Revelum × Hume: Detecting Voice Fraud in Real-Time
Our collaboration with Revelum creates a critical feedback loop for responsible AI development: Early Access to EVI: Revelum trains their models on Hume's cutting-edge voice technology, ensuring detection capabilities stay ahead of emerging threats before they reach malicious actors. Continuous Refinement: As Hume's emotionally intelligent voices become more sophisticated, Revelum's detection algorithms evolve in parallel. “By partnering with Hume, we’re taking a vital step toward building technology that anticipates — not just reacts to — the evolving tactics of bad actors seeking to misuse powerful models. Together, we’re staying one step ahead in ensuring generative AI is used responsibly.”
About Revelum
Revelum is an AI-native security platform that protects institutions from deepfake impersonations and fraud in real time. Founded by Enrique Barco in 2025, Revelum provides turn-key solutions and developer-friendly APIs to safeguard institutions from emerging threats in the era of AI-driven fraud.
Revelum’s strategic partnership with Hume AI ensures their detection systems can identify even the most advanced synthetic voices, including Hume's own Empathic Voice Interface (EVI).
The Demo: AI-Powered Fraud in Action
In a recent demo, Revelum showcased how attackers use AI voice agents to attempt account takeovers. The scenario: "Jake" calls customer support, claiming an AI assistant accidentally changed and deleted his password. The EVI-powered voice sounds natural, but Revelum's technology instantly flags the deepfake.
In real-time, Revelum’s platform provides:
- A call risk assessment analysis
- Real-time deepfake detection counts
- Precise timestamps of synthetic voice segments
The customer service agent receives an alert and initiates callback verification—stopping the attack immediately.

GAF Powers Professional Training with Hume’s Text-to-Speech
To support their extensive training programs and marketing initiatives, GAF leverages Hume's text-to-speech technology to make internal training videos and marketing voiceovers. Our partnership addresses several key needs: Professional training content: Delivering consistent, high-quality audio for thousands of contractors and employees. Marketing collateral: Producing engaging voiceovers for promotional content and product demonstrations. Scalable production: Generating content without the logistics and cost of traditional voice recording. Hume's voice design also proved ideal for GAF. The platform's natural, expressive voices maintain the authoritative yet approachable tone that GAF needs to communicate with contractors, retailers, and customers. Unlike synthetic voices that can sound robotic or overly casual, Hume's TTS technology delivers the polished, trustworthy quality expected from an industry leader.
