USTelco HD Voice delivers the full signal—uncompressed, uncompromised, and machine-optimized.

When Machines Listen, Every Bit Matters

Modern AI doesn't just hear calls—it interprets them. From transcription engines and fraud detection to real-time analytics and language processing, voice is now a high-resolution input stream. But low-fidelity voice degrades more than experience—it degrades results. Compressed audio. Dropped frequencies. Delayed packets. These don’t just interrupt—they corrupt the signal machines rely on to make meaning.

Why AMR-WB Is the AI Codec Standard

Unlike legacy codecs (G.711, G.729) which cut out higher frequencies and phonetic detail, AMR-WB (Adaptive Multi-Rate Wideband) preserves full-range audio between 50Hz–7,000Hz. This matters because:
  • NLP models depend on prosody, intonation, and syllabic integrity
  • Voicebots require phonetic clarity to differentiate intent
  • Emotion analysis tools need tone and pacing
  • Transcription accuracy hinges on the full acoustic signal
“AI doesn’t guess well when the data is distorted. USTelco HD Voice ensures the data is clean from the start.”
HD Voice doesn't just upgrade your UX—it improves your model outcomes.

AI Performance Gains from HD Voice

Integrating HD audio into your AI stack doesn’t just sound better—it performs better.

Application Standard Audio USTelco HD Audio
Transcription Accuracy 82–88% avg 94–98% avg
Sentiment Analysis Poor tone resolution Full emotional contour
Voicebot Intent Capture Misses nuanced phrasing High-resolution parsing
Fraud Detection (ASR/NLP) High false-positive rate Improved speaker fingerprinting
You’ve trained your AI to be precise. Give it input that’s worthy of it.

USTelco HD Voice is not available over public SIP.

Compatibility + Deployment

HD Voice works seamlessly with:
  • Cloud-based AI APIs (Google STT, AWS Transcribe, Deepgram, AssemblyAI)
  • On-premise NLP platforms (Nuance, IBM Watson, proprietary ML stacks)
  • Contact center platforms with voice AI overlays (Genesys, Five9, NICE)
Integrate it via:
  • SIP trunk with AMR-WB support
  • Private NNI connection (MegaPort, Equinix Fabric, AWS DC)
“If your AI stack can speak SIP, it can speak HD. We’ll handle the fidelity.”
