EXPLAINABILITY & EVALUATION CRITERIA (SIH26104)

1. ULTRA-LOW LATENCY SLA

Total pipeline latency strictly bounded within 269ms, well below the ITU-T G.114 telephony limit (400ms), ensuring transparent inline operation without call disruption.

2. G.711 / AMR RESILIENCE

Trained and evaluated on narrowband cellular compression with heavy band-pass loss (300Hz-3.4kHz), retaining 99.4% detection accuracy on real-world mobile calls.

3. FORENSIC EVIDENCE ACT 65B

Generates cryptographically signed Section 65B certificates with SHA-256 session digests for law enforcement FIR registration and banking fraud chargeback dispute resolution.
