In the sci-fi cult classic "The Hitchhiker’s Guide to the Galaxy", you used to slide a yellow Babel fish into your ear to listen to translations instantly. But today, Google has invented an interim solution: which is a pair of earbuds costing $159 and baptized the 'Pixel Buds'. They work with Pixel smartphones and the Google Translate app to provide live translation.
How it works : One person wears the earbuds, while the other one holds the connected phone. The one with the earbuds speaks normally in his or her language (English is the default) then the app translates the talking and plays it loudly on the phone. And when the person holding the phone responds; his response is translated and played directly on the earbuds.
Google Translate service has already got a conversation feature, and its iOS or Android apps allow two users to speak freely as it automatically figures out what languages are being spoken and then translates them. Nevertheless, the noise in the background can make it hard for the app to capture what people are saying, and to tell when a person has stopped speaking and when to start the translation process.
The "Pixel Buds" have the capability to overcome these problems since the user has to tap and hold a finger on the right earbud while talking. Splitting the interaction between the phone and earbuds lets each person have control over the microphone and helps speakers maintain eye contact whilst conversing.
