Lie Detector is a free Android app, which will let you test your friend’s lying or not, just by listening to your voice.

This App, the Lie Detector app, is used for testing whether the subject is telling the truth or not. We use a combination of several voice recognition technologies, including our own custom neural network.

We calculate the score, based on a weighted combination of features.

You need to click a microphone to begin the test. You need to ask a question and wait for a few seconds.

In this app, you can choose between two options:

Whether the subject is telling the truth or not.

The percentage of the truth.
