SOVEREIGN VOICE STACK v2.1.2 · LIVE ON NODE 1

Voice infrastructure that
never leaves your perimeter.

A fully localized, GPU-accelerated acoustic pipeline for clinical and enterprise workloads. Whisper STT, a local extraction model, and Piper TTS — all running on hardware you control. 100% HIPAA compliant. Zero third-party API leakage.

On-premise execution — zero third-party API calls
THE SIGNAL CHAIN

One call, five steps, one machine.

Every call rides a single round trip through hardware you own — no hop ever touches a third-party API.

Stream opens

Twilio connects over a bidirectional WebSocket and starts sending audio frames.

event: start

Audio decodes

20ms G.711 µ-law frames are decoded to PCM16 and handed to CUDA-Whisper.

160B / 20ms

Speech transcribes

Whisper.cpp transcribes in real time on local GPU — nothing leaves the node.

whisper.cpp + CUDA

Response synthesizes

The transcript is extracted to structured JSON, then Piper TTS speaks the reply.

/v1/extract

Audio streams back

Mulaw frames return over the same socket. A mid-sentence interruption flushes the queue instantly.

event: clear

ACOUSTIC VOICE STREAM
WebSocket · G.711 µ-law · 8kHz mono · 20ms frames
wss://explorer-api.exergynet.org/media-stream

Establish a bidirectional Twilio <Connect><Stream> over WebSocket. The server ingests mulaw audio frames, transcribes via CUDA-Whisper, extracts structured intent, synthesizes TTS, and streams mulaw frames back — all within 1.24s average.

SOVEREIGN CLINICAL EXTRACTOR
REST · POST · JSON · Schema-aware structured extraction
POST https://explorer-api.exergynet.org/v1/extract

Pass raw clinical text and a typed schema. The extractor returns structured JSON with per-field confidence scores and clarification flags. No conversational prose leaks. Bypasses chat mode entirely.
