Custom AI simultaneous interpretation software — Whisper Large-v3 + Deepgram Nova-3 for ASR, SeamlessM4T + NLLB + DeepL for MT, ElevenLabs Turbo + Cartesia Sonic for voice-over. Sub-3s end-to-end on conferences, sub-1s for chat. Same team that built TransLinguist (75+ languages, 30,000+ interpreters, NHS NOE CPC framework, $4.2M ARR) and Rafiky (30,000+ events, 6,000+ interpreters, 200+ languages, ISO 27001). 625+ real-time products since 2005, SOC 2 Type II / HIPAA / GDPR.
We build custom AI simultaneous interpretation systems on a chained pipeline: ASR (Whisper Large-v3 / Deepgram Nova-3 ~150ms first partial) → MT (SeamlessM4T, Meta NLLB, DeepL, Google Translate) → TTS (ElevenLabs Turbo ~250ms first audio, Cartesia Sonic ~90ms). Total end-to-end under 3s for conferences, under 1s for live chat. Domain fine-tuning for legal / medical / finance jargon, 75+ languages, integration with WebRTC SFUs (mediasoup / LiveKit / Janus / Pion), Zoom / Teams / Meet, KUDO and Interprefy stacks. No matter the size or complexity of your project, we'll take it on and get it done — no excuses, no generic limitations.
Streaming pipeline: Whisper Large-v3 / Deepgram Nova-3 (sub-300ms first partial) → SeamlessM4T / NLLB direct text-to-text → ElevenLabs Turbo / Cartesia Sonic streaming TTS. End-to-end under 3s on conferences, under 1s for live chat captions.
Beyond word-by-word. We fine-tune SeamlessM4T or NLLB on your terminology, ship custom glossaries with DeepL Pro, plug in Translation Memory, and bias outputs against your style guide — legal / medical / tech / internal jargon all handled.
Speakers talk naturally; listeners hear translated audio in their language. SeamlessM4T direct speech-to-speech (16 languages) for sub-2s latency, or chained ASR → MT → TTS via ElevenLabs Turbo / Cartesia Sonic for 75+ languages. Adjustable voice clone, pacing, and SSML control.
Custom AI interpretation for every case — conferences (KUDO / Interprefy / Zoom), telemedicine (NHS-grade), live events, broadcast captions, customer support. Whisper / Deepgram + SeamlessM4T / NLLB + ElevenLabs / Cartesia. Secure, scalable, ISO 27001 / GDPR / HIPAA.
Have an interpretation idea? We turn it into a working pipeline — Whisper / Deepgram for ASR, SeamlessM4T / NLLB / DeepL for MT, ElevenLabs / Cartesia for TTS, plugged into your WebRTC stack.
Existing interpretation slow or inaccurate? We swap engines (e.g. Google MT → SeamlessM4T direct), add streaming, fine-tune on your glossary, drop end-to-end latency from 6s to under 3s.
Inherited a stalled interpretation product? We step in, fix the streaming gateway, retrain on real audio, swap to Whisper Large-v3 + Deepgram Nova-3, and bring it back to production.

TransLinguist (75+ languages, 30,000+ interpreters, NHS NOE CPC framework, $4.2M ARR) and Rafiky (30,000+ events, 200+ languages, ISO 27001) in production. 625+ real-time products since 2005, sub-3s ASR→MT→TTS pipelines on Whisper / Deepgram / SeamlessM4T / ElevenLabs / Cartesia in production.
Senior speech engineers, ML researchers (ASR / MT / TTS fine-tuning), QA, UI/UX, and DevOps for GPU pipelines — all in-house, EU/UK timezone. We think like product owners, not just coders.
625+ shipped products, 100% Upwork Job Success, 400+ honest reviews, sub-3s end-to-end interpretation, ISO 27001 / SOC 2 Type II / HIPAA / GDPR / FERPA frameworks deployed in production.
Real talk on Whisper, SeamlessM4T, ElevenLabs, latency budgets, NHS / ISO 27001 deployments — from the team that ships it.
Software that translates spoken language in real time during meetings, calls, or events. Our pipeline: ASR (Whisper Large-v3 / Deepgram Nova-3) → MT (SeamlessM4T / NLLB / DeepL) → TTS (ElevenLabs Turbo / Cartesia Sonic). End-to-end under 3s for conferences, under 1s for live chat captions — instead of stock SaaS or human-only interpretation.
Production benchmarks: BLEU 35–45 on SeamlessM4T direct S2S in 16 languages; chained Whisper Large-v3 + NLLB + ElevenLabs hits BLEU 40+ for business / education / medical use cases. Domain fine-tuning (legal, medical, finance) lifts BLEU another 5–10 points. TransLinguist (NHS NOE CPC) ships in production today.
For most meetings and customer-facing communication — yes. For high-stakes legal, diplomatic, or NHS clinical cases, AI runs alongside humans as a support layer (live captions + machine-assist), or backs up the human interpreter. TransLinguist combines both: 30,000+ human interpreters with AI captions / TTS overlay.
Yes — native WebRTC integration with mediasoup, LiveKit, Janus, Pion SFUs; bridges into Zoom, Microsoft Teams, Google Meet via Recall.ai or RTMP; KUDO / Interprefy interop; custom Twilio Voice / SIP / FreeSWITCH for telephony.
Yes. ISO 27001 (Rafiky), SOC 2 Type II / HIPAA / GDPR / FERPA frameworks deployed in production. Self-hosted faster-whisper / NeMo / NLLB on your infra (AWS / GCP / Azure / on-prem / air-gapped), TLS in transit + AES-256 at rest, PII redaction, audit logs, RBAC.
Yes. We fine-tune SeamlessM4T or NLLB on your real corpora (transcripts, glossaries, style guides), ship custom terminology dictionaries through DeepL Pro Glossary, plug in Translation Memory (XTM / SDL), and bias outputs against your house style — typically 5–10 BLEU lift over generic engines.
