Rhythm before phonemes

Rhythm first — correcting individual phonemes while processing unfamiliar sentence rhythm creates cognitive overload. The order is deliberate.

Prosodic contour scoring

Stress patterns, liaison rules, and vowel linking scored separately from segmental phonemes. You see which dimension is holding you back.

Speed progression

0.75× → 0.9× → 1.0× → 1.1×. Once Echo Match Score passes 78, HEXI advances the phrase and selects the next prosodic gap.

Hear at speed

Native audio at natural pace. Full dialect. No slowing down. Your ear calibrates first.

Shadow live

You speak simultaneously with the native. Waveforms overlay in real time. EMS calculated.

See the delta

Rhythm, prosody, timing, phonemes — each dimension scored. Weakest gap isolated.

Drill the gap

Phoneme Focus for segmental gaps. Echo drill for suprasegmental. HEXI routes you.

Phrase pass

All four dimensions ≥ 74. EMS logged. Ring 1 score advances. HEXI selects next phrase.

Compound

Tonight's phrase becomes tomorrow's recall target. Prosodic memory compounds with each session.

Sound native.

Not just correct.
