(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. The universal translator is often used in cases of contact with pre-warp societies such as in the Star Trek: The Next Generation episode "Who Watches the Watchers", and its detection could conceivably lead to a violation of the Prime Directive. Therefore, logically there must be some mechanism by which the lips of the speaker are perceived to be in sync with the words spoken. No explanation of the mechanics of this function appears to have been provided; the viewer is required to suspend disbelief enough to overcome the apparent limitation. Non-fictional translators Microsoft is developing its own translation technology, for incorporation into many of their software products and services. Most notably this includes real-time translation of video calls with Skype Translator. As of July 2019, Microsoft Translator supports over 65 languages and can translate video calls between English, French, German, Chinese (Mandarin), Italian, and Spanish. In 2010, Google announced that it was developing a translator. Using a voice recognition system and a database, a robotic voice will recite the translation in the desired language. Google's stated aim is to translate the entire world's information. Roya Soleimani, a spokesperson for Google, said during a 2013 interview demonstrating the translation app on a smartphone, "You can have access to the world's languages right in your pocket... The goal is to become that ultimate Star Trek computer." The United States Army has also developed a two-way translator for use in Iraq. TRANSTAC (Spoken Language Communication and Translation System for Tactical Use), though, only focuses on Arabic-English translation. The United States Army has scrapped the TRANSTAC Program and is developing in conjunction with DARPA, the BOLT (Broad Operational Language Translation) in its place. In February 2010, a communications software called VoxOx launched a two-way translator service for instant messaging, SMS, email and social media titled the VoxOx Universal Translator. It enables two people to communicate instantly with each other while both typing in their native languages.
