Voice is the most powerful
signal your business ignores.

What transcripts miss
  • Transcripts strip away everything that makes a conversation real: tone, hesitation, stress, urgency, and whether the voice is even human.

  • 74% of enterprises faced deepfake or voice cloning incidents this year.

  • 44% of customers complain about verification friction.

  • Your agents literally cannot hear the difference between a real caller and a cloned voice anymore.

What Velma hears
  • Emotion and intent in real time

  • Synthetic vs. real voice detection in under 2.5 seconds

  • Manipulation tactics and social engineering patterns

  • Escalation risk before it becomes a complaint or a loss

Why teams
choose Modulate

Voice-native, not transcript-dependent
We built a new AI architecture specifically for voice. Velma doesn't convert to text and hope for the best. It processes audio the way humans actually hear it, through an Ensemble Listening Model that orchestrates specialized models for each signal.

Ranked #1 on 🤗 Hugging Face Speech Deepfake Arena. 98.9% accuracy. Half the error rate of the next best model. Detection in under 2.5 seconds.
10 to 100x more cost-effective

Enterprise-grade from day one
SOC 2. ISO 27001. GDPR ready. Already deployed across hundreds of millions of conversations for Fortune 500 companies. This is not a research project.
