VoiceShield · PRODUCT BRIEF

ARCHITECTURE AND LIVE SCRIPT

Product brief for VoiceShield — a Logic Intelligence Technologies product. Architecture, prevention loop, and the live demo script in one page so evaluators see the full stack without splitting the pack.

FIVE SUBSYSTEMS

  1. 01

    INGEST

    SIP / WebRTC / PSTN resampled to 16-bit PCM at 16 kHz.

  2. 02

    WINDOW

    Silero VAD plus a 250–333 ms ring. Demo default is 333 ms.

  3. 03

    FEATURES

    LFCC, F0, harmonicity, phase continuity, energy slope.

  4. 04

    DECIDE

    Kalman fusion over 1.5 s → GREEN / AMBER / RED.

  5. 05

    ACT

    Phonemic challenge, block, and append-only audit. No waveform on disk.

NINE-MINUTE SCRIPT

  1. 01Open VoiceShield. State the product mission — cloned voices on telephony and enterprise channels.
  2. 02Start the live path. Speak ten seconds. Show GREEN and hop latency.
  3. 03Inject the cloned stream. Risk should cross 75% and arm the challenge.
  4. 04Switch Hindi / Tamil prompt. Fail-closed if clone injection stays on.
  5. 05Simulate a drop. Banner, ring buffer, jittered reconnect, resume.
  6. 06Open VAULT. Show session row and forensic export.
  7. 07Close on DPDP: no waveform persisted — only scores and outcomes.

FRONTEND

Next.js on Vercel. Web Audio. Exponential backoff.

WORKER

FastAPI WebSocket in apps/api. Render or GPU Space.

STORE

Supabase Auth + RLS. Feature vectors only. Never PCM.
