Trusted by Fortune 500 companies to prevent fraud, ensure policy adherence, guardrail AIs, and uplift customer experience.
What Can You Do With Voice Intelligence?
Voice calls, voice AIs, voice interfaces - voice has rapidly gained importance in recent years. But as companies deploy more and more voice solutions, they're confronting a challenge - how can they know what's happening in all these conversations?
Many platforms today offer "AI-powered voice intelligence" - but look under the hood, and you'll find an LLM analyzing the transcript of the call. The problem is that this is too expensive to do at scale - and in many cases, misses critical nuance that's not captured in the transcript.
So Modulate built a better way. Velma is a truly voice-native AI, capable of understanding exactly what's happening in each conversation, escalating those that require your attention - and doing it at a fraction of the costs of an LLM, with greater accuracy.
But don’t just take our word for it - review the data for yourself!
Velma 2.0 outperforms all models from the leading AI research labs, resulting in a superior understanding of any audio conversation, at a significantly lower cost. Read morea bout our methodology.

Velma, Under the Hood
Upgrading from LLM to ELM
LLMs and other text-generation models are great at speaking. But understanding conversations demands a different kind of model.
Velma is an Ensemble Listening Model (ELM), a new architecture built to capture complete, nuanced understanding of the whole voice chat. While LLMs focus on text completion, and need to be carefully managed to deliver insights, ELMs are purpose-built to provide validated, real-time, and auditable insights regarding what’s happening in each conversation across your ecosystem.
Purpose-built for voice
Understand real conversation—intent, sentiment, context shifts, adversarial speech—without brittle prompting.
Transparency
Traceable, auditable outputs—built for trust, compliance, and high-stakes workflows.
Cost & Speed
Dramatically more efficient than LLM approaches, designed for real-time and large-scale deployment.
Why ELMs Over LLMs?
Unlike monolithic models like LLMs, ELMs like Velma are coordinated ensembles of specialized models—each focused on a different element of analysis—organized under a shared orchestration layer. The result is a system optimized for transparency, reliability, and cost - three criteria which are essential for enterprise AI deployments across the board.
How Velma Works
Specialized detectors
Velma runs hundreds of models in combination, each specialized in insights including:
Emotion and stress
Inappropriate or unexpected conduct
Detection and manipulation
Synthetic/AI speech likelihood
Customer-configured behaviors
Real-time Evaluation
Velma doesn’t just assess a conversation as a whole, but breaks it down for greater accuracy and transparency. Velma produces time-stamped scores and events tied to moments in the conversation—so you can see exactly when risk rises, behavior shifts, or intent changes
Orchestration and Fusion
The orchestration layer combines signals into higher-level judgments (for example: “is this caller likely fraudulent,” “should the agent escalate to get this call handled more effectively” or “is the AI voice agent going off the rails”) while preserving the evidence trail back to underlying signals.
One platform. Unlimited Insights.
