Palabra AI is a London-based startup building real-time voice AI translation. Its speech-to-speech engine translates live conversations across 60+ languages in under one second, preserving the speaker's voice through automatic voice cloning. The product works with Zoom, Microsoft Teams, Google Meet, OBS, and YouTube, and is also available as an embeddable API with ultra-low-latency WebRTC and WebSocket streaming, custom glossaries, and enterprise-grade security. The company positions itself as roughly 9x cheaper than a human interpreter. In 2025 Palabra AI raised an $8.4M pre-seed round led by Alexis Ohanian's Seven Seven Six.
