Fool your friends into thinking they have any accent you want!
Simply open the app and tap the top right settings gear icon and you can set any message you want, like "Australian accent detected!" or "Thick French accent detected, with 90% confidence!".
After this is set, click the Microphone button.
Get your friend to read the randomly generated sentence and the app will present the message that you said!
Again, "Accent Detector PRANK" is a prank app and does not really detect accents (it does not require the microphone permission).
