IBM Watson: Language Translator

Translate and publish text in real time for 11 different languages

Language Translator from IBM Watson provides an API for translating and publishing text for 11 different languages. The IBM Watson Translator block allows you to translate text, whether it's as short as a chat messages or long as a news article, and deliver it to any number of subscribers, in real time.


This block enables communication between multiple participants in their native languages. It supports English, French, and Spanish but with some modifications to the block code, additional languages can be supported easily.

A message is sent to the input channel. Then it is translated using IBM Watson API while the message is in transit. The published message is appended with a translation before it reaches subscribers.

Multilingual translation can be especially useful for use-cases like customer support, social apps etc.
