Accent Sherlock's answer:
Most accent tests hand you a label. Accent Sherlock plays a deduction game: it places your English accent on a world map first the region it was most likely shaped in, then a probable country when the signal is strong enough. It's also honest in a way accent tools usually aren't: every guess comes with a real confidence level, it shows its runner-up candidates, and it never claims certainty. And it works with ordinary sentences, no tongue-twisters, so English learners at any level can play.
Accent Sherlock's answer:
Three reasons: it's completely free with no signup and no result hidden behind an email wall; it gives you a richer answer (region → country on an interactive map, with confidence levels and alternatives) instead of a single label; and it's transparent — it's an open research and educational demo that tells you how it reasons, and your one-tap feedback genuinely improves the model rather than disappearing into a funnel.
Accent Sherlock's answer:
Non-native English speakers curious how their English actually sounds, students, professionals working in English, and language learners. Around them: English teachers who use it as a fun classroom opener, linguistics enthusiasts, and honestly anyone at a party who wants to see if an AI can call out where they're from.
Accent Sherlock's answer:
Accent Sherlock is a side quest of Mimica (mimica.talk), an AI tutor that teaches people to speak English with confidence. While building Mimica's voice stack, the team noticed the speech models could hear where an accent comes from — so they turned that into a free public demo. It's now a small research loop: people play, the detective guesses, and every "actually, I'm from…" reply teaches the model something new.
Accent Sherlock's answer:
A self-supervised speech model (Microsoft's WavLM) turns your voice into acoustic embeddings, lightweight classifiers trained on open research corpora map those to regions and countries, and OpenAI's Whisper acts as a language gate so it only judges English speech. The stack is PyTorch and FastAPI behind a plain-JavaScript web app, running on AWS.
Accent Sherlock's answer:
Accent Sherlock is free and has no enterprise customers, and it's used by English learners, teachers, and language enthusiasts worldwide.
