Google Translate, a free online translation tool, can translate between 90 widely spoken and lesser-known languages, alphabetized from Afrikaans to Zulu, as of May 2015. Google advises that not all translations are error-free, and the accuracy of translations may vary between languages.
To take advantage of Google's free translation services, type text or enter a web address into the text box at Google Translate. Choose the text's language, or select Detect language to let Google's linguistic algorithms figure out the unknown language of origin. Next, select the destination language and click the Translate button to get a computer-generated translation. To translate an entire document, click the Translate a document link and upload the file from your computer.
Google provides a Google Translate app for Android on the Google Play store and an iOS version for use on the iPhone, iPad or iPod Touch. Both versions of Google Translate support 90 languages and can translate through voice, camera, keyboard or handwriting.
Google's translation services rely on collaboration between users and developers to verify and improve translations. The Google Translate Community, in beta version as of May 2015, allows Gmail and Google Account users to log in and contribute their expertise to develop more accurate translations.
