What is Google Translate?

Google Translate is a free translation service that provides instant translations between dozens of 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 can I do to improve Translation quality?

If you encounter a translation that doesn't seem right, quite often Google Translate will have alternative results available. To view these, simply click the phrase in question. When you click a better alternative translation, Google Translate will learn from your feedback and continue to improve over time.

You can also help improve translation quality by using Translator Toolkit for translating or by uploading your translation memories into Translator Toolkit.
