Why LLUMO Voice AI?

10X

Better visibility

Move beyond transcripts. Analyze audio, intent, responses, and conversation flow in one place..

80%

Faster issue detection

Instantly detect transcription errors, hallucinations, and failed responses before they impact users.

4X

Stronger AI performance

Continuously measure, track, and improve reliability across every call interaction.

End-to-End Call Analysis Across the Voice Pipeline

  • Evaluate every stage of a voice interaction, from audio input to final response.
  • Analyze calls from raw audio to structured transcripts with full conversational context.
Evaluate | Optimize | Automate - in one click! illusration

Voice-Specific Metrics

Measure clarity, repetition, latency, and response accuracy across interactions.

The Ultimate LLM Testing Playground

Conversation Flow & Intent Tracking

Track how well the system understands intent and maintains context across multi-turn conversations.

Senior LLM Engineer, OptiMind

Integration was surprisingly quick, took less than 30 minutes. Now every agent run automatically and logs into the debugger, so we catch failures before they cascade.

Ryan
