Since we are primarily a Mac house, I’ve only ever used Skype Translator on a trial basis since it is currently Windows-only. But it looks like it has a lot of promise for international orgs like mine. The premise is simple: real-time speech translation, a la the Hitchhiker’s Guide babelfish.
In the meantime, Google Translate is still my go-to for text translation. And if you get the mobile app (iOS · Android) and download the offline dictionaries, you can use the camera to get real-time translations. It's based on the old Word Lens app, and it's pretty magical.
