Universal Translator - General

General

As a rule, a universal translator is instantaneous, but if that language has never been recorded, there is sometimes a time delay until the translator can properly work out a translation, as in the case of Star Trek. Some writers seek greater plausibility by instead having computer translation that requires collecting a database of the new language, often by listening to radio transmissions.

The existence of a universal translator is sometimes problematic in film and television productions from a logical perspective (for example, aliens who still speak English when no universal translator is in evidence and all characters appear to hear the appropriately translated speech instead of the original speech, the ability to speak in the language when direct translation is possible), and requires some suspension of disbelief when characters' mouths move in sync with the translated words and not the original language; nonetheless, it removes the need for cumbersome and potentially extensive subtitles, and it eliminates the rather unlikely supposition that every other race in the galaxy has gone to the trouble of learning English.
