Tactical Voice Translation System
Real-time, fully air-gapped speech-to-speech translation for multinational tactical operations. Runs on-device with zero cloud dependency. Built for NATO interoperability on rugged edge compute.
What BlackSphere delivers to the warfighter
Operator speaks native language into tactical radio. Within seconds, the receiving operator hears a clear, natural-sounding translation in their own language. Bidirectional, full-duplex capable.
All AI inference runs locally on ruggedized edge hardware. No internet, no cloud, no call-home telemetry. Voice data never leaves the tactical network. Designed for TEMPEST-rated enclosures.
Plugs into existing tactical radio infrastructure via RoIP gateway. G.711 / MELPe codec bridge. Works with WaveRelay mesh, VHF/UHF, HF, and SATCOM radio networks.
Callsigns, brevity codes, grid references, and NATO phonetic alphabet pass through untranslated. "Bravo 2, this is Alpha 6, over" stays intact across all language pairs.
Real-time web UI for the operator: live transcription, language state, translation events, latency metrics, transcript export. Accessible from any device on the tactical LAN.
Automatic source language identification with operator override. Supports one-shot auto-detect mode and manual language seeding. Graceful fallback on low-confidence utterances.
End-to-end voice translation in under 3 seconds
Operator keys radio, speaks in native language
RoIP gateway bridges radio audio to G.711 RTP multicast
On-device AI: speech recognition, translation, voice synthesis
Translated audio paced at native codec rate back through gateway
Receiving operator hears translated voice on their radio
Bidirectional voice translation bridging two radio networks through a single edge compute node
Same software stack scales across hardware tiers — customer picks the SKU that matches the mission
Sweet spot: modular GPU snaps off for missions where not needed. NATO-grade translation quality with large models. 128GB RAM future-proofs for model upgrades.
Multi-stream parallel translation for command posts. Can run 70B+ models. EPYC 64-core enables CPU-only fallback without GPU.
Designed for NATO operational environments and interoperability requirements
NATO MELPe narrowband voice coder compatibility. Native G.711 uLaw transport with codec bridge to MELPe at 600/1200/2400 bps for interoperability with legacy NATO radio equipment and SATCOM links.
Confidentiality metadata label syntax for translated content. All transcripts and translation logs carry NATO classification markings (NU through CTS). Enables proper handling of translated classified communications.
Joint C3 Information Exchange Data Model alignment for feeding translated communications into NATO C2 systems. Structured event output compatible with JC3IEDM message exchange patterns.
Hardware platform (Klas Voyager family) designed for TEMPEST-rated enclosure installation. No wireless emissions from compute module. All I/O via shielded Ethernet and audio cables.
NATO information assurance assessment framework alignment. Encrypted data at rest, secure boot chain, no external DNS resolution, no telemetry endpoints. Audit trail for all translation events.
All AI models licensed under Apache 2.0, MIT, or CC-BY-4.0. No non-commercial restrictions. No revocable license clauses. No foreign-government controlled model dependencies. Full IP freedom for defense procurement.
Purpose-built AI pipeline with defense-grade open-source models. All components Apache 2.0 / MIT / CC-BY-4.0 licensed.
Transducer architecture eliminates hallucination-class errors common in autoregressive models. Numerals, callsigns, and grid references transcribe accurately without creative inference. ~1s on GPU, ~0.5s on A4500.
Purpose-built translation model trained on 70B parallel-data tokens covering all European languages. Does not hallucinate fictional radio scenarios. Callsign-preservation prompt + post-processing glossary for NATO brevity codes across all supported language pairs.
Natural-sounding male voices optimized for radio clarity at G.711 8kHz bandwidth. Lead-in and tail silence prevent first/last syllable clipping on mesh radio keying. Per-language speech rate tuning for intelligibility over degraded channels.
Bare-metal deployment, no containers or orchestration overhead. Both AI services auto-start at boot. State persists across power cycles. Boot-to-ready under 15 seconds.
Designed from the ground up for classified operational environments
Comprehensive maintenance, updates, and operational support for the lifecycle of the deployment
Air-gapped delivery via secure removable media. Security patches, bug fixes, and performance improvements. Tested and validated before deployment.
Periodic AI model improvements as better open-source models become available. New language packs. Tactical corpus fine-tunes from field usage data.
Spare parts inventory via Klas partnership. Field-replaceable modules. Hardware diagnostics and preventive maintenance schedules.
Tiered response times based on severity. Remote diagnostic support (when network permits). On-site support for critical deployments. Operator training program.
What sets us apart from existing tactical translation solutions
Competitors offer "edge deployment" that still phones home for updates, telemetry, or license validation. BlackSphere is architected air-gap-first. No internet path exists in the production image. Zero capability degradation when disconnected — because it was never connected.
Drops into the tactical radio infrastructure already fielded. WaveRelay mesh, RoIP gateway, H-250 handsets — BlackSphere bridges them transparently. No new radios, no new protocols, no new training burden for operators.
All AI models are open-source with clean Apache 2.0 / MIT licenses. No Google, Microsoft, or Meta cloud requirements. No revocable license clauses. Full IP ownership and sovereignty for the customer nation.
