What it is
A structured AI reading of signals in one recording.More than a random prank result
Many entertainment lie detector apps display a random answer. LieTone AI instead transcribes the recording, separates speakers when possible, and examines observable patterns in the words and audio.
The free result stays deliberately simple: Leans truthful or Leans deceptive, plus signal strength. Deep Read adds the moments and patterns that influenced that direction.
Three layers, viewed together
Voice over time
Changes in timing, pauses, energy, pitch, and other acoustic patterns—not a universal “lie signal.”
Context and speakers
The question, surrounding conversation, speaker focus, and whether different parts of an account fit together.
Can AI really detect a lie from voice?
Not with scientific certainty. There is no single vocal, emotional, or linguistic marker that proves deception across people and situations.
LieTone AI turns multiple observations into a directional second perspective. It must not be used to establish facts, accuse someone, diagnose a condition, or make legal, employment, medical, financial, educational, or safety decisions.
