The letters that change everything

A Augmentative
A and Alternative
C Communication

Augmentative means adding to someone's existing speech. If a person can say some words but not all, AAC fills in the gaps.


Alternative means replacing speech entirely. For people who cannot produce speech, AAC becomes their primary voice.


Communication is the goal. Not speech for speech's sake, but the ability to express needs, share feelings, ask questions, tell jokes, and participate in life.


AAC includes everything from simple gestures and pointing to picture boards, sign language, and high-tech devices that generate speech at the tap of a finger. There is no one-size-fits-all AAC solution — what works best depends on the individual.

AAC by the numbers

📊
2 million+ Americans cannot rely on natural speech for daily communication
👶
1 in 36 children are diagnosed with autism spectrum disorder; roughly 25-30% are minimally verbal
🧠
795,000 Americans have a stroke each year; about 1 in 3 experience aphasia (language loss)
🏥
25% of ICU patients cannot communicate their needs to medical staff
🌎
65+ million people worldwide could benefit from AAC but lack access

AAC is for anyone who needs it

There are no prerequisites for AAC. You don't need to "fail" at speech first. If someone has difficulty communicating, AAC can help — at any age, with any condition.

🧩

Autism Spectrum Disorder

Approximately 25-30% of autistic individuals are minimally verbal or nonverbal. AAC provides visual-first communication that aligns with how many autistic people process information. Early AAC access improves language outcomes.

🧠

Stroke & Aphasia

Stroke can suddenly rob a person of speech while leaving cognition intact. AAC bridges the gap during recovery, allowing stroke survivors to express needs, participate in therapy, and maintain relationships. Many types of aphasia respond well to AAC.

👶

Developmental Delays

Children with Down syndrome, apraxia of speech, intellectual disabilities, and other developmental conditions benefit from AAC during critical language-learning windows. AAC supports language development rather than replacing it.

Families →

ALS & Progressive Conditions

Amyotrophic lateral sclerosis (ALS), Parkinson's disease, and multiple sclerosis can progressively affect speech. AAC provides continuity of communication as abilities change, with tools that adapt to decreasing motor function over time.

Medical AAC →
🩹

Traumatic Brain Injury

TBI can affect speech, language processing, or both. AAC helps during acute recovery in hospital settings and supports long-term rehabilitation. Many TBI survivors use AAC temporarily during recovery before regaining speech.

From gestures to speech-generating devices

AAC exists on a spectrum from low-tech to high-tech. Many people use multiple types depending on the situation. The best AAC system is the one that gets used.

No-Tech

Unaided AAC

Communication using only the body — no external tools. This is the most natural form of AAC and is used by everyone, even fluent speakers.

Gestures Facial expressions Sign language Body language Eye gaze
Low-Tech
📄

Paper-Based AAC

Physical boards, books, and cards with pictures, symbols, or text. Durable, no batteries needed, and inexpensive. Great as a backup to high-tech systems.

Picture boards PECS cards Communication books Letter boards Choice boards

Tap. Build. Speak.

Modern AAC devices like TinkySpeak are intuitive. Here's how picture-based AAC works in practice.

1
👁

See & Recognize

The user looks at a grid of picture tiles organized by category — feelings, needs, food, people, places, actions. Each tile has an image and a word label.

2
🖐

Tap to Select

The user taps the pictures that represent what they want to say. Tiles appear in a sentence strip at the top of the screen, building a phrase word by word.

3
🗨

Device Speaks

The user hits "Speak" and the device reads the sentence aloud in a natural voice. The listener hears clear speech. Communication happens. Connection is made.

4
🔄

Learn & Grow

Over time, users learn the board layout, build speed, and access more vocabulary. Many progress from single-word selections to full multi-word sentences.

Myths vs. facts about AAC

Misunderstandings about AAC can delay access to communication. Here's what the research actually shows.

Myth
"AAC will prevent my child from learning to talk."
Fact
Research consistently shows AAC does not hinder speech development. A 2006 meta-analysis by Millar, Light, and Schlosser found AAC either had no effect on or increased natural speech production. AAC gives individuals a way to communicate while speech develops.
Myth
"You should wait and see if speech develops before trying AAC."
Fact
There is no evidence supporting a "wait and see" approach. ASHA (American Speech-Language-Hearing Association) recommends early AAC access. Every day without communication is a day without learning, connection, and self-expression.
Myth
"AAC is only for people who can't speak at all."
Fact
AAC is for anyone who has difficulty communicating through speech alone. Many AAC users can say some words but use AAC to augment their speech — filling in gaps, expressing complex ideas, or communicating when stressed or tired.
Myth
"A person needs certain cognitive skills before they're ready for AAC."
Fact
There are no prerequisites for AAC. The old idea of "candidacy" has been thoroughly debunked. You don't need to demonstrate intent, cognitive ability, or physical skills first. Everyone communicates, and everyone deserves a way to do it.
Myth
"AAC devices are just for kids."
Fact
AAC is used across the entire lifespan. Adults with stroke, ALS, Parkinson's, TBI, and many other conditions use AAC. Hospitals use AAC for intubated patients. Communication needs don't have an age limit.
Myth
"AAC is too complicated for my child / patient / student."
Fact
Modern AAC can be as simple as tapping a single picture. Devices like TinkySpeak come pre-loaded and ready to use. You can start with a few tiles and add more as the user grows. The technology adapts to the user, not the other way around.

Key terms explained

New to AAC? Here are the essential terms you'll encounter.

AAC (Augmentative and Alternative Communication)
Any method of communication used to supplement or replace speech, ranging from gestures to high-tech speech-generating devices.
SGD (Speech-Generating Device)
An electronic device that produces spoken output when the user selects symbols, pictures, or text. Also called a "voice output communication aid" (VOCA).
SLP (Speech-Language Pathologist)
A healthcare professional who evaluates and treats communication disorders. SLPs assess AAC needs and help individuals learn to use AAC systems.
Aphasia
A language disorder caused by brain damage (usually from stroke) that affects the ability to speak, understand, read, or write. Does not affect intelligence.
PECS (Picture Exchange Communication System)
A specific low-tech AAC method where users exchange physical picture cards to communicate. Developed by Bondy and Frost in 1985.
Core Vocabulary
The small set of words (approximately 200-400) that make up 80% of what we say daily. Words like "want," "go," "more," "help," "not," "I," "you."
Fringe Vocabulary
Specific nouns, names, and context-dependent words that are unique to an individual. Words like "pizza," "grandma," "playground."
Modeling
The practice of using AAC alongside the person learning it. When you tap tiles on the AAC device while talking, you're modeling — and it's the most effective way to teach AAC.
SETT Framework
A decision-making framework for selecting assistive technology: Student (who?), Environment (where?), Tasks (what?), Tools (how?). Used by SLPs and educators.

DME (Durable Medical Equipment)
The insurance classification for AAC devices. Classifying a speech-generating device as DME is what allows insurance and Medicaid to cover the cost.

Everything you need to know

What does AAC stand for?

AAC stands for Augmentative and Alternative Communication. "Augmentative" means adding to existing speech. "Alternative" means replacing speech entirely. AAC encompasses any method of communication beyond natural speech, from simple gestures and picture boards to high-tech speech-generating devices.

Will AAC prevent my child from learning to talk?

No. Research consistently shows that AAC does not hinder speech development and often supports it. A 2006 meta-analysis by Millar, Light, and Schlosser found that AAC intervention either had no effect on or actually increased natural speech production. AAC gives individuals a way to communicate while speech develops.

Who benefits from AAC?

AAC benefits anyone who has difficulty communicating through speech alone. This includes individuals with autism, stroke survivors with aphasia, people with ALS, cerebral palsy, Down syndrome, traumatic brain injury, and many other conditions. AAC is also used temporarily by patients in hospitals who are intubated or recovering from surgery.

How much does an AAC device cost?

Traditional dedicated AAC devices can cost $5,000 to $15,000+. AAC apps typically range from $100 to $400 per year. TinkySpeak offers a pre-loaded AAC tablet for $125 one-time with no subscription, making it one of the most affordable high-tech AAC options available.

Is AAC covered by insurance?

Many insurance plans, including Medicaid, cover AAC devices as "durable medical equipment" when prescribed by a speech-language pathologist. Medicare covers speech-generating devices. School districts are also required to provide AAC under IDEA if included in a student's IEP. The process can take months, which is why affordable options like TinkySpeak are valuable as an immediate solution.

At what age should AAC be introduced?

There is no minimum age for AAC. Research supports early intervention, and many children begin using AAC between 12 and 24 months. The American Speech-Language-Hearing Association (ASHA) states there are no prerequisites for AAC — you don't need to "fail" at speech first.

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

Low-tech AAC includes non-electronic tools like picture boards, communication books, and letter boards. High-tech AAC includes electronic devices and apps that generate speech, like TinkySpeak. Many people use a combination of both, and there is no one-size-fits-all solution.

How do I get started with AAC?

You can get started immediately with TinkySpeak for $125 — no evaluation, prescription, or waitlist needed. For a comprehensive approach, consult a speech-language pathologist (SLP) for an AAC evaluation. Your child's school can also request an assistive technology evaluation as part of the IEP process. Many families start with a device like TinkySpeak while pursuing formal evaluation.
