## AI overview

Google researchers introduce an end-to-end speech-to-speech translation model that translates speech in real time while preserving the original speaker's voice, with a two-second delay. The system uses a streaming architecture, time-synchronized training data, and a scalable data-acquisition pipeline to support more languages and improve conversational naturalness.
