Translation is one of the hardest challenges to tackle, but it is the most promising in the field of Artificial Intelligence.

Improved Accuracy, Faster Speeds, & New Languages

Earlier this year we launched our technology preview showcasing IBM Neural Machine Translation (NMT). This preview brought: improved speed, additional languages, and higher accuracy. We are now happy to state:

By default, all new Watson Language Translator users will gain access to our Neural Machine Translation (NMT) technology.

Neural Machine Translation is the latest method based on Deep Learning that has led to remarkable improvements in translation fluency, achieving higher human evaluations compared to previous technologies. With this update to our service, we expect users of Watson Language Translator to not only have the higher accuracy but take advantage of our new language support.

Languages Supported by Watson Language Translator:

Arabic, Catalan, Chinese (Simplified & Traditional), Czech, Danish, Dutch, English, Finnish, French, German, Hindi, Italian, Japanese, Korean, Polish, Portuguese (Brazil), Russian, Spanish, Swedish, and Turkish
