Description
Real-time speech translation for iPhone and iPad — free companion to LLT Desktop.
Speak → Transcribe → Translate → Speak back. Optional text-to-speech plays the translation aloud. GDPR-compliant when used with your own Mac running LLT Backend: no cloud, no API keys, no data leaves your network.
KEY FEATURES
• Live speech-to-text in 40+ languages • Instant translation between any source and target language • Text-to-speech playback of the translation • Pick your engine: 5 options, local or cloud • vMix title integration over local Wi-Fi • OBS Browser Source overlay — host live subtitles on your local Wi‑Fi for OBS on your PC. • VRChat output — send subtitles straight to the in‑game chatbox over OSC. • Fully customisable overlay look — background and text colour, opacity, and border — applied live in the app and in OBS. • Toggle the original text on or off — show it alongside the translation, or give the translation the full space. • Background audio — keeps working when the app is minimized • Automatic transcript saving (TXT + SRT, ready for YouTube, Premiere, DaVinci) • On-screen subtitle overlay • Universal app — optimized for both iPhone and iPad
LOCAL MODE — GDPR-COMPLIANT
LLT Backend runs on your own Mac (Apple Silicon or any machine with an NVIDIA GPU). Audio is sent from your iPhone over local Wi-Fi and processed entirely on your own hardware using Whisper for transcription and Mistral for translation. Nothing leaves your network. Perfect for schools, hospitals, law firms, government agencies, broadcasters, and anyone with strict data protection requirements.
5 SPEECH ENGINES
• LLT Backend — Your own Mac, local Whisper + Mistral, no cloud • OpenAI Whisper — Highest transcription quality • Deepgram — Fastest real-time streaming • Google Cloud Speech — 125+ languages, built-in translation • Azure Speech — Enterprise-grade, built-in translation, low latency
VMIX INTEGRATION FOR LIVE PRODUCTIONS
Send translated captions directly to your vMix title inputs. Broadcasters, streamers, and conference producers can put real-time subtitles on screen without touching their main production computer. Your iPhone becomes the translation appliance.
TRANSCRIPTS AND SUBTITLES
Every session is automatically saved as timestamped TXT and SRT files on your device. Import directly into YouTube, Final Cut Pro, Premiere Pro, or DaVinci Resolve — no format conversion needed. Share via AirDrop, Mail, or any iOS share target.
PRIVACY
LLT Backend mode keeps everything on your local network — zero data transmission to third parties. When you use a cloud engine, you provide your own API key, and audio is sent directly from your device to that provider, never through Adelvo Software. No analytics, no tracking, no telemetry.
