Microsoft has just released their Skype Translator Preview for Windows 8.1, which uses some pretty incredible advances in machine learning to translate conversations in real time. Kind of like the first step toward a real, honest-to-goodness Babel fish from the The Hitchhiker’s Guide to the Galaxy, if you will. Over 40 languages will be supported, but the preview is including English-Spanish translations to start. Pretty quick turnaround from only having the tech demo in May. And I’ve got to admit, given what they show in the heartwarming video that’s included, it looks to already be quite impressive at this stage.
