook until you need it. Some companies have strong SLP consultants and real training resources; others are basically software with a manual. Ask directly about onboarding, what happens when the device breaks, and whether there's a loaner policy.

None of that outweighs what the SLP working with your child actually says. An SLP who sees your child regularly has the best read on their motor skills, symbol recognition, and language profile, more than any chart could. Comparison charts like this one are a starting point, not a decision tool.

If you're early in this process, it's worth reading how to find a speech therapist with AAC experience specifically, since that's its own subspecialty and not every clinician has the training. Ask directly before you book an evaluation.

Are there free or low-cost AAC options that actually work?

Yes, and often they're the right place to start, especially early on. You don't need to wait for funding to come through before your child starts communicating.

Low-tech options cost nothing to make. Printed core word boards, PECS cards, and choice boards are nearly free and have solid research behind them. For a child just starting out, a paper board can be the right first step while the family works through funding for a device.

CoughDrop has a free tier with one user and a limited set of boards. The paid version runs $15 to $40 a month, far less than a dedicated device, and it works in any modern browser and syncs across devices, which matters if a child uses an iPad at home and a Chromebook at school.

Open AAC is a community effort building openly licensed symbol sets and board templates, with some SLPs contributing boards directly. Quality varies from one board to the next, but the price is right.

Some school districts fund AAC devices for the school day under IDEA. That device belongs to the school rather than the child, so it stays at school, but it still gives a child access to communication during instructional hours while the family pursues a separate medical device for home and the community.

Worth knowing about: LetMeTalk, a free, open-source AAC app for Android that uses the ARASAAC symbol set, which is used widely around the world. The interface isn't as polished as Proloquo2Go, but it works, and it costs nothing.

Families curious about AI-supported tools might look at Little Words, which uses an adaptive model to build communication boards around a child's specific profile. You can take the quiz at littlewords.ai/start to see whether it fits your child before spending money on something pricier.

None of this replaces a dedicated speech-generating device for a child who needs one. But these options are genuinely useful for trials, for home use alongside a school device, and for families still waiting on insurance to come through.

How do I get an AAC evaluation?

Where you start depends on your child's age and whether there's already a diagnosis in place.

If your child is under three, early intervention should be your first call. Every state runs a program offering free evaluations and services for children birth to three who have developmental delays, and a speech delay by itself is enough to qualify: no diagnosis required ^[10]. Contact your state's program directly, or ask the pediatrician for a referral.

Once a child turns three, the school district takes over evaluations under IDEA. Put your request in writing, and the district has 60 days in most states to complete the process. A school SLP will assess communication needs, and if they decide the child needs an AAC device, the district has to provide one for use at school.

A device your child can take home and out into the world is a different matter, and it usually requires a medical evaluation. You can get one through a pediatric SLP in private practice, a hospital-based AAC center, or a university clinic. University clinics are worth considering since they often charge reduced fees and have strong training behind them: the University of Pittsburgh and Boston University both have long histories in AAC specifically. ASHA runs an SLP finder at asha.org where you can filter by specialty, AAC included ^[1]. When you call around, ask whether the clinician does full AAC evaluations specifically, not just AAC work in general terms. The skill gap between the two is real.

If your child has features on the autism spectrum, getting a diagnosis through your pediatrician or a developmental pediatrician can open the door to Medicaid waiver programs that cover devices at no cost. You don't need to wait on that before pursuing an AAC evaluation: the two processes can move at the same time.

When echolalia is the main way your child communicates, look for an SLP who knows gestalt language processing specifically. A gestalt language processor needs a different AAC approach than a child with minimal verbal output, and not every clinician draws that distinction well ^[8].

Does AAC help or hurt speech development?

Parents often worry that handing a child an AAC device or a picture board takes the pressure off talking, and that the child will stop trying to use their voice. It's a reasonable worry, but the research doesn't back it up.

A 2006 meta-analysis by Millar, Light, and Schlosser in the American Journal of Speech-Language Pathology looked at 23 studies and found that AAC did not get in the way of natural speech development, and in many cases actually supported it ^[7]. ASHA's own clinical guidance says the same thing plainly: "There is no evidence that AAC use inhibits or halts speech development," according to ASHA's practice portal on augmentative and alternative communication ^[1].

The thinking behind this is fairly simple. AAC takes some of the pressure off a child in the moment, letting them join a conversation without the frustration of a speech attempt that doesn't come out right. Once a child can reliably get a need across through a device, they often feel freer to try talking, rather than less motivated to.

This shows up a lot in current research on childhood apraxia of speech. Some evidence suggests motor-planning AAC systems, like LAMP, may actually build the motor groundwork for verbal speech, since practicing on the device reinforces some of the same motor plans a child later uses to speak ^[4].

For minimally verbal children with autism, strong access to AAC lines up with gains in natural speech in some subgroups, though not every child follows this pattern. The 2014 study by Kasari and colleagues in JAMA gets cited often here: it found that adding a speech-generating device to early intervention improved spontaneous communication in minimally verbal school-age children with autism ^[9].

No one can promise a device will make a child start talking. But holding off on AAC while waiting for speech to arrive on its own has no research behind it, and giving children full, early access to AAC is linked to better communication outcomes overall.

Frequently asked questions

What is the most widely used AAC device company?

Tobii Dynavox and PRC-Saltillo are the two biggest names in North America. Tobii Dynavox leads on eye-gaze hardware, while PRC-Saltillo holds the largest share of speech-generating devices for kids with autism and apraxia. On consumer tablets, most families end up with AssistiveWare's Proloquo2Go. None of that should carry more weight than what your SLP actually recommends for your child.

Will Medicaid pay for an AAC device for my child?

In all 50 states, yes. Medicaid covers speech-generating devices as durable medical equipment under HCPCS codes E2500 through E2511, and for kids under 21 the EPSDT benefit requires states to cover medically necessary equipment even in cases where an adult plan wouldn't. You'll need a full AAC evaluation from a licensed SLP plus a letter of medical necessity. The AAC company's funding department can walk you through the submission itself.

What is the difference between Proloquo2Go and TouchChat?

Both are symbol-based apps, but they're built differently. Proloquo2Go, from AssistiveWare, uses the SymbolStix or PCS symbol set and has more published research behind it. TouchChat, from PRC-Saltillo, supports multiple symbol sets and integrates with LAMP Words for Life, which makes it a common pick for kids with apraxia. Proloquo2Go is Apple-only; TouchChat also runs on Android. Price-wise, they're close: both are a one-time purchase around $250.

Can a 2-year-old use an AAC device?

Yes, and often earlier. AAC can be introduced as young as 12 to 18 months once a communication challenge is identified, and there's no minimum age requirement. Starting early doesn't delay speech either: research keeps showing that AAC supports natural speech rather than replacing it. For toddlers, families usually start with simple core word boards or other low-tech systems before moving toward a fully funded dedicated device.

How long does it take to get an AAC device funded through insurance?

Plan on three to six months from evaluation to delivery when Medicaid or private insurance is footing the bill. The evaluation and letter of medical necessity take two to four weeks, prior authorization adds another 30 to 90 days, and an appeal, if you need one, can tack on one to three more months. Most AAC companies loan a trial device during this stretch, and families with urgent needs can sometimes move faster through state assistive technology lending programs.

What AAC device is best for autism?

There isn't one, since communication profiles differ so much from child to child. ASHA recommends a feature-matching approach instead: the device should fit the child's motor skills, symbol recognition, and language stage. Proloquo2Go and TouchChat are the apps most commonly used, and for kids who have both autism and motor-planning difficulties, LAMP Words for Life (PRC-Saltillo) comes up often. This decision should be led by an SLP with real AAC experience.

Does an AAC device require a diagnosis to get?

No, you can start using or buying AAC without one. Insurance funding just requires documented evidence of a complex communication need, which an SLP establishes through evaluation rather than a formal diagnosis. That said, a diagnosis like autism or cerebral palsy can open the door to Medicaid waiver programs that cover devices at no cost. An early intervention evaluation, available to any child under three with delays, doesn't require a prior diagnosis either.

What is Minspeak and which companies use it?

Minspeak is a semantic-compaction system Bruce Baker developed in the 1980s. It works through sequences of symbol presses, where each symbol carries several meanings depending on context, so users can reach large vocabularies with a small number of keys. PRC-Saltillo's Accent series and Liberator devices both run Minspeak-based vocabulary programs like Unity. The learning curve is steeper than grid-based systems, but once it clicks, communication moves faster.

Can a child use AAC and still work on verbal speech in therapy?

Yes, and that's the standard approach, not an exception. AAC runs alongside speech therapy rather than replacing it, and most SLPs who work with AAC users keep targeting verbal speech whenever that's a realistic goal. Several studies back this up, including a 2006 meta-analysis in the American Journal of Speech-Language Pathology, which found AAC use didn't reduce verbal speech attempts and often increased them.

What is eye-gaze AAC and which companies make it?

Eye-gaze AAC uses infrared cameras to track where someone is looking on a screen, so they can select symbols without moving their hands or body. Tobii Dynavox's I-Series is the eye-gaze SGD most commonly funded in the U.S., and Smartbox also makes compatible hardware for its Grid 3 software. Getting set up requires an in-person fitting with an SLP, often alongside an assistive technology specialist, to calibrate the system for the individual user.

What questions should I ask an SLP before an AAC evaluation?

Ask how many AAC evaluations they do each year and whether they've worked with your child's specific diagnosis before. Ask which symbol sets and access methods they know well, and whether the evaluation will cover both a school-use device and a home-and-community device, since those often go through separate processes. It's also worth asking who handles the insurance submission and whether the practice has a funding specialist on hand. A good AAC-focused SLP will expect these questions and won't dodge them.

Is CoughDrop a real AAC system or just for schools?

It's a legitimate platform used across home, school, and clinical settings, not just schools. CoughDrop runs in a web browser and on iOS and Android apps, so it isn't tied to one device. The free tier covers one user with limited boards, while paid plans run $15 to $40 a month for unlimited boards and team access. Medicaid won't fund it as durable medical equipment, but it's a solid option during a trial phase or for families who can't get insurance funding.

What happens to the AAC device if the company goes out of business?

It's a real concern that doesn't get talked about enough. When PRC and Saltillo merged in 2018, families with devices from either side saw their software change over time. Generally, dedicated device companies keep providing updates for years after a product is discontinued, but app-based systems sit on shakier ground since one iOS update can break things. It's worth asking any company upfront about their update and legacy support policy. Tobii Dynavox and PRC-Saltillo are big enough that a sudden shutdown is unlikely, though never impossible.

How is AAC different for adults versus children?

Adults who need AAC after a stroke, TBI, or ALS are working from a different starting point than children building language from scratch. Adult systems tend to prioritize pre-stored phrases, text-to-speech for people who already read and write, and fast message banking, and Lingraphica specializes in adult aphasia specifically. Children's systems focus more on vocabulary growth, symbol-based access, and layouts that can grow alongside their language. Some companies, including Tobii Dynavox and PRC-Saltillo, serve both groups but keep the product lines separate. Either way, an SLP should be matching the system to the person, not the other way around.
