What HEXI scores
Register is
the ceiling.
Not your grammar textbook knowledge. The way you switch — or fail to switch — between formal and informal in real communicative pressure. That specific gap.
The workouts
Three modes. One dimension.
01 · Prompt → Build → Score
Construct™
Isolated grammar target. One structure at a time. HEXI scores accuracy before fluency — you can't automate what you haven't understood.
"You don't speak the language yet. You're assembling it. That's step one."
02 · Situation → Respond → Reflect
Compose™
A real context. A real prompt. No grammar cues — just produce. HEXI analyses what breaks under communicative pressure.
"Grammar you can explain is not grammar you own. Compose™ finds the gap."
03 · Topic → Speak → Score
Think Out Loud
Thirty seconds. Unscripted. HEXI transcribes, analyses density, flags hesitation patterns, and scores register against your dialect target.
"Fluency isn't speed. It's not stopping to think in your first language."
The research
Built on what actually works.
Swain (1985)
Output Hypothesis
Producing language forces learners to notice gaps comprehension conceals. Construct™ makes the gap visible — every attempt.
DeKeyser (1997)
Practice & Automatization
Controlled accuracy becomes automatic through repeated production. Declarative knowledge must be proceduralized through output.
Skehan (1998)
Complexity, Accuracy, Fluency
Under communicative load, learners trade accuracy for fluency. Tracking all three simultaneously separates feedback from guesswork.
Under the hood
The technology behind your score.
Deepgram STT
Every spoken word transcribed. Hesitation markers, false starts, and fillers logged across sessions.
Grammar scoring
Verb agreement, tense, gender, and syntax scored against your target dialect. Québécois grammar is not Parisian.
Register analysis
Formal vs. informal register flagged in real time. HEXI knows whether the situation called for tu or vous.
HEXI compound
Output patterns compound with Ring 2 comprehension data. What you can't hear, you can't produce correctly.
