I Built a GeoGuessr for Languages — Here's How I Made It Speak 8 Languages Overnight

I've sunk embarrassing hours into GeoGuessr. There's something deeply satisfying about squinting at a road sign in Cyrillic, spotting a right-hand-drive car, and triumphantly dropping a pin somewhere in rural Bulgaria. One evening, while half-listening to a Turkish podcast I didn't understand, it clicked — what if the clue wasn't a photo of a street, but the sound of a language? Think about it. You hear someone speaking. The rhythm, the vowels, the melody of the sentence. Can you tell Japanese from Korean? Portuguese from Spanish? Hindi from Urdu? That question became LinguaGuessr — a game where you listen to a language, pin its origin on a world map, and get scored by how close you land.
