Many are saying that Google’s Pixel Buds translation will change the world: you can simply tap the right earpiece and issue a command to Google Assistant on the Pixel 2. If you tell it to “Help me speak Japanese” and then start speaking in English, the phone’s speakers will output your translated words as you speak them. The other party’s reply ( presumably in Japanese, because otherwise, what exactly are you playing at? ) will then play into your ear through the Pixel Buds.
As Google’s onstage demonstration illustrated, there appeared to be virtually zero lag time during the translation, though we’ll have to see how well that performance holds up in the real world with wonky Wi-Fi connections, background noise, and crosstalk. This is a momentous breakthrough, to say the least. Just 20 years ago, if you wanted to have a passage of text translated using the internet rather than tracking down someone that actually spoke the language, you likely did it through Altavista’s Babel Fish.
