Start free on Bluemix View demo

Language Translator translates text from one language to another. The service offers multiple domain-specific models that you can customize based on your unique terminology and language. Use Language Translator to take news from across the globe and present it in your language, communicate with your customers in their own language, and more.

How it works


The Language Translator service can be trained over time to provide better accuracy when running translations. To do this, Watson needs to learn from previous translations. Watson Language Translator takes specific terms and phrases into account, such as the names of people or products to ensure that they are translated correctly. Language Translator models can be created with the Watson Language Translator API. Find out more from the link below:
