Is it even possible to translate in real time? In many languages and sentences the meaning and translation needs to completely change all thanks to one additional word at the very end. Any accurate translation would need to either wait for the end of a sentence or correct itself after the fact.
Live translation is a well solved problem by this point — the translation will update as it goes, so while you may have a mistranslation visible during the sentence, it will correct when the last word is spoken. The user does need to have awareness of this but in my experience it works well.
Bear in mind that simultaneous interpretation by humans (eg with a headset at a meeting of an international organisation) has been a thing for decades.
