Your AI agents are deaf.We give them ears.

Every voice AI converts speech to text and throws away 50% of the signal. Orpheus gives your agent two ears: one to hear how the customer really feels, one to hear how the agent actually sounds. One API. Both sides of every call.

The problem nobody talks about

Your agent hears words.
It misses everything else.

A customer says "Sure, sounds good." Your agent hears agreement. But a human rep would hear the flat tone, the long pause, the falling pitch — and know the deal is about to die.

📉 20-30s

The drop-off window

Customers decide within 30 seconds if they're talking to a robot. Your agent doesn't know it's losing them because it can't hear the disengagement happening.

🎭 47%

Say yes, mean no

Nearly half of customers use polite language to mask their real reaction. "Let me think about it" means no. Your agent hears the words and schedules a follow-up that will never convert.

Acoustic intelligence

Today, zero AI agent platforms analyze vocal biomarkers in real time. Your agents optimize scripts and prompts while ignoring the richest signal in every call: the human voice.

What makes Orpheus different

Every competitor gives you one ear.
We give you two.

Imentiv hears the customer. Deepfake detectors hear the agent. Only Orpheus hears both sides of every call — in one API call.

👂
Ear 1 — Hear the customer

Paralinguistic Intelligence

Your agent finally understands HOW the customer feels — not from their words, but from their voice. 26 physiological biomarkers, extracted in real time, interpretable by your LLM.

  • Stress, arousal, engagement, confidence tracking
  • Pitch (F0), vocal tension (jitter), voice clarity (HNR)
  • Speech rate, pause patterns, hesitation detection
  • Trend analysis: what's changing right now?
  • Alerts: stress spikes, disengagement, fake enthusiasm
0.93+ AUC separating emotions
from identical words
one call
🔊
Ear 2 — Hear the agent

Humanness Intelligence

Your agent finally knows how it sounds. Before the customer hears it. A frame-level quality gate that catches every TTS artifact your ears would miss.

  • Humanness Score 0–100 per audio segment
  • Works across ElevenLabs, OpenAI, Cartesia, any TTS
  • Dimensional breakdown: pauses, intonation, tempo
  • Quality gate: block audio that sounds robotic
  • Benchmarking: compare TTS configs objectively
99.8% TTS detection accuracy
across all tested engines

Integration

One API call.
Both ears.

01

Send any audio chunk

During a live call, stream the customer's audio to Orpheus. Works with Retell, Bland, Vapi, Twilio, or any SIP/WebRTC stack.

02

Get the acoustic picture

Orpheus returns physiological biomarkers, paralinguistic state, trend analysis, and real-time alerts. Not a black-box emotion label — interpretable signals your LLM can reason about.

03

Feed it to your agent's LLM

Add the Orpheus context to your system prompt. Your agent now makes decisions based on how the customer sounds, not just what they say. Conversion goes up. Drop-offs go down.
