On January 9, 2019 Microsoft made a series of updates to Immersive Reader a tool that helps make reading on a device easier. Especially early learners as well as people with Dyslexia and Dysgraphia.
Immersive Reader now supports language translation. You can hear how particular words sound in another language or even have the entire document translated and read to you in a different language.
I have a video overview below. You can also see the full list of new feature Microsoft announced on January 9, 2019 here.
