SpeechSprout — Gamified AI Speech Therapy Practice for Kids Aged 4-10
In-person speech therapy costs $150 per session and has 6-month waitlists — parents are left with flashcards and YouTube videos. SpeechSprout delivers gamified phoneme drills in the browser, listens via the Web Speech API, scores pronunciation in real time, and gives parents a weekly progress dashboard to share with their therapist.

Traditional speech therapy for children is expensive and has months-long waitlists, leaving parents with no structured daily practice tool between sessions.
What is it?
Speech therapy for kids is chronically under-supplied: 1 in 12 US children has a speech disorder and therapist waitlists average 4-6 months. SpeechSprout fills the practice gap between sessions with browser-based games that target specific phoneme errors, use the Web Speech API for real-time pronunciation feedback, and reward progress with animated characters. Parents see a weekly report showing accuracy trends per sound. This is not a replacement for therapy — it is the daily practice tool therapists wish existed. Buildable in 3 weeks using Web Speech API (no third-party STT cost), React game components, and Supabase for progress tracking.
Why now?
Speech therapy waitlists hit record highs post-pandemic and have not recovered. Web Speech API browser support reached 93% on Chrome and Edge in the past two years, making browser-based pronunciation scoring finally reliable without a paid STT API.
- ▸Browser-based phoneme games using Web Speech API for live pronunciation scoring.
- ▸Animated reward characters that level up as accuracy improves.
- ▸Parent dashboard showing weekly accuracy trends per target sound.
- ▸Therapist share link that exports a formatted progress PDF.
Target Audience
Parents of children aged 4-10 with diagnosed or suspected speech delays, approx. 4M households in the US actively seeking supplemental practice tools.
Example Use Case
Jordan's 6-year-old son has an R-sound lisp and an 8-month therapy waitlist. She uses SpeechSprout for 10 minutes daily, tracks his accuracy climbing from 40% to 75% over 6 weeks, and shares the PDF report when they finally get a therapist appointment.
User Stories
- ▸As a parent of a child with an R-sound delay, I want daily gamified practice drills, so that my child improves between therapy sessions.
- ▸As a speech-language pathologist, I want to see a parent-shared accuracy report, so that I can assess home practice progress before the appointment.
- ▸As a parent, I want a weekly email showing my child accuracy trend, so that I can tell if the practice is actually working.
Done When
- ✓Game session: done when child speaks a target word and sees a pass or try-again animation within 1 second of speaking.
- ✓Progress dashboard: done when parent logs in and sees a chart of accuracy per phoneme across the last 7 sessions.
- ✓Paywall: done when free user hits 3 phoneme limit and is redirected to Stripe checkout that completes and unlocks all sounds.
- ✓PDF export: done when parent clicks Share with Therapist and downloads a one-page PDF with child name, date range, and per-sound accuracy scores.

How do you build it?
Tech Stack
Next.js, Web Speech API, Supabase, Stripe, Resend — build with Lovable for game UI, Cursor for progress logic, v0 for parent dashboard.
Suggested Frameworks
Next.js App Router, Web Speech API, Framer Motion for animations
Time to Ship
3 weeks
Required Skills
React game component design, Web Speech API integration, Supabase auth and storage.
Resources
MDN Web Speech API docs, Supabase quickstart, Framer Motion docs.
MVP Scope
app/page.tsx (landing), app/play/[sound]/page.tsx (game session), app/dashboard/page.tsx (parent progress), app/api/session/route.ts (save session results), lib/phonemes.ts (phoneme drill config), lib/speech.ts (Web Speech API wrapper), components/GameCard.tsx (animated drill UI), components/ProgressChart.tsx (accuracy chart), lib/db/schema.ts (Drizzle schema), seed.ts (phoneme sets), .env.example.
Core User Journey
Parent signs up -> selects child age and target sound -> child plays drill game -> parent sees accuracy score -> upgrades for weekly report.
Architecture Pattern
Parent creates account -> selects target phoneme -> kid plays game in browser -> Web Speech API scores pronunciation -> session results stored in Supabase -> parent dashboard aggregates weekly accuracy -> PDF export generated on demand.
Data Model
Parent has many Children. Child has many Sessions. Session has many Attempts. Attempt has phoneme target, recorded text, and accuracy score.
Integration Points
Web Speech API for pronunciation detection, Supabase for auth and progress data, Stripe for billing, Resend for weekly progress emails, Vercel for hosting.
V1 Scope Boundaries
V1 excludes: therapist-facing portal, mobile app, multilingual phoneme packs, video sessions, insurance billing.
Success Definition
A parent with no founder contact finds SpeechSprout via Google, creates an account, completes a session with their child, and upgrades to paid within 7 days.
Challenges
Web Speech API accuracy varies significantly across browsers and microphone quality — Chrome on desktop is reliable, Safari and mobile are inconsistent. Distribution reality: parenting Facebook groups and Reddit r/speechtherapy are the fastest channels but require genuine community trust, not spam.
Avoid These Pitfalls
Do not rely on Web Speech API on iOS Safari — gate Chrome-only in v1 and display a browser warning. Do not make medical efficacy claims or you will trigger App Store review and FTC scrutiny. First 10 paying parents will require 3x more time to acquire than building the product.
Security Requirements
Supabase Auth with magic link. COPPA-compliant parent-owned child data with RLS. No child PII stored beyond session accuracy scores. GDPR deletion endpoint required.
Infrastructure Plan
Vercel for Next.js, Supabase for Postgres and auth, Vercel CDN for static game assets, GitHub Actions for CI, Sentry for errors.
Performance Targets
200 DAU at launch. Speech recognition response under 800ms. Page load under 1.5s. Game frame rate 60fps on mid-range Chromebook.

First Run Experience
On first run: a demo child profile named Alex is pre-loaded with 3 completed sessions showing 65% accuracy on the S-sound. User can immediately click Play Demo to try a live phoneme drill without creating an account. No manual config required: Web Speech API activates on click with browser microphone prompt.
How to build it, step by step
1. Define Drizzle schema: Parent, Child, Session, Attempt with accuracy score and phoneme target fields. 2. Scaffold Next.js app with Supabase Auth using magic link for parent login. 3. Build lib/phonemes.ts with 10 phoneme drill configs including target words and example sentences. 4. Build lib/speech.ts wrapping Web Speech API with a promise-based recognition function. 5. Build GameCard.tsx showing animated word prompt and listening indicator with Framer Motion. 6. Build /app/play/[sound]/page.tsx wiring speech recognition to GameCard and posting results to /api/session. 7. Build ProgressChart.tsx using Recharts to show weekly accuracy per sound in parent dashboard. 8. Add PDF export using react-pdf generating a one-page accuracy report. 9. Integrate Stripe Checkout for $9.99/month tier gated behind free phoneme limit. 10. Verify: complete a full parent signup, run a child game session, check that accuracy appears in the dashboard, and confirm Stripe checkout completes.
