Every phoneme. Every session. Not whether you passed — which sounds, and exactly how far.

What HEXI sees
/œ/ is costing
you your ring.
Not your pronunciation. That specific sound. We surface it, drill it, and track it until the ring moves.
The workouts
Three modes. One dimension.
01 · Target → Score → Fix
Phoneme Focus
Your weakest sounds, isolated and drilled. Azure scores every attempt at the phoneme, word, and sentence level.
"The gap isn't your accent. It's three sounds you've been rounding off."
02 · Listen → Echo → Match
Shadow & Echo
Hear it once. Text hidden. Echo it back against the dialect model. No transcript. No mercy.
"Pronunciation has a body. Train yours to listen first."
03 · Pressure → Speak → Score
Scenario Voice
A real situation. Communicative load. Pronunciation scored inside the flow of meaning — not in isolation.
"The café doesn't wait for you to feel ready."
The research
Built on what actually works.
Schmidt (1990)
Noticing Hypothesis
You cannot acquire a sound you have never consciously noticed deviating. Imprint™ makes deviation visible at the phoneme level.
DeKeyser (2007)
Skill Acquisition
Declarative knowledge becomes automatic through deliberate proceduralization. Know-about becomes can-produce.
Flege (1995)
Speech Learning Model
Adults form new phoneme categories with perceptually distinct, repeated exposure. Dialect specificity is the mechanism.
Under the hood
The technology behind your score.
UUS Score
Phoneme deviation from your dialect target. Not a pass rate — a precision map.
Azure Speech
Phoneme, word, and sentence granularity. Prosody and intonation on every utterance.
Dialect models
Québécois ≠ Parisian. Colombian ≠ Castilian. Scored against the dialect you're training.
HEXI priority
Weakest phonemes surface first, every session. The ring fills as deviation shrinks.
Your next session

14 days. Your phonemes. No approximations.
