MEASURED IMPACT ON MACHINE PERFORMANCE
<20ms Processing Latency
Real-time processing with no impact on conversation flow.
↑30% Turn Detection Accuracy
More precise end-of-speech detection for better response timing.
Cleaner Speech Segmentation
Precise VAD reduces false positives and missed speech in streaming pipelines.
FROM RAW AUDIO TO MACHINE-READY INPUT
From noisy audio to clean, structured input in real time.
Raw Audio Is Not Machine-Ready
Real-world audio is messy. Overlapping speakers, noise, and unclear boundaries break transcription and downstream systems.
- Multiple speakers overlap and confuse ASR
- Background noise corrupts transcription accuracy
- No clear turn boundaries for agents to respond
- Inconsistent input leads to unstable AI behavior
Your models are only as good as your audio.
Isolate Speech. Remove Interference. Deliver Clean Input.
Orpheus SDK is a real-time audio processing engine that isolates the dominant voice and removes background noise, delivering clean, structured audio for both live conversations and AI systems.
- Separates the main speaker from overlapping voices
- Suppresses background noise and interference
- Preserves speech clarity for accurate transcription
- Works in real time across live conversations
Clean voice. Clear structure. Reliable output.
HOW VOICE ISOLATION WORKS
From raw, overlapping audio to clean, structured input ready for transcription, analytics, and voice AI.
Real-time by design
Processes audio instantly during live conversations, with no delay or post-processing.
Separates the dominant speaker
Identifies and isolates the primary voice, even in overlapping or multi-speaker scenarios.
Removes noise and interference
Suppresses background noise, artifacts, and competing signals that degrade clarity.
Delivers machine- ready input
Outputs clean, stable audio optimized for transcription, analytics, and voice AI systems.
BUILT AS A REAL-TIME AUDIO PROCESSING SYSTEM
Combines voice isolation, VAD, and turn detection into a single pre-ASR pipeline.
WHERE VOICE ISOLATION MATTERS MOST
Designed for environments where overlapping speech, noise, and unclear audio break transcription, analytics, and voice AI systems.
Voice AI and conversational agents
Ensure clean input for accurate understanding, stable responses, and natural interactions.
Improve AI performance
Cleaner audio leads to better transcription and more reliable analytics.
Contact centers and support operations
Reduce repetition and miscommunication in real-time conversations with customers.
Comms platforms and voice infrastructure
Deliver consistent audio quality across users, devices, and unpredictable environments.
Built for Machine Pipelines, Not Playback
Hecttor Orpheus SDK sits between raw audio and ASR, structuring speech before it reaches downstream systems.
- Processes audio before transcription
- Improves input quality for AI systems
- No changes to existing architecture
- Works in real-time streams
FREQUENTLY ASKED QUESTIONS
What is voice isolation in audio processing?
Voice isolation separates the primary speaker from overlapping voices and background sounds, producing a clean signal that can be accurately processed by ASR and AI systems.
How is voice isolation different from noise cancellation?
Noise cancellation removes background sounds. Voice isolation goes further by separating the main speaker from other voices, making the audio usable for machine processing.
Can Hecttor handle multiple speakers on a call?
Yes. Hecttor isolates the dominant speaker and suppresses overlapping speech, improving clarity and transcription accuracy in multi-speaker environments.
How does voice isolation improve ASR accuracy?
By removing noise and separating speakers, Hecttor provides cleaner input to ASR systems, reducing word error rate (WER) and improving transcription consistency.
