The Problem

After a stroke, the words don't come out right.

Aphasia damages the part of the brain that turns thoughts into language. The mind is still sharp. The thoughts are still there. The words just come out wrong, broken, or not at all.

A person with aphasia might say "fork" when they mean "spoon." They might say a non-word like "blurk" when they mean "phone." They might know exactly what they want but only manage three fragments before they give up.

Their family stops asking. Friends visit less. The person stops trying.

Features

Everything you need.
Nothing you don't.

🚦

FAST Check — Stroke Triage

3-step guided assessment (Face droop, Arm drift, Speech slurring) with live MediaPipe face-tracking and one-Euro smoothing. Practice mode for caregivers, disclaimer gating, and triage history on the Dashboard.

🧠

AI Speech Reconstruction

Whisper transcription → context-aware GPT-4o reconstruction → confidence tiering. Inline 'Did you mean…' alternatives, each tappable to speak. 80% accuracy on aphasic utterances in 2025 peer-reviewed research.

🔊

Speak-This Playback Chain

Reconstructed sentences play back in your own voice. Pipeline: ElevenLabs cloned voice → OpenAI TTS → on-device expo-speech fallback. Voice cloning from recorded samples — no specialist hardware required.

🙂

Selfi — Face-Tracking Exercises

Calibration captures your baseline jaw, lip, and symmetry geometry. Four exercises: Open Vowel (AH), Spread Vowel (EE), Round Vowel (OO), Smile Hold. Live overlay, rep counting, symmetry score per session.

📖

Read Aloud — Read Anything

Paste text, open a PDF, scan paper, or import an email — the app reads it back word-by-word, karaoke-style, at a calm pace with pauses at commas. Tap any word to replay, loop a sentence, or get plain-language simplification. Built for reading fatigue, zero-pressure and one-tap.

🗣️

Speak It For Me

Type or tap a phrase and the phone says it aloud for you — at the doctor, the counter, or on a call. Emotional tone selection (calm, confident, friendly, professional), discreet earbud playback, auto-repeat, and quick-access emergency phrases. Speaks in your cloned voice.

💬

Quick Phrases Library

Pre-built phrases across 8 categories: greetings, basic needs, medical, emotions, daily, social, emergency, and custom. Fully editable. One-tap playback in your cloned voice — even offline.

🏠

Dashboard & Progress

Time-of-day greeting, daily conversation goal + progress bar, FAST status chip, stat tiles (total sessions, 7-day avg confidence, Selfi count), AI Coach tip card, and recent activity feed.

👨‍⚕️

SLP Therapist Portal

Your speech-language pathologist assigns exercises remotely, tracks jaw-opening trends, symmetry scores, session attendance, and reviews shared recordings — no extra appointment needed.

👤

Patient Profile & Context

Aphasia type, severity, daily routine, family members, home layout, and communication preferences power the reconstruction engine. The more context the AI has, the more accurate it gets.

🔒

Privacy & Security

All face processing is on-device. Supabase auth, MMKV-backed local stores, SecureStore for API keys. Audio encrypted at rest and in transit. HIPAA compliant. No ads, no data sales.

How It Works

Speak however you can.
We figure out the rest.

01

Listen

Tap the microphone and speak. The app records whatever comes out, even if it's broken or full of wrong words.

02

Reconstruct

The AI takes what you said and combines it with what it knows about you, your family, and your daily life to figure out what you meant.

03

Speak

The app reads the reconstructed sentence aloud in a clear voice. With voice cloning, that voice can be your own.

Built on GPT-4o, which scored 80% accuracy on aphasia speech reconstruction in a 2025 peer-reviewed study in Scientific Reports.

"Please call my wife on the phone now."

Daily request

Patient said

"want blurk... cold... kitchen... thing"

Evidence Base

Built on clinical research.
Not guesswork.

AphaSay's exercise content, scoring methods, and feedback system are grounded in published speech-language pathology research.

🧬

Neuroplasticity & frequency

Neuroplastic recovery responds to practice frequency over intensity — supporting our daily short-session model over weekly marathon sessions.

Bhogal et al., Archives of Physical Medicine and Rehabilitation, 2003

🎙️

Motor speech feedback loops

Real-time visual and auditory feedback during speech exercises improves motor learning retention. AphaSay provides both — camera overlay and audio scoring — on every rep.

Maas et al., Journal of Speech, Language, and Hearing Research, 2008

📐

Facial symmetry as recovery marker

Facial symmetry measurements correlate with post-stroke motor recovery progression. AphaSay tracks this automatically across every session.

Henkelmann et al., Frontiers in Neurology, 2020

🤖

AI reconstruction of aphasic speech

La Trobe University's 2025 study showed GPT-4o correctly reconstructed 80% of aphasic utterances from AphasiaBank data — the research foundation for AphaSay's Talk mode.
