s, unless that problem is essential to the plot. To translate a new language in every episode when a new species or culture is encountered would consume time (especially when most of these shows have a half-hour or one-hour format) normally allotted for plot development and would potentially, across many episodes, become repetitive to the point of annoyance. Occasionally, alien races are able to extrapolate the rules of English from very little speech and then immediately be fluent in it, making the translator unnecessary.

While a universal translator seems unlikely, due to the apparent need for telepathy, scientists continue to work towards similar real-world technologies involving small numbers of known languages. See machine translation

. 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

John Crichton is injected with bacteria called translator microbes which function as a sort of "Universal Translator." The microbes colonize the host's brain stem and translate anything spoken to him/her/it, passing along the translated information to the host's brain. This does not enable the injected person to speak other languages; they continue to speak their own language and are only understood by others as long as the listeners possess the microbes. The microbes sometimes fail to properly translate slang, translating it literally. Also, the translator microbes are unable to translate the natural language of the alien Pilots because every word in their language can contain thousands of meanings, far too many for the microbes to translate, thus Pilots must learn to speak in "simple sentences." The implanted can learn to speak new languages if they want or to make communicating with non-injected individuals possible. The crew of Moya learned English from their human friend John Crichton, thereby being able to communicate with the non-implanted populace when the crew visited Earth. Some species, such as the Kalish, cannot use translator microbes because their body rejects them, so they must learn a new language the old-fashioned way.

In the universe of "The Hitchhiker's Guide to the Galaxy", universal translation is made possible by a small fish. The fish is inserted into the auditory canal where it feeds off the mental frequencies of those speaking to its host. In turn it excretes a translation into the brain of its host.

The book remarks that, by allowing everyone to understand each other, the babel fish has caused more wars than anything else in the universe.

The book also explains that the babel fish could not possibly have developed naturally and therefore proves the existence of God as its creator. Since God needs faith to exist, and this proof dispels the need for faith, this therefore causes God to vanish "in a puff of logic".

In the Star Control

Star Control is a science fiction computer game that was developed by Toys for Bob and published by Accolade in the early 1990s. Star Control still enjoys a cult following...

computer game series, almost all races are implied to have universal translators; however, discrepancies between the ways aliens choose to translate themselves sometimes crop up and complicate communications. The VUX, for instance, are cited as having uniquely advanced skills in linguistics and are able to translate human language long before humans are capable of doing the same to the VUX. This created a problem during the first contact between Vux and humans, in a starship commanded by Captain Rand. According to Star Control: Great Battles of the Ur-Quan Conflict, Captain Rand is referred to as saying "That is one ugly sucker" when the image of a VUX first came onto his viewscreen. However, in Star Control II, Captain Rand is referred to as saying "That is the ugliest freak-face I've ever seen" to his first officer, along with joking that the VUX name stands for Very Ugly Xenoform. It is debatable which source is canon. Whichever the remark, it is implied that the VUX's advanced Universal Translator technologies conveyed the exact meaning of Captain Rand's words. The effete VUX used the insult as an excuse for hostility toward humans.

Also, a new race called the Orz was introduced in Star Control II. They presumably come from another dimension, and at first contact, the ship's computer says that there are many vocal anomalies in their language resulting from their referring to concepts or phenomena for which there are no equivalents in human language. The result is dialogue that is a patchwork of ordinary words and phrases marked with *asterisk pairs* indicating that they are very loose translations of unique Orz concepts into human language, a full translation of which would probably require paragraph-long definitions. (For instance, the Orz refer to the human dimension as *heavy space* and their own as *Pretty Space*, to various categories of races as *happy campers* or *silly cows*, and so on.)

In the other direction, the Supox are a race portrayed as attempting to mimic as many aspects of other races' language and culture as possible when speaking to them, to the point of referring to their own planet as “Earth

,” also leading to confusion.

In Star Control III, the K’tang are portrayed as an intellectually inferior species using advanced technology they do not fully understand in order to intimidate people, perhaps explaining why their translators’ output is littered with misspellings and nonstandard usages of words, like threatening to “crushify” the player. Along the same lines, the Daktaklakpak dialogue is highly stilted and contains many numbers and mathematical expressions, implying that, as a mechanical race, their thought processes are inherently too different from humans’ to be directly translated into human language.

, the humans without translators are unable to understand the Ferengi (who likewise can not understand the English spoken by the Human observers) until the Ferengi get their own translators working. Similarly, throughout all Trek series, a Universal Translator possessed by only one party is able to audibly broadcast the results within a limited range, enabling communication between two or more parties, all speaking different languages. The devices appear to be standard equipment on starships and space stations, where a communicator pin would therefore presumably not be strictly necessary.

Since the Universal Translator presumably does not physically affect the process by which the user's vocal cords (or alien equivalent) forms audible speech (i.e. the user is nonetheless speaking in his/her/its own language regardless of the listener's language), the listener apparently hears only the speaker's translated words and not the alien language that the speaker is actually, physically articulating; the unfamiliar oratory is therefore not only translated but somehow replaced.
