The feature listens to a call and shows or speaks a translation instantly.

A technology company showed a new phone feature on Monday that can translate conversations between two people in real time.

The feature listens to a phone call and uses artificial intelligence to translate what is said into the other person's language within a second or two.

The company said the tool currently supports twelve languages, with more planned for next year, and it works even without an internet connection.

Some experts are excited about the technology, but others say it still makes mistakes with slang and fast speech.
