Read full descriptionHide full description
Most learners never hear what their accent actually sounds like. AccentMirror fixes that. Record yourself speaking. Hear how a native speaker would sound saying the same phrase. Then get scored on exactly which sounds to fix. HOW IT WORKS Speak any phrase in the language you're learning. AccentMirror gives you two things: Stage 1 โ Speak freely. Hear yourself with a native accent. No pressure. Most learners are surprised by what they hear. Stage 2 โ The score. Re-record the same phrase for a full breakdown: an overall 0-100 score, Sounds / Rhythm / Flow sub-scores, word-by-word accuracy, and a specific coaching tip naming the exact sounds you need to fix and how โ tongue position, lip shape, airflow. Not "your pronunciation needs work." Exactly what to do, physically, right now. Scoring is powered by Microsoft Azure's pronunciation assessment engine, calibrated against real learner data. A 75 isn't easy. SUPPORTED LANGUAGES 15 language variants across 9 languages, every one with full accent mirror support: English โ British and American French โ European and Canadian Spanish โ Spain and Mexico Portuguese โ Brazil and Portugal German, Italian, Japanese, Korean Mandarin โ China and Taiwan Cantonese Every language uses a native neural voice, so the accent mirror reflects how a real native speaker sounds โ not an approximation. More languages coming in future updates. WHO IT'S FOR Travellers who want to be understood, not just tolerated Professionals working in a second language who keep getting asked to repeat themselves Exam candidates preparing for IELTS, TOEFL, or oral language assessments Long-term learners who've studied grammar for years but still get told their accent is strong Anyone who's never actually heard what they sound like to a native speaker Beginners see the biggest gains. Advanced learners get the fine details that no teacher has time to catch.

Verdict
The clearest difference is in-app purchases: Shadow Flow at none against AccentMirror's 2. Shadow Flow also leads on ads (none vs shown) and update cadence (every 6 days vs every 2 weeks). On price, device support and iOS requirement there is nothing between them.
