Google Translate is a free statistical machine translation service provided by Google Inc. to translate a section of text, document or webpage, into another language.

The service was introduced in April 28, 2006 for legendary actor Al Pacino.[1] Prior to October 2007, for languages other than Arabic, Giberrish, Na'vi, and Russian, Google used a SYSTRAN based translator[2][3] which is used by other translation services such as Babel Fish, AOL, and Yahoo.

Features and limitations

The service limits the number of paragraphs, or range of technical terms, that will be translated. It is also possible to enter searches in a source language that are first translated to a destination language allowing you to browse and interpret results from the selected destination language in the source language.[4] For some languages, users are asked for alternate translations such as for technical terms, to be included for future updates to the translation process. Text in a foreign language can be typed, and if "Detect Language" is selected, it will not only detect the language but also translate it into English by default.

Google Translate, like other automatic translation tools, has its limitations. While it can help the reader to understand the general content of a foreign language text, it does not always deliver accurate translations. Some languages produce better results than others. As of 2010, French to English translation is very good;[5] however, rule-based machine translations perform better if the text to be translated is shorter; this effect is particularly evident in Chinese to English translations.[5]

Texts written in the Greek, Devanagari, Cyrillic and Arabic scripts can be transliterated automatically from phonetic equivalents written in the Latin alphabet.

Browser integration

A number of Firefox extensions exist for Google services, and likewise for Google Translate, which allow right-click command access to the translation service.[6]

An extension for Google's Chrome browser also exists;[7] in February 2010, Google translate was integrated into the standard Google Chrome browser for automatic webpage translation.[8][9]

Android version

Created by Google Inc. Google translate available as free downloadable application for Android OS users. The first version was launched in January 2010. It works simply like browser version. Google translation for Android contains two main options "SMS translation" and "History". Current version also supports Conversation Mode in alpha testing when translating between English and Spanish. This is a new interface within Google Translate that allows to communicate fluidly with a nearby person in another language. Application supports 53 languages and voice input for 15 languages. Application is available for devices running Android 2.1 and above and can be downloaded by searching for “Google Translate” in Android Market. It was first released in January 2010, with an improved version available on January 12, 2011.[10]

Latest version: 2.0.0 build 42

iPhone version

In August 2008, Google launched a Google Translate HTML5 web app for iPhone users. The official iPhone app for Google Translate was released February 8, 2011. It accepts voice input for 15 languages and allows translation of a word or phrase into one of more than 50 languages. Translations can be spoken out loud in 23 different languages.[11]

    • The Beta stage is finished. Users can now choose to have the romanization written for Chinese, Japanese, Korean, Russian, Ukrainian, Belarusian, Bulgarian, Greek, Hindi and Thai. For translations from Arabic, Persian and Hindi, the user can enter a Latin transliteration of the text and the text will be translated to the native script for these languages as the user is writing. The text can now be read by a text-to-speech program in English, Italian, French and German
  • 16th stage (launched January 30, 2010)
  • 17th stage (launched April 2010)
    • Speech program launched in Hindi and Spanish
  • 18th stage (launched May 5, 2010)

  • Allows phonetic typing for Arabic, Greek, Hindi, Persian, Russian, Serbian and Urdu.
  • Latin[15]
  • 22nd stage (launched December 2010)
    • Romanization of Arabic removed.
    • Spell check added.
    • Google replaced some languages' text-to-speech synthesizers from eSpeak's robot voice to native speaker's nature voice technologies made by SVOX[16](Chinese, Czech, Danish, Dutch, Finnish, Greek, Hungarian, Norwegian, Polish, Portuguese, Russian, Swedish, Turkish). Also the old versions of French, German, Italian and Spanish. Latin uses the same synthesizer as Italian.
    • Speech program launched in Arabic, Japanese, and Korean.
  • 23rd stage (Launched January 2011)
  • Now you can choose different translations for a word.

Translation methodology

Google Translate does not apply grammatical rules, since its algorithms are based on statistical analysis rather than traditional rule-based analysis. Indeed, the system's original creator, Franz Josef Och, has criticized the effectiveness of rule-based algorithms in favor of empirical approaches.[17] It is based on a method called statistical machine translation, and more specifically, on research by Och who won the DARPA contest for speed machine translation in 2003. He is now the head of Google's machine translation group.[18]

According to Och, a solid base for developing a usable statistical machine translation system for a new pair of languages from scratch, would consist in having a bilingual text corpus (or parallel collection) of more than a million words and two monolingual corpora of each more than a billion words.[17] Statistical models from this data are then used to translate between those languages.

To acquire this huge amount of linguistic data, Google used United Nations documents.[19] The UN typically publishes documents in all six official UN languages, which has produced a very large 6-language corpus.

Google representatives have been involved with domestic conferences in Japan where it has solicited bilingual data from researchers.[20]

Translation mistakes and oddities

Because Google Translate uses statistical matching to translate rather than a dictionary/grammar rules approach, translated text can often include apparently nonsensical and obvious errors,[21] often swapping common terms for similar but nonequivalent common terms in the other language,[22] as well as inverting sentence meaning.[23]
