How a bank deploys VoxShield
VoxShield is a stateless API that returns a calibrated fraud-risk signal. It drops into infrastructure banks already run — it never blocks a call itself; it routes high-risk calls to step-up verification.

Four integration patterns
Call-centre sidecar
Consume the Amazon Connect / Genesys media fork; show a live risk badge to the agent.
Real-time API into the fraud engine
Return a score + reasons to FICO Falcon / SAS as one more signal — no workflow change.
Voice-login liveness layer
Run alongside voice biometrics in the mobile app / IVR before authorising.
Telecom-layer screening
Screen suspicious calls before they reach the customer (CNAP / DoT fraud indicator).
On-premise · raw audio never leaves the bank · SHA-256 audit trail · never auto-blocks (routes to step-up). Aligned to RBI FREE-AI & DPDP.
Indian-language coverage & fairness
English-centric detectors false-flag Indian accents as "synthetic". VoxShield is tuned and measured on real genuine speech across 10 Indian languages, with per-language false-positive rates published — pick a language and a real-world condition and watch genuine speech read LOW. AI clones read HIGH.
Measured false-positive rate per language
Run python eval_languages.py --phone to populate real numbers.
Bank-scale live simulation
Fire a burst of concurrent calls at the live API — Indian caller identities, mixed genuine/clone traffic — and watch throughput, latency and the verdict stream in real time. The API is stateless, so this scales linearly with workers/hardware.
