LUMI Voice
Their words. Their melody.
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Finally understand their scripts — and grow their language without losing the melody. Double-tap to speak.
Their words matter. The melody matters too.
LUMI Voice is a calm talker for gestalt language processors and autistic communicators — built so families can keep the phrases, scripts, and loops that already feel like home, then grow from there without forcing a keyboard AAC grid.
We believe communication starts with what your child already says — not with wiping the slate clean.
WHAT YOUR CHILD SEES
• A simple shelf: Safety, Phrases, Mix pieces, Favorites, and Loops
• Double-tap a tile to speak — that’s the whole child UI
• Short video loops they love (from camera, Photos, or YouTube) that can live next to their words
• Optional interest skins so the play shelves feel like them
IPAD AND IPHONE — SAME CHILD, TWO JOBS
• iPad is the home base — the big talker for the table, couch, or therapy room, with every shelf in view
• iPhone is the companion — pocket AAC when you’re out and about, or when a caregiver needs quick Setup away from the iPad
• Same Apple ID / care circle and the same child: phrases, loops, and mix pieces stay in sync across both
• On iPhone, shelves are one tab at a time (Safety · Phrases · Loops · Mix) with larger tiles so little fingers still work
• Caregiver tools open full-screen on iPhone; on iPad they stay as the familiar hold-to-open panel
• Share to LUMI is especially handy on iPhone — send a clip from Photos or YouTube, trim, and it lands on the shelf
WHAT YOU DO AS THE CAREGIVER
• Hold Caregiver tools (~1.5s) to open setup — optional PIN so little hands stay on the talker
• Record short voice memos in your voice for the phrases your child needs
• Grow new phrases that keep their melody (“More like this”)
• Turn one favorite phrase into Mix pieces they can tap together
• Optional Parent voice: record once (~30s) so new short phrases can sound like you — re-record any tile anytime
• See Intent translations when you want that “oh — that’s what they meant” moment
• Export a language progress PDF when you’re heading to the IEP table
LUMI VOICE PREMIUM (OPTIONAL)
• Safety shelf + basic playback
• Premium is for understanding and growing their language — not for locking the talker
LUMI Voice is from the same team as Moonbow. Same belief: meet your child where they are, protect what’s working, and help the next words feel possible.
Not a medical device. Not a symbol-grid AAC. Not a robot voice replacing your family. Just their words — and room to grow.
