Ensemble Listening Models for Voice Intelligence: Introducing Velma

This white paper explains why traditional large language models fall short when applied to real-world voice conversations and introduces a new architecture—Ensemble Listening Models (ELMs).

Converting audio clips into simple transcripts strip away critical signals like tone, emotion, timing, and intent, leading to inaccuracies and hallucinations in high-stakes use cases. Modulate proposes an alternative to monolithic LLMs for understanding not just the words in a conversation, but the true meaning.

Velma, Modulate's voice-native ELM, combines dozens of specialized models to deliver accurate, explainable, and cost-effective insight from live conversations. Gain a clear understanding of the limitations of today’s approaches and why a voice-first architecture unlocks a new generation of enterprise voice intelligence.
