Universal translator Guide, Meaning , Facts, Information and Description
The universal translator is a fictional device common to many science fiction works; it is both convenient and almost always infallible. It offers an instant translation of any language, although 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. Usually it ignores any grammar rules between languages, giving it as perfect English.Most of the time, it's depicted as a machine that works with a communications monitor. An exception is the Babel fish from The Hitchhiker's Guide to the Galaxy, a small organism that fits in the user's ear. The universal translator is convenient when science is not the main priority, or when the author prefers to ignore linguistic issues.
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 logistical perspective (for example, aliens who still speak English when no universal translator is in evidence), and requires some suspension of disbelief when characters' mouths move in synch with the translated words and not the original language; nonetheless, it removes the need for cumbersome and potentially extensive subtitles.
