10-Minute Speech Practice That Doesn't Require Sitting Still

Last updated 2026-07-09

What companies actually make AAC devices?

The AAC market is smaller than most people expect. A handful of companies make the dedicated speech-generating devices (SGDs) that insurance will fund. A separate layer of software companies makes the symbol-based apps that run on iPads and Android tablets. Knowing which category you're looking at matters for funding and for clinical support.

The four biggest names in dedicated SGDs are Tobii Dynavox, PRC-Saltillo, Lingraphica, and Liberator (owned by Spectronics in Australia but sold in North America). These companies sell hardware that runs their own software, comes with a warranty, and carries the HCPCS billing codes insurers require. They also have funding departments that help families deal with Medicaid and private insurance, which is often where the real work happens ^[1].

On the app side, AssistiveWare makes Proloquo2Go and Proloquo for Text, both for iOS. Tobii Dynavox sells a tablet app called Snap Core First. Saltillo (now part of PRC-Saltillo) makes TouchChat. These apps run on consumer hardware and cost $200 to $300 as a one-time purchase, but the tablet itself is usually not covered by insurance for AAC use ^[2].

A few smaller players are worth knowing: CoughDrop (browser-based, subscription model), Snap Scene (Tobii Dynavox, for early communicators), and Grid 3 by Smartbox. The field keeps shifting. PRC and Saltillo merged in 2018, so you'll see their names used interchangeably in older clinical documents ^[3].

How do the major AAC device companies compare?

Here is 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 gets recommended a lot for children with childhood apraxia of speech because it ties each word to a consistent motor pattern, rather than leaning on symbol locations that shift as vocabulary grows ^[4].

Tobii Dynavox's eye-gaze hardware is a category apart. If a child can't reliably use their hands, eye-gaze lets them pick symbols by looking at them. The I-Series line is the most commonly funded eye-gaze SGD in the US. It's expensive, and the fitting process is genuinely complicated, needing an SLP and often an assistive technology specialist.

Lingraphica skews toward adults recovering from stroke or TBI. For parents of children, it's rarely the first recommendation. Their research library is well organized and worth reading no matter which device you're weighing ^[5].

How much do AAC devices cost, and does insurance cover them?

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.

Dedicated devices cost so much partly because of the hardware (ruggedized casing, purpose-built mounts), partly the software licensing, and partly the company's funding support staff. You are paying for 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. The evaluation has to be done by an SLP. A parent or teacher's recommendation alone is not 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 for insurance, 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.

One honest note: 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. Private-insurance families frequently face $500 to $2,000+ in cost-sharing even after approval.

What AAC systems are best for young children and late talkers?

Age two to five is where most parents show up with this question. The research on early AAC points one direction: starting AAC early does not delay natural speech and often helps it ^[7]. The American Speech-Language-Hearing Association's position is unambiguous here.

For young children just starting to communicate, low-tech AAC (paper core word boards, PECS) is often the first step in therapy. For kids who need more vocabulary faster, apps like Proloquo2Go and TouchChat are frequently the first digital step because the barrier to entry is low.

Proloquo2Go runs only on Apple devices, which is a real constraint. AssistiveWare has published peer-reviewed research on vocabulary growth in children using the app, and it's one of the most studied AAC apps in the literature. The app uses the SymbolStix and PCS symbol sets and scales from a small early-communicator layout to a full vocabulary ^[2].

For children with apraxia of speech, the LAMP Words for Life app (PRC-Saltillo) or the dedicated Accent device gets recommended specifically because the motor-planning approach matches how those children learn language. A child with apraxia often can't imitate words reliably, so a system that builds steady motor routines matters more than one tuned for fast symbol finding.

For children on the autism spectrum, the evidence doesn't point to one system. What matters more: the system offers a full vocabulary from the start (more than requests and wants), communication partners model it throughout the day, and the child has genuine access, meaning it's always within reach and never taken away as a consequence.

If you're early in figuring this out, an early intervention evaluation can get your child a no-cost SLP assessment before age three. After three, the school district takes over evaluation duties under IDEA.

What is the difference between a dedicated AAC device and an AAC app on a tablet?

This is the most common practical question, and the answer runs deeper than the price difference alone.

A dedicated SGD is purpose-built. The screen is brighter and readable in sunlight. The case is tougher. The speaker is louder and more directional. The device runs only the AAC software, so a child can't accidentally wander off to YouTube. It comes with a warranty covering AAC-specific use, and it carries the billing codes Medicaid needs for reimbursement.

A consumer tablet with an AAC app is lighter, cheaper, and easier to replace if lost or broken. For many families, especially in a trial phase, it's the right first step. The vocabulary and symbol systems in the major apps are genuinely comparable to what runs on dedicated hardware. Some SLPs argue the apps are actually more current because they update faster than dedicated device software.

The catch: insurance won't fund the tablet itself, only the app in some cases, and the per-item cost of the app alone often doesn't trigger DME funding. So if your child qualifies for Medicaid-funded AAC, a dedicated device often ends up being the more financially rational choice even though it costs more on paper.

There's also an access question. A ruggedized device on a wheelchair mount is a different tool than an iPad on the kitchen counter. For children with significant physical disabilities, the mounting, durability, and eye-gaze or switch options on dedicated hardware matter in ways no app can copy.

Which AAC companies have the best evidence behind their systems?

Evidence in AAC is genuinely thin in some areas. Most studies have small samples because the population varies so much and money for large randomized trials is scarce. Still, some systems have more research behind them than others.

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 enormous, but it exists and keeps growing ^[7].

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

The honest answer: no company has a randomized controlled trial showing its device beats a competitor's. ASHA's Evidence Maps note the overall quality of AAC evidence is moderate at best, with most studies being small case series or single-subject designs ^[1]. What SLPs lean on is a mix of published research, clinical experience, and careful feature matching to a specific child's profile.

For parents, this means the right question to ask an SLP isn't "which device has the best evidence." It's "which system matches how my child processes language and how they physically reach a device."

How does the AAC funding and insurance process actually work?

The funding process is genuinely complicated, and it's one of the biggest sources of delay between a child needing a device and getting one. Here is the sequence most families move through.

First, a full AAC evaluation by a licensed SLP. This is not the same as a regular speech therapy session. It assesses language, cognition, motor skills, and vision to decide which type of AAC fits. The evaluation report becomes the core of the insurance submission. School-based SLPs can do this under IDEA, but the device they recommend may be for school use only, not for home and community. A separate medical evaluation is often needed for a device that goes home.

Second, the letter of medical necessity. This is the SLP's document explaining why the child needs a specific device and why cheaper alternatives fall short. It has to match the HCPCS code being billed and the insurer's coverage criteria. The AAC company's funding team can supply templates and review the letter before submission.

Third, prior authorization. Most insurers and state Medicaid programs require this before the device ships. The wait can run 30 to 90 days or longer. During this window, a trial device loaned by the AAC company is usually in use.

Fourth, appeal if denied. First-time denial rates are high, but a denial doesn't end the case. A well-documented appeal citing clinical necessity and the insurer's own coverage policy overturns many denials. Some families use a patient advocate for this step.

Medicaid rules for SGDs sit under 42 CFR Part 440, which covers medical equipment and supplies ^[6]. Every state must cover medically necessary DME for Medicaid beneficiaries under age 21 through EPSDT (Early and Periodic Screening, Diagnostic, and Treatment), which has broader coverage requirements than adult Medicaid ^[11]. This is a meaningful lever for families of children.

Total time from evaluation to device in hand is often three to six months when insurance is involved. Families sometimes rent or borrow a device during that window through state AT lending programs or straight from manufacturers.

What should parents look for when comparing AAC companies?

When you sit down to compare options, these are the questions that matter.

Does the vocabulary system 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. Systems that start with only nouns or only requests often limit a child later ^[1].

What is the access method? 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. Not every company supports every access method on every product.

How does the vocabulary grow? A good system scales. A toddler might need 12 symbols. A school-age child might need 3,000. You don't want to switch systems mid-language-development if you can avoid it, because the motor patterns and symbol locations change.

What support does the company actually give? Some companies have strong SLP consultants and training resources. Others are basically software-only. Ask specifically about onboarding support, what happens when the device breaks, and what the loaner policy is.

What does the SLP say? This sounds obvious, but it's the most predictive factor. An SLP who works with your child regularly has the best read on their motor skills, symbol recognition, and language profile. App-based comparison charts (including this one) are a starting point, not a decision tool.

For families early in the process, the speech therapy article on this site walks through how to find an SLP with AAC experience, which is its own subspecialty. Not every speech therapist has AAC training, and it's worth asking directly before booking an evaluation.

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

Yes. Free and low-cost options are real and often appropriate, especially early in the process.

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

CoughDrop offers a free tier with one user and limited boards. The paid tier is $15 to $40 per month, far less than a dedicated device. It runs in any modern browser and syncs across devices, which helps a child who has both a home iPad and a school Chromebook.

Open AAC is a community-led effort to create openly licensed symbol sets and board templates. Some SLPs contribute boards directly. Quality varies, but the price is right.

Some school districts fund AAC devices for the school day under IDEA. The device belongs to the school, not the child, so it can't go home, but it gives a child access to communication during instructional hours while the family pursues a separate medical device for home and community use.

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

For families exploring AI-supported tools, Little Words is one option that uses an adaptive model to build communication boards around a child's specific profile. Take the quiz at littlewords.ai/start to see whether the approach fits your child before committing to anything pricier.

None of these free options replace a dedicated SGD for a child who needs one. But they're genuinely useful for trials, for home use alongside a school device, and for families waiting on insurance.

How do I get an AAC evaluation for my child?

The evaluation pathway depends on your child's age and whether they already have a diagnosis.

Under age three, early intervention is the right first call. Every state runs an early intervention program that provides free evaluations and services for children birth to three with developmental delays. A speech delay is enough to qualify for an evaluation; you don't need a diagnosis first ^[10]. Contact your state's early intervention program directly, or ask the pediatrician for a referral.

Age three and older, the school district handles evaluations under IDEA. Request an evaluation in writing. The district has 60 days in most states to complete it. The school SLP assesses communication needs. If they decide the child needs an AAC device, the district must provide it for school use.

For a device the child takes home and into the community, a medical evaluation is usually necessary. That happens through a pediatric SLP in private practice, a hospital-based AAC center, or a university clinic. University AAC clinics often have reduced fees and strong training programs. Places like the University of Pittsburgh and Boston University have longstanding AAC specialties.

ASHA has an SLP finder tool at asha.org that lets you filter by specialty, including AAC ^[1]. When you call, ask specifically whether the clinician does full AAC evaluations, more than AAC in general. There is a real skill difference.

If your child has autism spectrum features, a diagnosis through your pediatrician or a developmental pediatrician can open Medicaid waiver programs that fund devices at no cost. The diagnosis process and the AAC evaluation can run in parallel. You don't have to wait for one to start the other.

For children where echolalia is the main communication pattern, look specifically for an SLP familiar with gestalt language processing. The AAC approach for a gestalt language processor differs from the approach for a child with minimal verbal output, and not every clinician tells them apart well ^[8].

What does the research say about AAC and speech development?

The fear that AAC will replace speech or sap a child's motivation to talk is common and understandable. The evidence does not support it.

A 2006 meta-analysis by Millar, Light, and Schlosser in the American Journal of Speech-Language Pathology examined 23 studies and found that AAC did not inhibit natural speech development and in many cases supported it ^[7]. ASHA's clinical guidance reflects this: "There is no evidence that AAC use inhibits or halts speech development," per ASHA's practice portal on augmentative and alternative communication ^[1].

The proposed mechanism is that AAC eases the communicative pressure on a child, letting them join a conversation without the distress of failed speech attempts. A child who can reliably express a need through a device may then feel less anxious about trying verbal speech.

For children with childhood apraxia of speech, the link between AAC and speech development is especially active in current research. Some evidence suggests motor-planning AAC systems (like LAMP) may build the motor foundations for verbal speech, because device practice reinforces the same motor plans the child uses for verbal output ^[4].

For minimally verbal children with autism, strong AAC access correlates with gains in natural speech in some subgroups, though not all. The 2014 study by Kasari and colleagues in JAMA is often cited here; it found that adding a speech-generating device to early intervention improved spontaneous communication in minimally verbal school-age children with autism ^[9].

Nobody should promise that AAC will make a child verbal. What the evidence supports is this: withholding AAC while waiting for verbal speech has no research behind it, and early, full AAC access is tied to better communication outcomes broadly defined.

Frequently asked questions

What is the most widely used AAC device company?

Tobii Dynavox and PRC-Saltillo are the two largest AAC device companies in North America by market share. Tobii Dynavox leads the eye-gaze hardware segment; PRC-Saltillo has the largest share of speech-generating devices for children with autism and apraxia. AssistiveWare's Proloquo2Go is the most widely used AAC app on consumer tablets. Your SLP's recommendation should outweigh market share in any decision.

Will Medicaid pay for an AAC device for my child?

Yes, in all 50 states. Medicaid covers speech-generating devices as durable medical equipment under HCPCS codes E2500 through E2511. For children under 21, the EPSDT benefit requires states to cover medically necessary equipment even when their adult Medicaid plan would not. You need a full AAC evaluation by a licensed SLP and a letter of medical necessity. The AAC company's funding department can guide the submission.

What is the difference between Proloquo2Go and TouchChat?

Both are symbol-based AAC apps. Proloquo2Go by AssistiveWare uses the SymbolStix or PCS symbol set and has the larger published research base. TouchChat by PRC-Saltillo supports multiple symbol sets and integrates with LAMP Words for Life, a common choice for children with apraxia. Proloquo2Go runs only on Apple devices; TouchChat also runs on Android. Both cost about $250 as a one-time purchase.

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

Yes. AAC can be introduced as early as 12 to 18 months in children with identified communication challenges. There is no minimum age, and early AAC use does not delay speech development. Research consistently shows early AAC supports rather than replaces natural speech. Simple core word boards or low-tech systems are common starting points for toddlers before a family pursues a fully funded dedicated device.

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

Typically three to six months from evaluation to device delivery when Medicaid or private insurance is involved. The evaluation and letter of medical necessity take two to four weeks. Prior authorization review adds 30 to 90 days. Appeals, if needed, can add another one to three months. AAC companies loan trial devices during this window. Families in acute need can sometimes get a device faster through state assistive technology lending programs.

What AAC device is best for autism?

No single device fits all autistic children, because communication profiles vary widely. ASHA recommends a feature-matching approach: the device should match the child's motor skills, symbol recognition, and language stage. Proloquo2Go and TouchChat are the most commonly used apps. For children with both autism and motor-planning difficulties, LAMP Words for Life (PRC-Saltillo) is frequently recommended. An SLP with AAC experience should lead the decision.

Does an AAC device require a diagnosis to get?

No diagnosis is required to start using or buying AAC. For insurance funding, you need documented evidence of a complex communication need, which an SLP records through the evaluation, not a medical diagnosis as such. A diagnosis of autism, cerebral palsy, or another condition can trigger Medicaid waiver programs that fund devices at no cost. An early intervention evaluation, open to all children under three with delays, does not require a prior diagnosis.

What is Minspeak and which companies use it?

Minspeak is a semantic-compaction system developed by Bruce Baker in the 1980s. It uses sequences of symbol presses, where each symbol carries multiple meanings depending on context, letting users reach large vocabularies quickly with a small number of keys. PRC-Saltillo devices (Accent series) and Liberator devices both use Minspeak-based vocabulary programs like Unity. It has a steeper learning curve than grid-based systems but allows faster communication once learned.

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

Yes, and this is the standard approach. AAC is not an either/or alternative to speech therapy; it runs alongside it. Most SLPs who work with AAC users also target verbal speech production when it's a realistic goal. The two approaches complement each other. Multiple studies, including a 2006 meta-analysis in the American Journal of Speech-Language Pathology, found that AAC use did not 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 a user looks on a screen, letting them select symbols without hand or body movement. Tobii Dynavox's I-Series is the most commonly funded eye-gaze SGD in the United States. Smartbox also makes eye-gaze compatible hardware for its Grid 3 software. Eye-gaze systems require an in-person fitting with an SLP and often an assistive technology specialist to calibrate for each user.

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

Ask how many AAC evaluations they complete per year and whether they have experience with your child's specific diagnosis. Ask which symbol sets and access methods they know. Ask whether the evaluation covers both a school-use device and a home-and-community device, since these can require separate processes. Ask who handles insurance submission and whether the practice has a funding specialist. A good AAC SLP will expect these questions and answer them directly.

Is CoughDrop a real AAC system or just for schools?

CoughDrop is a legitimate AAC platform used by children and adults in home, school, and clinical settings. It runs in a web browser and on iOS and Android apps, so it's device-agnostic. The free tier supports one user with limited boards. Paid plans run $15 to $40 per month and allow unlimited boards and team access. Medicaid does not fund it as DME, but it's a practical option for families in the trial phase or those who can't access insurance funding.

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

This is a real and underappreciated concern. PRC and Saltillo merged in 2018; families with devices from either company saw software changes over time. Dedicated device companies generally provide software updates for several years after a product is discontinued. App-based systems are more vulnerable, since an iOS update can break an app. When choosing a system, ask the company about its update and legacy support policy. Big companies like Tobii Dynavox and PRC-Saltillo have enough market presence to make a sudden shutdown unlikely but not impossible.

How is AAC different for adults versus children?

Adults acquiring AAC after a stroke, TBI, or ALS have different needs than children building language for the first time. Adult systems often prioritize pre-stored phrases, text-to-speech for existing literacy, and fast message banking. Lingraphica specializes in adult aphasia. Children's systems prioritize vocabulary growth, symbol-based access, and layouts that grow with language. Some companies, like Tobii Dynavox and PRC-Saltillo, serve both populations with separate product lines. An SLP should always match the system to the individual's communication profile.
