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

Last updated 2026-07-11

What does 'two-word combination' mean in AAC, and why does it matter?

A two-word combination is two separate symbols or words put together to make a new meaning. 'Want cookie' says something neither word says alone. 'More swing' means something different from 'more bubbles.' That combinatorial leap matters developmentally, because it shows a child is starting to build language instead of just labeling things.

For a late talker, moving from single words to combinations is often the door to faster vocabulary growth. The American Speech-Language-Hearing Association notes that most typically developing children begin combining words between 18 and 24 months ^[1]. For kids using AAC, that same milestone is reachable, just on a different timeline and through a different physical route.

AAC (augmentative and alternative communication) covers any system that helps someone communicate beyond natural speech: picture boards, speech-generating apps, high-tech devices. The research is clear that AAC does not slow speech development and often supports it ^[2]. So teaching two-word combinations on a device is not a consolation prize. It is real language learning.

What is aided language input, and is it really the best approach?

Aided language input (also called aided language modeling) means you, the communication partner, point to or activate symbols on the AAC system while you talk. You model language on the child's own tool instead of speaking into the air.

Yes, it really is the best approach for building symbol combination. A 2012 study by Drager and colleagues in the American Journal of Speech-Language Pathology found that children with complex communication needs showed significantly more symbol use after aided language input compared to instruction without modeling ^[3]. A 2021 systematic review in the Journal of Speech, Language, and Hearing Research confirmed that naturalistic AAC intervention, which puts aided modeling at the center, produced positive outcomes across age groups and AAC types ^[4].

The logic holds up. You wouldn't teach a child piano by talking about piano. You'd play alongside them. Aided language input works the same way. You show the child what their tool can do, in real moments, over and over.

The hard part for parents is actually doing it. Talking and pointing at the same time takes practice, especially on a dynamic display where symbols live on different pages. Start with just two or three target combinations per week so you're not hunting around the device while your child waits.

How do you pick the right two-word combinations to target first?

Pick combinations your child is already motivated to say. Not the ones a worksheet thinks are important. If your kid loves the swing, 'go swing' beats 'more cracker' even if crackers are developmentally textbook.

A useful framework is to combine words from two different categories: an action word plus a noun, or a modifier plus a noun. The most common first combinations in typical development look like this:

Keep the target list short. Most speech therapy approaches for AAC work on three to five core combinations at a time, building repetition across the day rather than breadth across a huge word bank ^[5].

Check that both words in the combination are already on the device. If your child has to hop to page 3 for 'more' and back to page 1 for 'cookie,' the motor demand will swamp the language goal. Reorganize if needed, or work with your SLP on a core vocabulary layout that puts high-frequency words one tap away.

What does a typical practice session actually look like at home?

Forget the word 'session.' The goal is to weave modeling into what you're already doing, because that's when children learn language best: in context, with real emotional stakes, repeated many times.

Here's a concrete example using snack time and the target 'want more.'

Give a small amount of a preferred food. When your child reaches, looks at you, or vocalizes, you say 'want more?' while you touch 'want' and then 'more' on the device. Then hand over the food. Don't make them repeat it back. Don't withhold food as a bargaining chip, because that creates stress, not communication. Model, respond, repeat.

Over many days and many repetitions, you add an expectant pause before you hand over the food. You look at the device. You wait five to ten seconds. If the child touches either symbol, celebrate it. If they touch both in any order, that's a combination attempt and it counts.

You can run this pattern across half a dozen daily routines: getting dressed ('shoes on'), bath time ('more bubbles'), outdoor play ('go fast'), reading ('turn page'). The research on naturalistic developmental behavioral intervention suggests distributed practice across multiple daily routines works better than massed drill ^[4].

Aim for roughly 20 to 30 modeling opportunities per target per day, spread across routines. That sounds like a lot until you realize a five-minute snack can hold eight opportunities if you serve tiny portions.

How long does it take for a child to start combining words on AAC?

Every parent asks this, and the honest answer is that it varies a lot and nobody has tight population-level data on a clean timeline.

The research suggests children typically need to observe a combination modeled in context somewhere between 50 and 200 times before attempting it on their own ^[3][5]. If you're hitting 20 to 30 modeling opportunities a day across routines, that's roughly 5 to 10 days of work per target before a first spontaneous attempt might show up. But some kids take weeks. Some take a month. A few surprise you on day three.

Things that move the timeline: the child's current language level, how consistently the AAC system is available, how motivated they are by the specific vocabulary targets, and whether they have a motor-planning challenge like childhood apraxia of speech that makes device navigation harder.

If after six to eight weeks of consistent daily practice across multiple routines a child still isn't attempting combinations, bring your data to your SLP and talk about whether the device layout, the vocabulary targets, or the modeling strategy needs to change. Don't just wait longer.

What is the 'wait time' strategy and how do you use it without frustrating your child?

Wait time is exactly what it sounds like. You pause after modeling, look at the device or your child expectantly, and give them room to respond before you jump in. Speech-language pathologists often recommend five to ten seconds of silence, which feels agonizingly long in real life.

It works because children with language delays often need more processing time than typical children, and adults have a strong instinct to fill silence by repeating themselves, restating the question, or just handing over the thing the child wanted. All of that short-circuits the child's attempt.

To do it without causing frustration, make sure the child is regulated first. If they're already upset, wait time tips into meltdown. Pick calm, motivated moments. Get physically close, make eye contact, and look at the device together. If the child reaches for something without touching the device, gently redirect: 'can you tell me? I see the button right here.' Then wait again. If they touch one symbol, prompt 'what do you want more of?' and point to the 'more' symbol, modeling the second word yourself.

The goal isn't to withhold. The goal is to create a reason to communicate. There's a difference.

Should you use errorless learning or prompting with a hierarchy?

Both can work, and your SLP should guide which fits your child. Here's the practical difference.

Errorless learning means you provide so much support up front that the child almost can't fail. You model the combination, guide their hand to the symbols, and give the reward. The error rate stays near zero. This works well for children who get very distressed by mistakes, or for kids who are just learning that the device does something.

A prompting hierarchy starts with the most natural prompt (expectant waiting) and only escalates if the child doesn't respond: wait, then indirect verbal ('tell me what you want'), then direct verbal ('say more juice'), then point, then physical guidance. The goal is to use the least support necessary so the child has room to initiate.

For two-word combination goals specifically, a time-delay procedure has good research support ^[5]. You start by modeling the combination with zero delay (no expectation of imitation), then gradually introduce a pause. After a few weeks you add three seconds of delay, then five, then more. The child learns that the pause is their cue to try.

If your child also shows patterns of echolalia, a prompting hierarchy can sometimes produce more echolalic responses than genuine communication. Errorless learning paired with natural environment teaching tends to produce more functional communication in those cases.

Which AAC systems are best for teaching two-word combinations?

The best system is the one your child will actually use, that has enough vocabulary to combine, and that your family can learn quickly.

For two-word combination goals, the device needs at minimum: a full core vocabulary (the 200 to 400 most common words used across contexts), easy access to action words and modifiers, and a layout your child can navigate without too many page turns per combination.

High-tech options like Proloquo2Go, TouchChat, and Snap Core First are built around core vocabulary and allow customization. Low-tech options like a PECS binder or a paper core board can also support combination, because a child can pick up two cards and hand them over together.

You can read a detailed breakdown of device options in our guide to AAC devices.

One thing to watch: some apps marketed to parents are really vocabulary-drill tools, not communication systems. They let kids label pictures but don't give them the action words and modifiers they need to combine. Before choosing an app, check whether it puts words like 'want,' 'more,' 'go,' 'stop,' 'big,' 'my,' and 'help' on a home screen or near-home screen. If you have to navigate three pages to find 'go,' the combination 'go outside' is going to be very hard to use spontaneously.

How do you coordinate home practice with your child's speech therapist?

The strongest AAC outcomes happen when home practice and therapy pull in the same direction. That sounds obvious. It's surprisingly rare.

Ask your SLP for three specific things at each appointment: what two or three combinations are the current targets, exactly how to model them on the device (including which pages the words live on), and what data they want you to collect at home.

Data collection doesn't have to be complicated. A tally sheet on the fridge works. Mark each time you model the target combination, and mark each time the child attempts any part of it. After a week, you have real information about whether practice is actually happening and whether the child is moving.

If your child receives early intervention services under IDEA Part C (birth to age three) or school-based services under Part B (ages three to twenty-one), the AAC system and communication goals should appear in the IFSP or IEP. Under IDEA, AAC is treated as a related service, and families have the right to be involved in goal setting ^[6].

If you don't have access to a local SLP right now, online speech therapy has grown a lot and can be a real option for AAC coaching, especially for parents who need guidance on modeling strategy rather than hands-on device work.

What if my child resists using the AAC device or throws it?

This is one of the most common things parents run into, and it's rarely about the device itself. It usually comes down to one of four things: the device is too hard to navigate, the targets aren't motivating, the child is being prompted in a way that feels coercive, or the device only appears at 'therapy time' instead of being available all day.

First, check availability. AAC works best when it's present all the time, like glasses. A device that only comes out for practice becomes a device the child links with work, not with getting what they want.

Second, drop the pressure. Many families accidentally turn AAC into a test ('show me where more is') rather than a tool. If the child links the device with being put on the spot, avoidance makes total sense. Go back to pure modeling with no expectation of response for a week. Just show them what you'd say on the device and move on.

Third, make sure the vocabulary is reachable. If the child throws the device after three seconds, they may be frustrated that they can't find the word they want. A simpler layout with fewer pages often beats a full 60-symbol grid for a child just starting combinations.

If a child is being assessed or already has a diagnosis on the autism spectrum, device resistance sometimes connects to sensory sensitivities (device sounds too loud, screen too bright) or to dysregulation that needs addressing before communication can happen. Your SLP and, if relevant, your OT should know about the resistance.

Are there specific strategies for kids with apraxia who also use AAC?

Yes, and the overlap between apraxia and AAC is an area where parents often get conflicting advice.

Children with apraxia of speech have trouble with the motor planning speech sounds require. AAC can reduce that demand while the motor learning work continues. The two aren't in competition. The American Speech-Language-Hearing Association supports concurrent use of AAC and speech therapy for children with apraxia ^[7].

For two-word combination goals, kids with apraxia may find that combining symbols on a device is actually easier than combining spoken words, because touching two icons is more predictable than coordinating articulation for two words. That can mean combinations emerge sooner on the device than in speech, which is worth celebrating.

The strategy shift for apraxia is to pay attention to the motor teaching on the device too: consistent placement of core words, practicing the same motor sequence repeatedly, and minimizing page navigation that forces re-learning where things are. Many children with childhood apraxia of speech benefit from heavy repetition of the same motor pattern, so drilling a single combination like 'want more' across six routines a day fits neatly with apraxia treatment principles.

Some families use Little Words (littlewords.ai) as an at-home modeling tool between SLP visits, partly because it adapts vocabulary targets based on what the child is working toward. That kind of daily repetition matters.

How do you know if the AAC strategy is working?

Progress in two-word combinations looks different than you might expect. Don't wait for your child to use a combination spontaneously and correctly in a brand new situation. That's the end goal, not the first sign of progress.

Early signs the approach is working: the child touches the device at all when they want something (single symbol), watches your hand when you model on the device, uses one symbol from a target combination (they touch 'more' even though you were targeting 'more juice'), and attempts two symbols in any order.

A simple data system: every day during your target routine, mark whether the child (a) did not engage with the device, (b) touched one symbol, or (c) touched two or more symbols. After two weeks, if you see a trend from a to b, or b to c, the approach is working even if the combination isn't perfect yet.

If you see no change across three or four weeks of consistent practice (20-plus modeling opportunities per day), something needs to change. That might be the vocabulary targets, the device layout, the motivation level of the context, or the underlying language level the goals assume. That's a conversation for your SLP, with your data in hand.

The Vineland Adaptive Behavior Scales and the MacArthur-Bates Communicative Development Inventories are two standardized tools your SLP might use to track communication growth over time ^[8][9]. Both are research-validated and give you a baseline to measure against.

Frequently asked questions

At what age should a child be combining words with AAC?

In typical development, children start combining words around 18 to 24 months ^[1]. For children using AAC, the timeline varies. If a child is past 24 months and using only single symbols or no symbols at all, that's a strong reason to discuss two-word combination goals with an SLP now. AAC intervention tends to work better the earlier it starts, so there's no value in waiting until a child is 'ready.'

Do I need a high-tech device to teach two-word combinations, or can I use a low-tech board?

A low-tech core vocabulary board works well for two-word combination goals. The child can physically pick up or point to two symbols in sequence. Some families start low-tech to build the concept of combining, then move to a high-tech device. The most important feature is that both target words are easy to find, not buried behind multiple pages or symbols.

My child uses single words on AAC but won't try two words. What am I doing wrong?

Probably nothing. The jump from one to two is cognitively significant and takes time. The most common issue is parents starting to expect combinations before modeling enough of them first. Check that you're modeling the two-word combination 20 or more times per day across several routines before expecting the child to try it. Also check that both words are easy to reach on the device layout.

How many words should a late talker have before working on two-word combinations?

Most speech-language pathologists begin two-word combination work when a child has a functional vocabulary of around 50 words, spoken or on AAC. That 50-word threshold matches typical developmental patterns for when word combinations emerge naturally ^[1]. In practice, many SLPs start seeding combination modeling earlier, so the child hears combinations before they're expected to produce them.

Can I teach AAC two-word combinations without a speech therapist?

You can do the daily modeling and routine-based practice yourself, and it matters a great deal. But an SLP should set the goals, choose the device or board layout, and monitor progress. IDEA guarantees school-age children (and, under IDEA Part C, infants and toddlers) access to speech-language services if they qualify ^[6]. If you can't access in-person services, telehealth SLP services are a real option for AAC coaching.

Should I stop trying to get my child to talk and just focus on AAC?

No. AAC and speech development aren't a trade-off. Research consistently shows AAC supports rather than replaces speech development ^[2]. Your SLP should work on both at once: building speech motor skills and building AAC combination use. The goal is for the child to communicate effectively, and most children use a mix of speech and AAC as their skills grow.

What is the difference between PECS and core vocabulary AAC for teaching combinations?

PECS (Picture Exchange Communication System) was originally built around exchanging single pictures for items. It has a Phase IV that introduces sentence strips for combinations, but the vocabulary is largely fringe (specific items) rather than core (flexible, high-frequency words). Core vocabulary AAC gives access to words like 'want,' 'go,' 'more,' and 'stop' that combine across many contexts, which most SLPs now consider a stronger foundation for combination teaching.

My child's IEP doesn't mention AAC. How do I bring it up?

Request an IEP meeting and ask for an AAC evaluation to be part of the discussion. Under IDEA, the team must consider AAC for any child with a communication need ^[6]. Bring documentation: a list of the child's current communication attempts, any SLP reports, and a written request. You don't need to be an expert. You're asking the team to consider whether AAC supports would help your child meet communication goals.

How do I model two-word combinations if I don't know how to use the AAC device well?

Ask your SLP for a 15-minute device tutorial focused only on your target words. You don't need the whole device. Find where 'more,' 'want,' 'go,' 'stop,' 'my,' and five or six high-frequency nouns live, and practice getting to them quickly. Most families get comfortable with three to five two-word targets without mastering the full layout. Start small and grow your own fluency alongside your child's.

Is there research supporting AAC for late talkers specifically (more than autism)?

Yes, though much of the AAC research has historically focused on children with complex communication needs including autism. A 2021 systematic review in the Journal of Speech, Language, and Hearing Research found positive outcomes for naturalistic AAC intervention across diverse populations ^[4]. ASHA's evidence map on AAC includes studies of children with developmental language disorder, Down syndrome, and idiopathic late talking, not only autism.

What does 'full AAC' mean, and does my child need it for combination goals?

A full AAC system carries a large core vocabulary (typically 200-plus words), organized so the child can say almost anything they'd want to, beyond requesting items. For two-word combination goals, you need at least a solid core: action words, modifiers, and pronouns alongside nouns. A system with only 20 to 30 symbols for requesting isn't set up for genuine combination work.

How do I track my child's AAC progress at home between therapy appointments?

Keep a simple daily log: during your target routine, note whether the child (1) didn't engage with the device, (2) used one symbol, or (3) used two or more symbols. Take a 30-second video once or twice a week during a routine. Bring the log and a video clip to each SLP appointment. That's enough data for your therapist to see real trends and adjust the approach if needed.
