PolyTalk is a self-hosted, open-source speech-to-speech translation platform that processes live audio entirely on your own infrastructure with sub-second latency. It supports over 30 languages and works with microphones, browser tabs, meetings, and audio streams without sending data to external cloud services. PolyTalk offers a free Community Edition and a paid Enterprise Workspace edition, both fully on-premise. It is built for organizations in healthcare, government, legal, education, and other fields requiring private, low-latency multilingual communication.
