In 2024, a record of 110 languages including Cantonese, Tok Pisin and some regional languages in Russia including Bashkir, Chechen, Ossetian and Crimean Tatar were added. No measurement results have been provided by Google researchers for GNMT from English to other languages, other languages to English, or between language pairs that do not include English. It uses deep learning techniques to translate whole sentences at a time, which has been measured to be more accurate between English and French, German, Spanish, and Chinese. In November 2016, Google transitioned its translating method to a system called neural machine translation.
Och was the head of Google’s machine translation group until leaving to join Human Longevity, Inc. in July 2014. As of November 2025,update the following 249 languages, dialects and language varieties written in different scripts (240 unique languages and dialects) are supported by Google Translate. Google Translate also provides translations for Google Assistant and the devices that Google Assistant runs on such as Google Nest and Pixel Buds.

Moreover, a number of languages are translated into a sentence structure and sentence length similar to a human translation. When text is well-structured, written using formal language, with simple sentences, relating to formal topics for which training data is ample, it often produces conversions similar to human translations between English and a number of high-resource languages. Volunteers could select up to five languages to help improve translation; users could verify translated phrases and translate phrases in their languages to and from English, helping to improve the accuracy of translating more rare and complex phrases.

(English database designed and developed for Foras na Gaeilge by Lexicography MasterClass Ltd.) Welsh language data from Gweiadur by Gwerin. Therefore, long text should be transferred to a document form and translated through its Document Translate function. While edits of translations may be submitted, in Chinese specifically one cannot edit sentences as a whole.
Novelty websites like Bad Translator and Translation Party have used the service to produce humorous text by translating back and forth between multiple languages, similar to the children’s game telephone. In its Written Words Translation function, there is a word limit on the amount of text that can be translated at once. Google Translate makes statistical guesses that raise the likelihood of producing the most frequent sense of a word, with the consequence that an accurate translation will be unobtainable in cases that do not match the majority or plurality corpus occurrence. Among the top 100 words in the English language, which make up more than 50% of all written English, the average word has more than 15 senses, which makes the odds against a correct translation about 15 to 1 if each sense maps to a different word in the target language. Due to its identical choice of words without considering the flexibility of choosing alternative words or expressions, it produces a relatively similar translation to human translation from the perspective of formality, referential cohesion, and conceptual cohesion. A few studies have evaluated Chinese,citation needed French,citation needed German,citation needed and Spanishcitation needed to English, but no systematic human evaluation has been conducted from most Google Translate languages to English.
- The ‘Camera input’ functionality allows users to take a photograph of a document, signboard, etc.
- Google Translate recognises the text from the image using optical character recognition (OCR) technology and gives the translation.
- Most common English words have at least two senses, which produces 50/50 odds in the likely case that the target language uses different words for those different senses.
- The following languages do not have a direct Google translation to or from English.
Instead, one must edit sometimes arbitrary sets of characters, leading to incorrect edits. A 2010 analysis indicated that French to English translation is relatively accurate, and 2011 and 2012 analyses showed that Italian to English translation is relatively accurate as well. When Google Translate does not have a word in its vocabulary, it makes up a result as part of its algorithm. Since 2020, Google has phased out GNMT and has implemented deep learning networks based on transformers. Second, Google showed a proposed translation for a user to agree, disagree, or skip. When Google Translate generates a translation proposal, it looks for patterns in hundreds of millions of documents to help decide on the best translation.

Google Translate produces approximations across languages of multiple forms of text and media, including text, speech, websites, or text on display in still or live video images. Originally, Google Translate was released as a statistical machine translation (SMT) service. Rather than translating languages directly, it first translated text to English and then pivoted to the target language in most of the language combinations it posited in its grid, with a few exceptions including Catalan–Spanish. It served over 200 million people daily in May 2013, and over 500 million total vegas casino users as of April 2016update, with more than 100 billion words translated daily. To translate text, speech, and websites in more than 200 languages, go to Google Translate page. You can use the Google Translate app to translate written words or phrases.

The browser version of Google Translate provides the option to show phonetic equivalents of text translated from Japanese to English. If a user enters a URL in the source text, Google Translate will produce a hyperlink to a machine translation of the website. Additionally, Google Translate has introduced its own Translate app, so translation is available with a mobile phone in offline mode. Google Translate can translate multiple forms of text and media, which includes text, speech, and text within still or moving images.
The Google Translate app for Android and iOS supports 249 languages and can propose translations for 37 languages via photo, 32 via voice in “conversation mode”, and 27 via live video imagery in “augmented reality mode”. In May 2025, users across the web found that if a Traditional Chinese phrase entered in the French section is translated to Traditional Chinese, Google Translate will provide strange translations. Moreover, the system automatically identifies foreign languages and translates speech without requiring individuals to tap the microphone button whenever speech translation is needed. As of February 2010, it was integrated into browsers such as Chrome and was able to pronounce the translated text, automatically recognize words in a picture and spot unfamiliar text and languages. Launched in April 2006 as a statistical machine translation service, it originally used United Nations and European Parliament documents and transcripts to gather linguistic data.
For some languages, text can be entered via an on-screen keyboard, whether through handwriting recognition or speech recognition. In the web interface, users can suggest alternate translations, such as for technical terms, or correct mistakes. A petition for Google to add Cree to Google Translate was created in 2021, but it was not one of the languages in development at the time of the Translate Community’s closure. The input text had to be translated into English first before being translated into the selected language. Google Translate is a web-based free-to-use translation service developed by Google in April 2006.
- Higher scores for European can be partially attributed to the Europarl Corpus, a trove of documents from the European Parliament that have been professionally translated by the mandate of the European Union into as many as 21 languages.
- Tests in 44 languages showed that the “suggest an edit” feature led to an improvement in a maximum of 40% of cases over four years.
- Instead, it often translates first to English and then to the target language (L1 → EN → L2).
- Due to its identical choice of words without considering the flexibility of choosing alternative words or expressions, it produces a relatively similar translation to human translation from the perspective of formality, referential cohesion, and conceptual cohesion.
- Certain texts in Japanese have shown to be translated to “Replying to @sarah_mcdonald(s)” in English, often with no relation to the source text.

Despite this, Google initially did not hire experts to resolve this limitation due to the ever-evolving nature of language. Since SMT uses predictive algorithms to translate text, it had poor grammatical accuracy. It offers a website interface, a mobile app for Android and iOS, and an API that helps developers build browser extensions and software applications. The developer has not yet indicated which accessibility features this app supports. Privacy practices may vary, for example, based on the features you use or your age.
Most languages from Africa, Asia, and the Pacific, tend to score poorly in relation to the scores of many well-financed European languages, Afrikaans and Chinese being the high-scoring exceptions from their continents. Due to differences between languages in investment, research, and the extent of digital resources, the accuracy of Google Translate varies greatly among languages. Google Translate struggles to differentiate between imperfect and perfect aspects in Romance languages. The accuracy of single-word predictions has not been measured for any language. Most common English words have at least two senses, which produces 50/50 odds in the likely case that the target language uses different words for those different senses. When used as a dictionary to translate single words, Google Translate is highly inaccurate because it must guess between polysemic words.
Original versions of Google Translate were 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. Upon highlighting text in an app that is in a foreign language, Translate will pop up inside of the app and offer translations. The original January launch only supported seven languages, but a July update added support for 20 new languages, with the release of a new implementation that utilizes convolutional neural networks, and also enhanced the speed and quality of Conversation Mode translations (augmented reality). In January 2015, the apps gained the ability to propose translations of physical signs in real time using the device’s camera, as a result of Google’s acquisition of the Word Lens app. Many of the more popular languages have a “text-to-speech” audio function that is able to read back a text in that language, up to several hundred words or so. For some languages, Google Translate can synthesize speech from text, and in certain pairs it is possible to highlight specific corresponding words and phrases between the source and target text.
It is able to scan text or a picture using the device and have it translated instantly. It translates multiple forms of texts and media such as words, phrases and webpages. As of November 2025, Google Translate supports 249 languages and language varieties at various levels. You can also control what data is saved in your account with easy on/off controls, and even delete your data by date, product, and topic.
These suggestions may be included in future updates to the translation process. If “Detect language” is selected, text in an unknown language can be automatically identified. For most of its features, Google Translate provides the pronunciation, dictionary, and listening to translation. For example, if “習近平的裸體” (Xíjìnpíng de luǒtǐ; Xi Jinping in naked style) is entered, the translation “中國人民的愛” (Zhōngguó rénmín de ài), which means “what Chinese love”, will result. In May 2014, Google acquired Word Lens to improve the quality of visual and voice translation. In January 2010, Google introduced an Android app and iOS version in February 2011 to serve as a portable personal interpreter.
Google Translate is a multilingual neural machine translation service developed by Google to translate text, documents and websites from one language into another. Shortly after launching the translation service for the first time, Google won an international competition for English–Arabic and English–Chinese machine translation. However, if the source text is shorter, rule-based machine translations often perform better; this effect is particularly evident in Chinese to English translations. Higher scores for European can be partially attributed to the Europarl Corpus, a trove of documents from the European Parliament that have been professionally translated by the mandate of the European Union into as many as 21 languages. A word in a foreign language might have two different meanings in the translated language. Google Translate, like other automatic translation tools, has its limitations, struggles with polysemy (the multiple meanings a word may have) and multiword expressions (terms that have meanings that cannot be understood or translated by analyzing the individual word units that compose them).
