Real spoken input. Native speed. Not what you understood — which patterns you keep missing, and exactly where.

What HEXI hears
Connected speech
is the ceiling.
Not your vocabulary. Not your grammar. The way native speakers blur words together at speed — that specific gap. We find it, drill it, track it.
The workouts
Three modes. One dimension.
01 · Listen → Recall → Score
Intake™
Native audio. No transcript. No pause button. Answer what you heard. HEXI tracks every gap and closes it next session.
"You don't understand less. You're missing specific patterns. HEXI finds them."
02 · Audio → Shadow → Compare
Shadow Listen
Hear the sentence. Repeat it back in real time — at native speed. The gap between what you said and what was said is your score.
"Listening is a muscle. You've been resting it."
03 · Fragment → Infer → Verify
Context Inference
Partial input. Missing words. You fill the gap from context — the way fluent speakers do every single conversation.
"The native speaker doesn't catch every word. They don't need to."
The research
Built on what actually works.
Krashen (1982)
Input Hypothesis
Acquisition happens through comprehensible input at i+1. Intake™ calibrates difficulty to your real comprehension ceiling.
Nation (2001)
Listening Load
Comprehension breaks at specific vocabulary thresholds. HEXI tracks lexical gaps by dialect, not generic word frequency.
Field (2008)
Listening as skill
Listening is active decoding. Phoneme-to-word mapping, prosodic parsing, and inference are all trainable sub-skills.
Under the hood
The technology behind your score.
Deepgram STT
What you said, transcribed at the word level. Comprehension uses what you heard, not how you said it.
Gap analysis
Missed words mapped against frequency and dialect. HEXI surfaces the patterns — not just the failures.
Dialect audio
Québécois ≠ Parisian. Colombian ≠ Castilian. You train against the variety you're targeting.
HEXI priority
Your lowest comprehension patterns surface first every session. The ring fills as gaps close.
Stop guessing
what you missed.
14 days. Your comprehension gaps. No approximations.
