Give your customers fine-tuned translations with the Microsoft Translator Hub API

You can now use the dictionary feature of the Microsoft Translator Hub API to give your customers fine-tuned translations, rather than the default translations generated by the Microsoft Translator Text API. Using this feature, you can edit any content translated by Microsoft Translator, and then redeploy the new, fine-tuned translations to your customers.

To use the dictionary feature of the Microsoft Translator Hub API, simply provide the original source text with your new, revised text and retrain your Microsoft Translator Hub system. Your customers will then be able to view the modified translation.

Additionally, you can use the dictionary feature of the Translator Hub API to give your customers standard translations of company-specific words and phrases; for instance, you can tell the Microsoft Translator Text API to translate your brand and product names just the way you want.

The Translator Hub API is a free extension of the Microsoft Translator service. It is fully integrated into the Translator Text API. With the Translator Hub API, enterprises and language service providers can build translation systems that understand the terminology used in their own business and industry. Your customized translation system will then easily integrate into your existing applications, workflows and websites, across multiple types of devices, through the regular Microsoft Translator Text API.

This capability was previously available in the Collaborative Translations Framework (CTF) but is now consolidated into the Translator Hub API. Using the Hub API to improve translations offers a number of advantages over the CTF:

  • It’s quicker and easier to use—you can update your translations in batches, instead of phrase-by-phrase as was possible in the CTF.
  • You can create your own app or workflow to automatically train and deploy customized translations with the new data.
  • You can control your data by explicitly choosing whether Microsoft Translator can use your translations to improve the overall translations provided by Microsoft Translator.

As mentioned in the Microsoft UserVoice support page, the CTF will be discontinued on January 31, 2018. After that time, customers will no longer be able to add new translations using the CTF.
