Voice Stress Analyzer

Can it hear the pressure?

Speak into your mic and watch a live 3D stress waveform read the tension in your voice — a playful lie-detector-style experience.

For entertainment only — this is not a real lie detector. Audio is analysed live on your device and never recorded or uploaded.

Speak normally for a few seconds to calibrate, then ask your subject a question. Watch the index spike on hesitation and tension. It's a party trick, not evidence.
