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.
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.
Originally limited to English and Spanish, the feature received support for 12 new languages, still in testing, the following October. A January 2011 Android version experimented with a «Conversation Mode» that aims to allow users to communicate fluidly with a nearby person in another language. The Android app was released in January 2010, and for iOS on February 8, 2011, after an HTML5 web application was released for iOS users in August 2008. Google Translate is available in some web browsers as an optional downloadable extension that can run the translation engine, which allow right-click command access to the translation service.

- To acquire this huge amount of linguistic data, Google used United Nations and European Parliament documents and transcripts.
- Before October 2007, for languages other than Arabic, Chinese and Russian, Google Translate was based on SYSTRAN, a software engine which is still used by several other online translation services such as Babel Fish (now defunct).
- 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.
- Shortly after launching the translation service for the first time, Google won an international competition for English–Arabic and English–Chinese machine translation.
- It aims to translate whole phrases rather than single words then gather overlapping phrases for translation.

- It offers a website interface, a mobile app for Android and iOS, and an API that helps developers build browser extensions and software applications.
- 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.
- Google Translate can translate multiple forms of text and media, which includes text, speech, and text within still or moving images.
- 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.
- Because the API was used in numerous third-party websites and apps, the original decision to deprecate it led some developers to criticize Google and question the viability of using Google APIs in their products.
Furthermore, Google carried out a test that required native speakers of each language to rate the translation on a scale between 0 and 6, and Google Translate scored 5.43 on average. For many other languages vis-à-vis English, it can produce the gist of text in those formal circumstances. GNMT’s «proposed architecture» of «system learning» has been implemented on over a hundred languages supported by Google Translate. Google Translate’s neural machine translation system used a large end-to-end artificial neural network that attempts to perform deep learning, in particular, long short-term memory networks. Despite its role in improving translation quality and expanding language coverage, Google closed the Translate Community on March 28, 2024.

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.

For 67 languages, a minimally comprehensible result is not achieved 50% of the time or greater. Human evaluation from English to all 102 languages shows that the main idea of a text is conveyed more than 50% of the time for 35 languages. Accuracy decreases for those languages when fewer of those conditions apply, for example when sentence length increases or the text uses familiar or literary language.
Google Translate recognises the text from the image using optical character recognition (OCR) technology and gives the translation. The ‚Camera input‘ functionality allows users to take a photograph of a document, signboard, etc. The Android app is compatible with devices running at least Android 2.1, while the iOS app is compatible with iPod Touches, iPads and iPhones updated to iOS 7.0+. In February 2010, Google Translate was integrated into the Google Chrome browser by default, for optional automatic webpage translation. Users can save translation proposals in a «phrasebook» for later use, and a shareable URL is generated for each translation.
Results are sometimes shown with dictional information below the translation box, but it is not a dictionary and has been shown to invent translations in all languages for words it does not recognize. Since Google Translate uses statistical matching to translate, translated text can often include apparently nonsensical and obvious errors, often swapping common terms for similar but nonequivalent common terms in the other language, as well as inverting sentence meaning. It is a rule-based translation method that uses predictive algorithms to guess ways to translate texts in foreign languages. Although Google has deployed a new system called neural machine translation for better quality translation, there are languages that still use the traditional translation method called statistical machine translation. Before October 2007, for languages other than Arabic, Chinese and Russian, Google Translate was based on SYSTRAN, a software engine which is still used by several other online translation services such as Babel Fish (now defunct). By detecting patterns in documents that have already been translated by human translators, Google Translate makes informed guesses (AI) as to what an appropriate translation should be.

It aims to translate whole phrases rather than single words then gather overlapping phrases for translation. From October 2007, Google Translate used proprietary, in-house technology based on statistical machine translation instead, before transitioning to neural machine translation. Statistical models from these data are then used to translate between those languages. However, because English, like all human languages, is ambiguous and depends on context, this can cause translation errors.
Dialog – Translate Speech
Google representatives have been involved with domestic conferences in Japan where it has solicited bilingual data from researchers. To acquire this huge amount of linguistic data, Google used United Nations and European Parliament documents and transcripts. If Google were using an unambiguous, artificial language as the intermediary, it would be vous → you → Bы/вы OR tu → thou → ты. Because the API was used in numerous third-party websites and apps, the original decision to deprecate it led some developers to criticize Google and question the viability of using Google APIs in their products. In response to public pressure, Google announced in June 2011 that the API would continue to be available as a paid service. The technology underlying Instant Camera combines image processing and optical character recognition, then attempts to produce cross-language equivalents using standard Google Translate estimations for the text as it is perceived.
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.
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.

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 system’s original creator, Franz Josef Och, has criticized the effectiveness of rule-based algorithms in favor of statistical approaches. Google Translate does not apply grammatical rules, since its algorithms are based on statistical or pattern analysis rather than traditional rule-based analysis. In April 2006, Google Translate launched with a statistical machine translation engine. Until March 2023, some less widely spoken languages used the open-source eSpeak synthesizer for their speech; producing a robotic, awkward voice that may be difficult to understand. It is possible to enter searches in a source language that are first translated to a destination language allowing one to browse and interpret results from the selected destination language in the source language.

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.
