WhichLang
Which language is that?
Only for iPhone
Free
iPhone
Listen in and instantly see which language is being spoken around you – completely offline, without any audio ever leaving your device.
Which language is being spoken right now? WhichLang listens through your microphone and shows you in real time which language is spoken around you – with its confidence, for over 90 languages.
Just open the app and it starts. No tapping, no setup, no sign-up.
• IDENTIFIES OVER 90 LANGUAGES
From German, English, Russian and Turkish to Ukrainian, Arabic, Chinese, Japanese and many more. WhichLang shows the three most likely languages with a percentage – great for gauging certainty even between similar languages.
• COMPLETELY OFFLINE
All recognition runs on your device. No audio ever leaves your iPhone, and the app works without internet – on a plane, on the subway, abroad.
• PRIVACY FIRST
Audio is never recorded, stored, or transmitted. The microphone is only active while the app is open. No account, no ads, no tracking.
• LIVE DISPLAY
A level visualization shows you that WhichLang is listening, and results update smoothly as people speak.
• HISTORY (optional)
If you like, WhichLang remembers which languages were detected and when – the result only, never audio. Deletable anytime, stays local on your device.
Perfect for travelers, language lovers, people in multilingual settings, and anyone who ever wondered: "What language is that?"
WhichLang is free and contains no ads.
