Tap the mic, read the short passage on the screen, and stop. That's it. It takes about twenty seconds.
Everyone reads the same lines on purpose. If people could say whatever they liked, the AI would start guessing from the words they chose. With the same passage, the only thing left to compare is the sound: how the vowels are shaped, which syllables carry the weight, where a sentence speeds up and slows down.
Those patterns get compared with thousands of recordings of English spoken by people from all over the world. Back comes a region, usually a country, how sure the guess is, and the two runners-up. No account, nothing to install, and the whole thing takes less than a minute.
