Impersonation
A stand-in sits the interview in place of the real candidate.
The problem
Remote voice interviews are easy to cheat.
Webcams and honor codes don't catch fraud that happens through the microphone — by someone who isn't the candidate, or who isn't really answering.
Reading AI answers
The candidate reads a pre-written or ChatGPT answer aloud instead of thinking.
Off-mic coaching
A helper off-camera feeds lines the candidate simply repeats.
Proctoring blind spots
Video watches the screen and room, not who is speaking, or how.
How it works
Two questions, asked of every answer.
Is this really the enrolled person, and are they genuinely answering? Three steps, in order.
01
Enroll
The candidate reads a random sentence in a short, timed window — a liveness step that captures a genuine, live reference voice.
02
Verify
Any later recording is matched against the enrolled voiceprint. Same person or not, with a clear accept/reject and a similarity score.
03
Exam mode
Scores speech naturalness — disfluencies, pauses, pacing — to tell genuine thinking-aloud from a read or fed answer.
