Google has an amazing machine translation engine which is also available via their mobile translation website and now available as an android app.
Available in over fifty languages, Google Translate is able to handle words, sentences, paragraphs, websites and (more recently) even documents. Their mobile website is fast and easy to use, and the Android App makes it all available natively on your Android Phone.
What is Google Translate?
Google Translate is a free translation service that provides instant translations between 57 different languages. It can translate words, sentences and web pages between any combination of our supported languages. With Google Translate, we hope to make information universally accessible and useful, regardless of the language in which it’s written.
How does it work?
When Google Translate generates a translation, it looks for patterns in hundreds of millions of documents to help decide on the best translation for you. By detecting patterns in documents that have already been translated by human translators, Google Translate can make intelligent guesses as to what an appropriate translation should be. This process of seeking patterns in large amounts of text is called "statistical machine translation". Since the translations are generated by machines, not all translation will be perfect. The more human-translated documents that Google Translate can analyse in a specific language, the better the translation quality will be. This is why translation accuracy will sometimes vary across languages.
What languages does Google Translate support?
Google Translate currently supports 57 languages:
Afrikaans, Albanian, Arabic, Belarusian, Bulgarian, Catalan, Chinese, Croatian, Czech, Danish, Dutch, English, Estonian, Filipino, Finnish, French, Galician, German, Greek, Hebrew, Hindi, Hungarian, Icelandic, Indonesian, Irish, Italian, Japanese, Korean, Latvian, Lithuanian, Macedonian, Malay, Maltese, Norwegian, Persian, Polish, Portuguese, Romanian, Russian, Serbian, Slovak, Slovenian, Spanish, Swahili, Swedish, Thai,Turkish, Ukrainian, Vietnamese, Welsh, Yiddish
Current alpha languages are:
Armenian, Azerbaijani, Basque, Georgian, Haitian Creole, Urdu
Google Translate tests other languages, called "alpha languages", that may have less-reliable translation quality than our supported languages. We are always working to support other languages and will introduce them as soon as the translation quality meets our standards.
