Palabra.ai

Palabra.ai is an AI-powered live voice translation platform that enables real-time communication in 60+ languages for video calls, events, streaming, and API integration.

What is Palabra.ai?

Palabra.ai is a real-time speech translation platform built on a proprietary large language model (LLM). It takes live audio input from microphones, video calls, or streams and outputs natural-sounding translated audio or captions in over 60 languages. The platform is available as a web-based service with ready-to-use tools and as a streaming API/SDK for custom integrations. It is developed by Palabra AI, which received backing from Reddit co-founder's venture firm (TechCrunch, August 2025).

Key Features

• Ultra-low latency translation — Achieves sub-second end-to-end latency for real-time two-way speech translation, enabling natural conversations without delays.
• Voice cloning — Automatically replicates the speaker's voice in the translated output, with a library of alternative voices also available. Emotion transfer is planned for future release.
• Custom glossaries — Manage business-specific terminology and domain vocabulary to ensure accurate translations for technical fields.
• Speaker diarization — Identifies and differentiates between speakers in multi-participant conversations, maintaining context in translated output.
• Enterprise-grade security — All conversations are encrypted during transit; Palabra does not store any conversation data. Private cloud or on-premises deployment options are available for enterprise customers.
• Wide platform integration — Works directly with Zoom, Google Meet, Microsoft Teams, and integrates via SRT/RTMP with OBS, vMix, YouTube, Vimeo, and other streaming tools.
• Streaming API and SDKs — Provides WebRTC/WebSocket-based APIs for developers to embed real-time ASR, translation, and TTS into any application.

Who is it for?

• Global teams and remote workers — Use Palabra for multilingual video calls in platforms like Zoom, Meet, and Teams without needing a human interpreter.
• Event organizers and conference producers — Enable live, simultaneous audio translation for in-person, virtual, or hybrid events; attendees listen on their own devices.
• Content creators and streamers — Add real-time translated audio or captions to live streams on YouTube, Twitch, or other platforms via OBS or vMix integration.
• Developers and product teams — Integrate Palabra's API into apps (e.g., social commerce, dating platforms, customer support) to provide real-time voice translation features.

What can you do with Palabra.ai?

• Translate live conversations in video calls — Join a Zoom meeting and have all speech automatically translated into the participant's preferred language, with natural voice output.
• Add multilingual audio to live events — Stream an in-person keynote with real-time translation that attendees can hear on their phones via a dedicated stream.
• Enable two-way Q&A in webinars — Use Palabra's two-way translation to allow audience members to ask questions in their own language and receive answers in theirs.
• Stream translated content to global audiences — Configure OBS to send audio to Palabra and receive translated audio back in real time for live broadcasts.

How does Palabra.ai work?

Palabra processes audio through three stages: Automatic Speech Recognition (ASR) transcribes the source language, the proprietary translation model converts it to the target language, and Text-to-Speech (TTS) generates natural-sounding output with voice cloning. The entire pipeline is streamed via WebRTC or WebSocket, achieving under one second of total latency. Users can either use Palabra's ready-made tools (no code required) or integrate the API into their own applications.
