Microsoft Cognitive Services provide out of the box and trainable machine translation.
The basic idea is that you build and then train your private systems with your translated documents or translation memories. Over time your machine translations will improve and match your terminology and phrasing.
Enable Microsoft MT
Go to Settings > Machine Translation and open the Microsoft (v2) configuration.
A new version Microsoft v2 MT connector is available in Wordbee Translator.
It adds customizable resilience with high-throughput machine translations and implements better error handling.
To get started you need to create Microsoft Cognitive Services Translate projects, one per language combination you want to train. Each project is assigned a "category ID”, which you will have o fill in the Edit/Add a Microsoft Hub project configuration window.
Check back with Microsoft, but the policy is that if you train the system with a set of quality approved words you get the same amount of words translated for free. A win-win proposal.
