1. Little Words
Free trial available, then monthly or yearly subscription (managed in device settings). No ads, no data sold, COPPA compliant.
For outside context, see this asha.org.
This is the only app in the group where the child never touches a menu. Buddy, an AI companion, talks and listens from the first second. No reading required. No typing. A pre-reader who melts down at walls of text can actually use this independently, which is not something I can say about most of the apps below.
What sets it apart mechanically: Buddy remembers the child’s name, favorite topics, and where they left off. That sounds minor until you watch a four-year-old light up because the app called them by name and asked about dinosaurs again. Sessions start with a mood check so Buddy can dial his energy up or down before they even begin. Sensory presets (calm, gentle, high-energy) and adjustable session lengths from 5 to 20 minutes mean the app bends to the child’s regulation state rather than demanding the child perform on cue.
The speech work is real. Target sounds like s, r, l, sh, and th get woven into actual conversation games, “What’s That Sound” and “Voice Maze” among them. Buddy models correct pronunciation without ever marking an answer wrong. No red X. No “try again” tone. Just a natural re-model the way a good clinician does it.
Parents get a dashboard with session history, weekly progress cards, and SLP-style PDF reports that you can hand directly to your child’s therapist. That last point matters. Most apps are an island. Little Words tries to be a bridge.
One honest note worth stating here: no app, this one included, replaces time with a licensed speech-language pathologist. Apps are practice and engagement tools, full stop.

2. Speech Blubs
Over 1,500 activities, voice-controlled, built for kids with apraxia, autism, speech delay, and ADHD. At $59.99 a year it lands in the mid-range for this category. The approach is video-based modeling, meaning kids watch real faces and animated characters and try to mimic sounds. It works well for kids motivated by imitation. It does not adapt in real time the way a conversational AI does, and the structure skews more drill-like than play-based.
3. Articulation Station (Little Bee Speech)
Built by licensed SLPs, and you can tell. More than 1,200 target words, organized by phoneme and word position (initial, medial, final). The Pro version at $59.99 is a one-time purchase, which is genuinely good value for families doing long-term articulation work. It is clinical in the best sense of the word. It is also not particularly warm or adaptive. Think of it as a well-organized therapy workbook that lives on a tablet.
4. Otsimo
Strong choice for non-verbal kids and those with significant support needs. The AI feedback loop and 200+ exercises cover autism, apraxia, and Down syndrome specifically. Annual pricing drops to about $4.49 a month, which is the lowest in this group. The interface is structured and menu-heavy, so younger or pre-reading kids will need a caregiver alongside them.
5. Tactus Therapy
A suite of individual clinical apps priced between $9.99 and $99.99 each. Designed by SLPs for targeted, evidence-informed practice. The breadth of the catalog is impressive. Because each app is purchased separately, the cost can add up fast if a child has multiple goals. Best for families already working with a therapist who can point to the right specific tool.
6. Constant Therapy
Evidence-based and spans a wider age range than most apps here. Good for families managing longer-term speech and language goals. The reporting features are solid. Less focused on the youngest toddler crowd, but worth knowing about as kids age into school years.
7. Hallo
Oriented toward language exposure and conversational practice with AI. More relevant for older kids working on fluency and confidence in a second language or general speaking practice. Not purpose-built for early speech delays or articulation goals.
8. Expressable (In-Person or Teletherapy With a Licensed SLP)
Not an app. The real thing. A licensed speech-language pathologist, whether in-person or via a platform like Expressable, is the only option here that offers actual diagnosis, treatment planning, and clinical judgment. Every other item on this list is a supplement. If there is a real concern about a child’s speech development, a professional evaluation comes first.
9. ASHA Free Resources
The American Speech-Language-Hearing Association publishes free guides, milestone checklists, and activity ideas for parents. No gamification, no app, but credible and genuinely useful for understanding whether a child is developing on track before spending money on anything else.
10. Free Library and Community Apps
Many public libraries offer free access to early literacy and language apps through platforms like Sora or Libby. Quality varies. None are purpose-built for speech practice, but for budget-limited families they are a real starting point alongside caregiver-led talking and reading time, which research consistently shows matters more than any app.
My Bottom Line
For a pre-reader, a sensory-sensitive kid, or a child who shuts down at structured drills, Little Words is the only app here that removes the interface friction entirely and builds practice into actual conversation. Articulation Station wins on clinical depth for school-age articulation goals. Otsimo earns its place for non-verbal and high-support-needs kids at a genuinely low price point. Speech Blubs sits in the middle: decent breadth, moderate cost, limited adaptivity.
None of these replace a therapist. Pick the one that fits the child in front of you.

Common Questions
Does Little Words work for a child who cannot read yet?
Yes, and that is specifically what separates it from most of the competition. Buddy, the AI companion, runs entirely through voice and listening. No menus, no text prompts, no typing required. A two-year-old or a pre-reader with a developmental delay can move through a full session without a caregiver hovering to translate the interface.
Is Speech Blubs actually useful for apraxia, or is that just marketing?
The video-modeling approach does align with principles used in motor-speech therapy, since watching a real mouth form sounds gives kids a target to imitate. That said, Speech Blubs is not clinician-built and does not adapt to a child’s specific motor-speech errors in real time. It is a useful practice supplement for apraxia, not a replacement for a therapist who specializes in childhood apraxia of speech.
When does Articulation Station make more sense than Little Words?
Articulation Station is the better fit for school-age kids who already have a formal articulation goal from an SLP, know which sounds they are targeting, and need organized, high-volume repetition across word positions. Little Words is stronger for younger or sensory-sensitive kids who need low-pressure, conversation-based practice rather than structured drill work.
Can Otsimo be used without a caregiver present for a four-year-old?
Probably not independently. Otsimo’s interface is menu-driven and text-dependent, which means a pre-reading child will need an adult to help work through between activities. The exercises themselves can be done with the child once a caregiver sets up the session, but it is not a solo-use tool the way Little Words is designed to be.
How do any of these apps connect to what a child’s SLP is already working on?
Most do not, honestly. Little Words is the notable exception, generating PDF progress reports formatted for clinical handoff. Tactus Therapy apps are often recommended directly by SLPs because the catalog maps to specific therapy targets. For everything else, the connection between app practice and clinic goals depends entirely on the family sharing information manually with their therapist.
