Dock Evidence
DockWitness
DockWitnessDockWitnessDockWitness is a voice-first freight receiving evidence system that captures shortages, overages, visible damage, and two-party disagreements between receiver and driver in real time.
AI transcribes speech via AssemblyAI Universal-3.5 Pro. Pure code computes quantities and evaluates consensus. Verifiable facts are locked before the driver exits the dock gate.
Shortage (-1 carton) + Visible Damage (Carton 31) + Driver Disputes Shortage.
Expected 50, Observed 50. Zero damage. Clean bilateral agreement.
Expected 30, Observed 32 cartons. Driver confirms extra freight.
Carton 14 punctured. Hard evidence gate blocks review until photo attached.
Expected 25, Observed 24. Driver disputes count citing intact door seal.

Freight docks are noisy, fast-moving, and litigious. DockWitness separates acoustic recognition from truth adjudication.
Raw microphone audio is captured and downsampled via browser AudioWorklet to 16 kHz mono linear PCM (50ms frames, 800 samples) and streamed over WebSocket to AssemblyAI Universal-3.5 Pro.
Speech models transcribe verbatim words, but pure code computes math. Shortage calculations (Δ = Q_obs - Q_exp) and the 13-row agreement matrix run in pure deterministic TypeScript.
Every speech turn, photograph, calculation, and driver attestation is immutably recorded in an append-only audit trail. Physical carton damage triggers a mandatory photo evidence gate.
How DockWitness captures bilateral verification and records disagreement before the driver pulls away from the bay:
Receiver counts aloud while inspecting cartons at the trailer door.
16 kHz PCM16 frames parsed with keyterm boosting for numbers and freight codes.
Spoken quantity is extracted and compared against PO manifest. Discrepancy computed.
Driver provides voice or touch attestation (Confirm / Dispute). Silence is preserved.
Photo evidence gated, audit events immutably recorded, and ops manager notified instantly.
“DockWitness records disagreement. It never manufactures agreement.”
The system protects carriers and receivers alike. Disputed counts are recorded verbatim with quote provenance so claims can be resolved on objective facts rather than unverified paperwork.
