A different question changes everything.
Traditional detection
"Does this sound like AI?"

Many detection systems focus primarily on artifacts introduced during speech generation. As synthesis continues to improve, those artifacts can become less consistent.

PulmoForge
"Does this sound like a real human?"

Evaluates characteristics commonly found in natural human speech alongside broader acoustic patterns. The goal is to estimate whether a recording is more consistent with a human speaker or synthetic generation.

Multi-layer analysis
Four layers. One risk score.
01
Biological Liveness
Looks for characteristics commonly associated with natural human speech, including breathing behavior and vocal variation.
02
Acoustic Analysis
Examines changes in pitch, energy, and timing across the recording to identify patterns that differ from typical human speech.
03
Signal Integrity
Evaluates recording quality and the effects of common meeting and communication audio compression.
04
Ensemble Scoring
Combines observations from multiple analyses into a single confidence score rather than relying on any individual signal.
Adversarial testing
Tested against a changing threat.

Synthetic speech continues to evolve rapidly. Detection systems should be evaluated against a broad range of modern speech generation methods and real-world recording conditions.

Testing includes recordings captured under a variety of communication environments, including compressed meeting audio and noisy recordings representative of everyday use.

Why this matters
Trust in real-time communication is at risk.

High-quality synthetic speech is becoming increasingly difficult to distinguish by listening alone. Organizations need additional signals to help evaluate the authenticity of remote conversations.

PulmoForge is developing technology to support identity verification during voice communications by providing an additional layer of analysis alongside existing security measures.
