Rufa Labs: voice AI from Luxembourg. Try every tool here.
Rufa Labs is an AI lab from Luxembourg. We research and build our own speech and language models, from Lëtzebuergesch to 28 languages, and help businesses adopt AI that fits them: custom models, private hosting, call assistants and chatbots.
Models that hear, speak and think
Rufa Realtime (V1 · Beta)
Speech to speech. Talk to AI the way you talk to a person.
Rufa Realtime listens, thinks and answers out loud in one live conversation. You speak, it starts answering in a fraction of a second, in your language, and you can interrupt it at any time. Choose Realtime Flash for instant replies, or Realtime Brain (Rufa Brain 31B) for deeper answers and long instructions.
Rufa Ears
Speech to text. Speech recognition for Lëtzebuergesch, the way it is really spoken.
Rufa Ears turns Luxembourgish speech into clean, timed text: phone calls, meetings, interviews and voice notes. It is tuned on the language as people actually speak it, including the French, German and English words that come with it.
Rufa Ears Global
Speech to text. One model for the many languages of Europe.
Rufa Ears Global listens in Luxembourgish and the main European languages, so multilingual teams and customers are understood without switching tools.
Rufa Speak
Text to speech. Natural voices that speak their own language.
Rufa Speak reads any text in a natural, expressive voice. Each voice in the library belongs to a language and speaks it like a native. Pick a speaking role, such as reading, news, conversation, phone call or phone menu, and Rufa Speak adapts its delivery.
Rufa Voice Clone
Text to speech. Your own voice, ready to speak any text.
Rufa Voice Clone learns a voice from a short recording and speaks any text in it with Rufa Speak. It only clones a voice with the speaker’s recorded consent, and the voice stays yours: private to your account, removed whenever you ask.
Rufa Translate
Language model. Translate Luxembourgish, and 100+ more languages.
Rufa Translate turns text or speech in one language into another, from Lëtzebuergesch to English, French, German, Portuguese and 95+ more. It detects the language for you, keeps names, numbers and formatting, and a Rufa voice of the target language reads the result out.
Rufa Flash
Language model. The fast thinker for live conversations.
Rufa Flash understands Luxembourgish and answers within a fraction of a second. It powers live conversations and processes calls as they happen: translation, replies, intents and next steps.
Rufa Brain
Language model. Deeper reasoning over every conversation.
Rufa Brain reads whole calls and documents and returns what matters: summaries, corrections to transcripts, layouts by speaker and the answers your team needs. Rufa Flash is built for speed; Rufa Brain is built for depth.
An AI receptionist that answers every call
Rufa call assistants answer the phone in the caller's language (Luxembourgish, French, German, English, Portuguese and more), book appointments and take messages, through your own systems.
