What is Velma?

It's not another LLM Wrapper

LLMs and other text-generation models are great at speaking. But understanding conversations demands a different kind of model.

Most “voice AI” stacks fudge understanding by passing a text transcript through token-based LLM systems. Velma is built for prioritizing a complete, nuanced understanding of the whole voice chat - and delivers validated, real-time, and auditable insights regarding what’s happening in each conversation across your ecosystem.

It's not another LLM Wrapper

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.

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.

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.
