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

Last updated 2026-07-09

What is a high tech AAC device?

A high tech AAC device is any electronic system that helps a person communicate when speech alone isn't enough. AAC stands for augmentative and alternative communication, a field that covers everything from simple picture boards to full voice-output computer systems. The "high tech" label means the device runs on power and produces output electronically, usually synthesized or recorded speech.

The American Speech-Language-Hearing Association (ASHA) defines AAC as "all of the ways we share our ideas and feelings without talking," and high tech devices sit at the most feature-rich end of that spectrum ^[1]. They store thousands of vocabulary words. They speak aloud in natural-sounding voices. They adapt to a user's motor abilities through touch, eye gaze, or switch scanning.

High tech devices sit at one end of a spectrum. On the other end are low tech AAC devices like paper boards, PECS binders, and alphabet charts. Low tech AAC devices cost almost nothing, need no batteries, and never crash. High tech AAC devices do things no paper board can: they speak aloud in a crowd, they store complex phrases, and they grow with the user. Most kids who use AAC end up using both, depending on the situation.

If you're just starting to explore the whole AAC landscape, the overview article on AAC devices is the best place to get grounded before reading this one.

What are the main types of high tech AAC devices?

There are three broad categories of high tech AAC devices. Understanding them saves you from expensive wrong turns.

Dedicated speech-generating devices (SGDs) These are purpose-built computers whose only job is communication. Brands like Tobii Dynavox, PRC-Saltillo, and Lingraphica make the most widely prescribed models. They're ruggedized, spill-resistant, and designed for full-day use. Many qualify for Medicaid or insurance coverage as durable medical equipment (DME). The tradeoff is price: dedicated SGDs typically run $5,000, $12,000 before insurance ^[2].

App-based AAC on consumer tablets Apps like Proloquo2Go, TouchChat, LAMP Words for Life, and Snap Core First run on an iPad or Android tablet. The app itself costs $150, $350; the tablet adds another $300, $800. Total out-of-pocket is dramatically lower than a dedicated device, and many families start here. The downside is durability (a dropped iPad is just a dropped iPad) and the fact that some insurers won't cover consumer hardware as DME.

Eye-gaze and alternative-access systems For children with significant motor involvement who can't reliably touch a screen, eye-gaze systems track where the user is looking and select symbols or letters accordingly. Tobii's eye-tracking hardware is the most prescribed in the United States. These systems are almost always dedicated devices and sit at the higher end of the cost range.

Within all three categories, software can be organized around different vocabulary frameworks:

There's no universally best framework. A child with apraxia of speech may do best with motor-planning layouts like LAMP, because consistent motor patterns support speech development alongside device use ^[3]. A child who already reads may do well with spelling-based access. This is exactly the kind of decision a speech-language pathologist should drive, not a device vendor.

How much do high tech AAC devices cost?

Cost is the number parents ask about first, and the honest answer is that it ranges enormously.

These figures reflect 2024 to 2025 retail pricing reported by device manufacturers and corroborated by Medicaid funding documentation ^[2][4].

Here's the part that matters: most families with documented medical necessity do not pay list price. Medicaid covers dedicated SGDs in all 50 states under the durable medical equipment benefit, and the coverage rate is often 100% for medically necessary devices after an SLP evaluation ^[4]. Private insurance coverage varies a lot by plan, but the Affordable Care Act's essential health benefits rules push many plans toward covering SGDs when the device is classified as DME.

App-based systems are trickier to fund. Because Medicaid generally won't pay for a consumer tablet as DME, some families buy the app themselves and request reimbursement only for the mount, case, or stylus. Others apply to nonprofit funding sources like the United Healthcare Children's Foundation or the AAC Institute while waiting for insurance decisions.

One practical note. The $8,000, $12,000 retail price on dedicated devices is largely a negotiated starting point between manufacturers and payers. If your family is paying out of pocket, call the manufacturer directly. Most have hardship pricing or loan programs.

Who actually needs a high tech AAC device vs. low tech options?

This is genuinely not a straightforward answer, and anyone who tells you otherwise is selling something.

Low tech AAC devices (picture boards, PECS books, alphabet charts, communication wallets) work for a huge range of communicators. They're portable, never run out of battery, and can be made for under $20. Research consistently shows that low tech and high tech AAC are not in competition; most strong communicators use both depending on context ^[1].

That said, high tech devices offer things low tech cannot. Synthesized voice output means a stranger in a grocery store can understand your child without learning a symbol system. Stored phrases let a child express complex thoughts faster than pointing through a binder. Dynamic displays hold thousands of vocabulary words without physical bulk.

The question is not "is my child ready for high tech AAC?" The question is whether high tech tools would meaningfully expand their communication right now. ASHA's position is that there is no prerequisite cognitive or language level required before introducing AAC; waiting for a child to be "ready" is not supported by evidence ^[1].

Practically, a high tech device tends to be worth pursuing when:

• The child has enough intentional motor control to activate a touchscreen, switch, or gaze system (even if the movements are limited)
• The family can commit to learning the device alongside the child
• Voice output is meaningfully different from what the child can produce vocally
• Low tech systems are being outgrown or aren't functional in key environments

Children with childhood apraxia of speech or significant autism spectrum communication challenges are among the most common candidates, but AAC is not exclusive to any diagnosis. An SLP specializing in AAC is the right person to do the formal feature matching.

How does an AAC evaluation actually work?

An AAC evaluation is a specialized assessment done by a speech-language pathologist, ideally one with specific AAC training or certification. It is not the same as a general speech-language evaluation.

The SLP looks at several things: the child's current communication methods (including any vocalizations, gestures, or eye contact), motor skills (hand control, head control, visual tracking), cognitive and language skills, sensory needs, and the environments where communication needs to happen. They then run a "feature matching" process, comparing the child's profile to the features of different devices and access methods.

For insurance or Medicaid funding, the evaluation must include a formal written report documenting medical necessity. That usually means showing that the child has a communication impairment that significantly limits daily functioning, and that the specific device requested is the least expensive option that meets the child's needs. The Centers for Medicare and Medicaid Services (CMS) has published guidance on SGD coverage criteria ^[4].

The evaluation usually includes a trial period with one or more devices. Many SLP practices and AAC manufacturers have loan programs. Tobii Dynavox, PRC-Saltillo, and others all offer short-term device trials. Never commit to a device your child hasn't tried first.

If your child has an IEP, the school district may be obligated to conduct an AAC evaluation at no cost to the family under IDEA (Individuals with Disabilities Education Act), if the team agrees the child may benefit from AAC as a related service ^[5]. School-provided devices are for educational use; they stay at school. A personally owned device obtained through insurance goes everywhere. Many families pursue both tracks at once.

To find a qualified SLP, ASHA's Find a Professional directory filters by specialty area including AAC ^[1]. Learn more about working with a specialist in our article on speech therapy.

Can insurance or Medicaid pay for a high tech AAC device?

Yes, and this is one of the most important things for families to understand.

Medicaid covers speech-generating devices in all 50 states. CMS published clarifying guidance in 2001 confirming that SGDs qualify as covered DME when a physician or licensed healthcare provider documents medical necessity ^[4]. The coverage rate is typically 100% of allowable cost after a qualifying evaluation. The documentation burden is real, but the coverage exists.

Private insurance is less consistent. Under the ACA, plans on the individual and small group markets must cover "habilitative services" as essential health benefits, and SGDs often qualify under durable medical equipment or rehabilitation technology benefits. The exact coverage depends on the plan language. Many families get an initial denial and win on appeal, especially when the SLP submits a strong letter of medical necessity with functional impact documentation.

For children under 21 on Medicaid, the Early and Periodic Screening, Diagnostic and Treatment (EPSDT) benefit matters most. EPSDT requires states to cover any medically necessary service for children under 21 even if that service isn't otherwise covered by the state's Medicaid plan ^[6]. This is often the funding path for children whose standard Medicaid SGD benefit has gaps.

For families who don't qualify for Medicaid and have poor private insurance, nonprofit routes include:

• AAC Institute (aacInstitute.org)
• United Healthcare Children's Foundation
• Variety, the Children's Charity
• State assistive technology programs (every state has one under the AT Act of 2004 ^[7])

The AT Act programs often have low-interest loans, device lending libraries for trials, and reuse programs where you can get a donated SGD at little or no cost ^[7].

What are the most widely used high tech AAC device brands and apps?

The AAC market is dominated by a handful of companies, and knowing the landscape helps you ask better questions in an evaluation.

Tobii Dynavox The largest AAC company in the world after Tobii's acquisition of Dynavox. Their product line runs from the Snap Core First app (available on iPads and Windows tablets) to dedicated hardware like the TD Snap and I-Series eye-gaze systems. Tobii Dynavox is the most commonly prescribed SGD brand in the United States according to AAC funding data ^[2].

PRC-Saltillo Formerly Prentke Romich Company, PRC-Saltillo makes the Unity vocabulary system and the LAMP Words for Life app. Their hardware line includes the Accent series. PRC-Saltillo is closely associated with motor-planning AAC approaches and is frequently recommended for apraxia of speech.

Lingraphica Mostly focused on adults recovering from aphasia or stroke, Lingraphica makes the TouchTalk and AllTalk devices. Worth mentioning here for families with teenagers aging out of pediatric systems, or adults seeking speech therapy options.

AssistiveWare The maker of Proloquo2Go and Proloquo4Text, both for iPad. Proloquo2Go is the most widely used AAC app globally and has the largest research base among app-based systems. It runs on iOS only.

Saltillo / Metacom Makes TouchChat HD with WordPower, another highly prescribed app available on iOS and Android.

Beyond these, there are dozens of smaller apps. Some parents ask about free options: Cboard and CommunicoTe are free or low-cost grid-based apps with smaller vocabulary sets, fine for early exploration but generally not enough for a full-time AAC user.

How long does it take for a child to learn to use a high tech AAC device?

This is the question device vendors tend to underplay and SLPs tend to be most honest about.

Learning AAC is not like learning to use an app. It's learning a language. Most researchers who study AAC acquisition compare it to first language learning in typical development: it takes time, consistent exposure, and a communication partner who models the language regularly ^[3].

The most important practice in AAC intervention is "aided language input" or "modeling," where a parent, SLP, or teacher uses the device themselves to communicate while talking to the child. The child watches a competent user and learns the system through observation and interaction, not drills. This sounds simple. It is actually a big commitment that takes training and daily repetition.

There's no clean data on average acquisition timelines because it varies so much by the child's age, the presence of other disabilities, the amount of modeling happening at home, and the fit of the vocabulary chosen. What the research does say: children who get steady modeling from caregivers make faster progress, and restricting AAC use ("we'll try it at therapy first") slows things down ^[3].

Expect a minimum of three to six months before a new device user is communicating flexibly and independently. Some children take a year or two. Some children, especially older adopters or those with significant cognitive disabilities, may always need real support from a communication partner. None of this means the device isn't working. It means AAC is a relationship, not a product.

Early intervention matters here too. Children who start AAC younger tend to build larger vocabularies and develop more independent communication over time.

Does using AAC stop a child from learning to talk?

No. This is probably the most persistent myth in AAC, and the evidence flatly contradicts it.

A 2006 meta-analysis by Millar, Light, and Schlosser examined 23 studies of AAC intervention and found that in 89% of participants, speech either increased or stayed the same after AAC was introduced ^[8]. No study in the analysis showed meaningful speech reduction following AAC introduction.

As the authors concluded, their findings "provided strong evidence that AAC interventions do not impede speech production" ^[8].

The fear that giving a child a device will make them "lazy" about speaking comes from a reasonable intuition that turns out to be wrong. Communication is communication; more of it in any form tends to support more of it in every form. Children who have a reliable way to make themselves understood are less frustrated, more motivated to interact, and often more willing to attempt speech.

For children with childhood apraxia of speech specifically, some AAC systems (particularly those built on motor-planning frameworks like LAMP) may actively support speech development by pairing consistent articulatory models with symbol selection. This is an active area of research.

The American Academy of Pediatrics (AAP) recommends that children with communication delays be referred for evaluation and that AAC be considered as part of early intervention, not held back until speech fails ^[9].

What should parents look for when choosing between high tech AAC devices?

The feature-matching process an SLP does formally, you can begin informally by asking these questions.

Access method first. How does the child physically interact with the world? A child with reliable finger pointing uses direct touch. A child with limited hand control may need a keyguard (a plastic overlay with holes over each button), switch scanning, or eye gaze. The access method narrows the device list dramatically.

Vocabulary framework second. Does your child learn better through pictures or words? Does their SLP have a strong view on motor-planning vs. grid-based organization? The framework shapes how much practice the whole family has to do together.

Durability for real life. Dedicated devices are built for drops and moisture. iPads in protective cases (Otterbox Defender, Heckbo cases) are reasonably durable but not equivalent. If your child throws things, test the case before committing.

Voice quality. Your child will use this voice for years. Listen to the available voices carefully; many devices offer multiple options. Acapela and Nuance Vocalizer are commonly used voice engines across brands.

Growth ceiling. A device that works for a four-year-old should still work for a fourteen-year-old. Ask how many vocabulary words the system can store and how vocabulary is organized as complexity grows.

Family and school adoption. The best device in the world fails if no one around the child knows how to use it. Ask whether the device maker offers training for families and teachers, and whether there's a local consultant in your area.

If you're supplementing therapy at home, tools like Little Words can help parents practice modeling language in everyday moments between sessions. It's not a replacement for a dedicated AAC evaluation, but consistent daily exposure matters and home-based tools fill real gaps.

How is a high tech AAC device different from a simple tablet or speech app?

A useful question, because the line has blurred a lot in the last decade.

Ten years ago, the answer was simple: dedicated SGDs were specialized hardware, tablets were consumer entertainment devices, and there was no meaningful overlap. Now, apps like Proloquo2Go run on standard iPads and produce communication output that is functionally equivalent to many dedicated devices.

The real differences today are:

Durability and purpose-building. Dedicated SGDs are designed to survive a school day. They often have rubberized housing, reinforced screens, and built-in handles. They don't have a YouTube app waiting to distract a child.

Funding classification. CMS and most insurers will fund a dedicated SGD as DME. They generally won't fund a consumer iPad as DME, though some states have Medicaid waiver programs that cover the tablet itself.

Mounting and access hardware. Dedicated devices often connect to wheelchair mounts, adjustable arms, and switch access hardware more cleanly than tablets, though tablet mounting solutions have improved.

Single-purpose integrity. A dedicated device does one thing: communication. That matters in school settings where a tablet might be taken away for non-AAC use, or where a child's device access shouldn't depend on parental controls being set correctly.

For many families, the practical path is this. Start with an app on a tablet, show success and medical necessity, then pursue insurance funding for a dedicated device if the funding works out. This is not the only path, but it's the most common one.

What role does an SLP play after the device is set up?

Getting the device is the beginning, not the finish line.

An SLP with AAC expertise should program the device vocabulary to match the child's communication environments, train caregivers and teachers in aided language input, monitor progress and adjust vocabulary as the child's needs change, and troubleshoot access issues as motor skills develop or change.

Many families hit a real problem here: their child's school SLP or private therapist has general training but limited AAC-specific experience. This is common and not a criticism; AAC is a subspecialty. If you feel like your SLP is learning alongside your child, ask them directly whether they have AAC-specific training and whether a referral to an AAC specialist for a co-consult makes sense. Most good clinicians will welcome the question.

For children in schools, the IEP team should include AAC goals if the device is part of the child's educational plan. Goals should be specific and measurable: not "will use device to communicate" but "will use device to make requests across three different environments with 80% accuracy."

Online therapy has expanded AAC access for families in rural areas or where local AAC specialists are scarce. Online speech therapy platforms increasingly include SLPs with AAC certification who can run device trials over video and support families remotely.

The research on caregiver-implemented AAC intervention is actually quite good. A study by Kashinath, Woods, and Goldstein found that parents trained in milieu teaching strategies significantly increased their children's use of AAC in natural environments ^[12]. Parent training is not optional. It's the mechanism of generalization.

Frequently asked questions

What is the difference between high tech and low tech AAC devices?

Low tech AAC devices (picture boards, PECS binders, alphabet charts) require no power, cost very little, and never malfunction. High tech AAC devices are electronic, produce voice output, store large vocabularies, and can adapt to different access methods like touch, switch, or eye gaze. Most experienced AAC users use both depending on the context. Low tech is not inferior; it's complementary.

What is the most common high tech AAC device for children with autism?

There's no single answer because the right device depends on the individual child's motor skills, vocabulary needs, and learning style. That said, Proloquo2Go on iPad and Tobii Dynavox's Snap Core First are among the most frequently prescribed for autistic children in the United States. An AAC evaluation by an SLP is the only reliable way to identify the best fit for a specific child.

At what age can a child start using a high tech AAC device?

There is no minimum age. ASHA's position is that there are no prerequisite cognitive or language skills required before introducing AAC. Children as young as 12 to 18 months have been introduced to AAC systems when communication delays are identified early. Earlier introduction generally leads to better long-term outcomes. If a pediatrician or SLP raises AAC, the answer is not to wait.

Will insurance cover a high tech AAC device for my child?

Medicaid covers dedicated speech-generating devices in all 50 states when a physician documents medical necessity and an SLP evaluation supports the request. Private insurance coverage varies by plan, but many plans cover SGDs as durable medical equipment under the ACA's essential health benefits. App-based systems on consumer tablets are harder to fund through insurance; dedicated hardware has cleaner coverage pathways.

How do I get an AAC evaluation for my child?

Ask your child's pediatrician for a referral to an SLP with AAC expertise, or search ASHA's Find a Professional directory filtering for AAC as a specialty. If your child has an IEP, you can request an AAC evaluation through the school district at no cost under IDEA. Many AAC device manufacturers also have regional consultants who can help connect families with evaluators and arrange device trials.

Can a child use AAC and still learn to speak?

Yes. A 2006 meta-analysis of 23 studies found that 89% of AAC users showed speech that either increased or stayed the same after AAC was introduced; none showed meaningful speech reduction. AAC does not prevent speech development. For many children, having a reliable communication system reduces frustration and increases motivation to attempt speech.

What is a speech-generating device (SGD)?

A speech-generating device is a dedicated electronic AAC device whose primary function is producing voice output to support communication. SGDs are purpose-built hardware, distinct from consumer tablets, and qualify as durable medical equipment for insurance and Medicaid funding purposes. They range from touch-access devices around $5,000 to eye-gaze systems costing $10,000, $15,000 before insurance.

What is eye-gaze AAC and who is it for?

Eye-gaze AAC uses a camera and infrared sensors to track where a user is looking on the screen, selecting symbols or letters without any hand movement. It's designed for people with significant motor limitations who cannot reliably touch a screen or use a switch. Tobii is the leading manufacturer. Eye-gaze systems are among the most expensive AAC devices but are often fully covered by Medicaid as medically necessary equipment.

What is LAMP and why do SLPs recommend it for apraxia?

LAMP stands for Language Acquisition through Motor Planning. It's an AAC approach where every word is always activated by the same motor pattern, building muscle memory for symbol selection. This mirrors how the brain organizes speech motor sequences, which is why SLPs often recommend LAMP-based apps like LAMP Words for Life for children with childhood apraxia of speech. Consistent motor patterns support both device use and natural speech development.

Can a school district provide a high tech AAC device?

Under IDEA, school districts must provide assistive technology, including AAC devices, if the IEP team determines it's necessary for a child to access their education. However, school-provided devices are for educational purposes and typically stay at school. Personally owned devices obtained through Medicaid or private insurance go everywhere. Many families pursue school-provided and personally owned devices simultaneously.

How much does Proloquo2Go cost?

Proloquo2Go costs approximately $299.99 on the Apple App Store as of 2024. It requires an iPad or iPhone, which adds $349 and up for current hardware. Some insurance plans cover the app cost when it's part of a documented AAC plan; most will not cover the iPad itself as durable medical equipment. AssistiveWare, the maker, offers funding support resources on their website.

What funding sources help pay for AAC devices when insurance denies coverage?

Options include state assistive technology programs (every state has one under the AT Act of 2004), the AAC Institute, United Healthcare Children's Foundation, Variety the Children's Charity, and manufacturer hardship pricing. The EPSDT benefit through Medicaid covers medically necessary devices for children under 21 even when standard plan coverage has gaps. Many manufacturers also have refurbished or loaned device programs.

Does my child need to be nonverbal to qualify for an AAC device?

No. AAC is for anyone whose natural speech isn't meeting their communication needs across all environments, all the time. A child who can say some words but cannot reliably make requests, answer questions, or communicate in noisy environments is a candidate for AAC evaluation. ASHA is explicit that AAC supplements speech; it is not reserved for children who are completely nonverbal.

What is the difference between a core vocabulary and a fringe vocabulary on an AAC device?

Core vocabulary is a small set of high-frequency words (go, want, more, stop, I, you, help) that account for roughly 80% of what people say in daily life. Fringe vocabulary is topic-specific (names, preferred foods, school subjects). Effective AAC systems organize both: core words in a consistent location for fast access, fringe words in category folders. Most modern AAC apps support this structure.
