How real-time voice translation works on Android
The key to real-time translation lies in artificial intelligence and natural language processing. These technologies allow us to analyze what you say, automatically translate it into the desired language, and reproduce it so the other person understands what you mean.

Some apps even allow both people to speak alternately, with everything translated instantly, making the conversation flow more naturally.
