Why Voicely
The apps didn't fail you.
The model did.
Language fitness requires different tools than language learning. Duolingo built a habit loop. Voicely builds a skill.

Three reasons every app you've tried felt hollow.
Gamification ≠ Acquisition
XP rewards streaks and completion — not comprehension. Roediger & Karpicke (2006) showed that retrieval must be effortful to encode. A green owl congratulating you for guessing the same word twelve times doesn't make it stick. It makes it feel like it did.
Recognition ≠ Production
Reading, matching, and translating activate recognition memory. Swain's Output Hypothesis (1985) established that language is acquired through forced production — the act of constructing a sentence under pressure. Most apps keep you in recognition mode indefinitely, which is why you can read menus but can't order.
Generic ≠ Your language
French for Paris is not French for Montréal. Spanish for Madrid is not Spanish for Medellín. Dialect is not accent — it's vocabulary, register, rhythm, and cultural meaning. No other app addresses this. Voicely is built dialect-first.
Head to head
What each app actually delivers.
✓ full · ~ partial · ✗ not available · Assessment accurate as of 2026. Partial indicates limited or paid-only implementations.
The difference
Three things no other app does.
Four dimensions. Each earns independently.
Pronunciation, Comprehension, Production, Retention — each ring tracks a separate dimension of acquisition. You can't inflate your pronunciation score by doing grammar drills. Evidence-restricted means the score tells the truth.
Intelligence that compounds.
HEXI builds a model of your language across every session — what you know, what you're forgetting, and what you're ready to learn next. Anderson ACT-R (1983): skill acquisition requires thousands of retrieval attempts spaced at the right intervals. HEXI manages this automatically.
Phoneme-level truth.
Azure Speech SDK scores every phoneme you produce — not just the word. The UUS scorecard shows which sounds are correct, which are close, and which need work. You hear the gap. You close it. That's not possible in any other consumer app.
DeKeyser (2007)
Proceduralization requires thousands of production attempts under time pressure. Apps that avoid pressure avoid acquisition.
Krashen (1982)
Input at i+1 — one step beyond current level — is the primary driver of acquisition. Generic content doesn't calibrate to i+1.
Nation (2001)
Durable vocabulary requires receptive and productive exposure at the right interval. Spaced retrieval, not repetition.
Skehan (1998)
Task-based instruction under real communicative pressure accelerates automaticity beyond anything drill-based.
