Three main processing steps enable instant communication

These devices perform a complex set of processes to turn one language into another. The first step involves speech recognition where microphones pick up the speaker's voice. High-end models use multiple sensors and specialized AI models to separate voices from background noise.

Machine translation handles audio processing tasks

The second stage is machine translation which processes the captured audio data. This step converts the recognized speech into text before moving to the final output phase. Some systems require users to hand over an earbud to the other speaker for this exchange.

Text-to-speech synthesis completes the conversion

The last step uses text-to-speech synthesis to generate spoken words in the listener's language. This process delivers the translated message within a few seconds of the original speech. Users can select specific languages in apps like Translate on an iPhone to start the session.
