When you click Start, Palabra uses your microphone to translate your speech in real time. Your audio isn't stored after the session.

Live translation you stop noticing

Real-time speech to speech translation on our own models, with your terminology and natural-sounding voices in 70+ languages.

Runs at conversation speed

As a real-time voice translator, Palabra transcribes, translates, and voices speech in short streaming segments, so there's no pause after every sentence. One input can stream into several languages at once.

Keeps what the speaker meant

The translation comes out as coherent sentences that carry the full nuance, even when some words have no direct equivalent in the target language. We build our own models for every step, so the message stays accurate from speaker to listener.

Translates like an insider

Names, product terms, and industry shorthand come out exactly as you set them. Choose a translation style and describe the topic and audience, so tone and word choice fit the context.

Palabra is a voice to voice translator that sounds human, with natural voices, native pronunciation, and adaptive pacing in each of 70+ languages and their regional variants.

Video Calls & Meetings
