Live Translate

This was the first major update to the new S24 that Samsung announced at Unpacked, and that’s because it has real potential to help people communicate in a much easier way than before despite their different tongues. Note it’s currently limited to 17 languages to start, though Samsung is promising more will come with time.
You can access Live Translate directly from the Call app. You click on the three dots in the top right corner, hit call settings, and then select “live translate.” You then set it to your language, what voice you wish the translator to use, and the language of the other person you expect to speak to (unfortunately, live language recognition is available, at least not yet). You can also set language and voice presets for specific people in your contact list.
Then, when you hop into a call, hit the live translate button as it’s ringing. This will bring up the live translation transcription, which will show the text of your conversation and the direct translation. There’ll be a short delay between when the caller speaks and the translation comes up, so be ready for a fair few awkward pauses as it goes through.
