What is Palabra.ai?
Palabra.ai is a speech AI company whose products centre on live translation of spoken language. It develops its own models for speech-to-text, text-to-speech and speech-to-speech translation and offers them in two forms. Developers can call a streaming API over WebRTC or WebSocket that handles recognition, translation and voice output in one pipeline, with SDKs and a browser playground. Non-technical teams can use ready-made tools that add two-way voice translation and translated captions to Zoom, Google Meet and Microsoft Teams calls, in-person events, webinars and live streams delivered over SRT or RTMP. More than 60 languages are covered, and the service can clone a speaker's voice so the translated audio resembles the original. Custom glossaries keep specialist terms consistent. The company says conversation data is encrypted and not stored.
Key Features
Speech-to-Speech Translation
Translates live speech into another language with a stated delay of under one second, in both directions for conversations.
Voice Cloning
Reproduces the speaker's voice automatically for the translated audio, or uses a voice from the built-in library.
Translated Captions
Shows the translation as on-screen text so listeners can read instead of, or as well as, listening.
Meeting Integrations
Works inside Zoom, Google Meet and Microsoft Teams calls without extra software or plugins.
Broadcast Workflows
Accepts SRT and RTMP streams and fits into OBS, vMix, YouTube and similar setups to add translated audio tracks.
Developer API and SDKs
Exposes recognition, translation and speech synthesis through one streaming API with automatic language detection and glossary support.
