[Amazon Translate](https://aws.amazon.com/translate/) is a neural machine translation service that delivers fast, high-quality, affordable, and customizable language translation. Today, we are enabling language detection for real time document translation. Customers can now automatically detect the source document's dominant language leveraging [Amazon Comprehend’s](https://aws.amazon.com/comprehend/) language detection API. Synchronous document translation supports language pairs with English as either the source or the target language, and document sizes up to 100KB.
