Amazon Translate is a neural machine translation service that delivers fast, high-quality, affordable, and customizable language translation. Today, we are introducing multidirectional custom terminology, to give you more control and flexibility over your translation workflows. Custom terminology is a feature of Amazon Translate that enables you to customize your translation of named entities such that your brand names, character names, model names, and other unique content using your terminology file. With multidirectional custom terminology, you no longer have to constrain yourself to set the first column of your terminology file as your source language. You will be now able to use the same terminology file to translate both to and from a specific language.
