Modulate’s Ensemble Listening Model (ELM)

Most “voice AI” stacks treat audio like nothing more than words - transcribing what is said and tossing that to a language model.

Velma is different. It’s a voice-native model built on a unique ensemble architecture, able to understand voice conversations in all their nuance. The results speak for themselves:

Why We Built Velma

AI Should Understand People

Not the other way around.

That belief shaped how we built Velma. Through our breakthrough research, we developed an entirely new AI architecture for voice – the Ensemble Listening Model – designed to understand conversations directly rather than reduce them to text.

Velma is the first production ELM, trained on hundreds of millions of hours of real conversations to capture nuance, emotion, and intent with unmatched accuracy.
