Anyone who likes this idea might also be interested in checking out RTranslator, an open source, on-device app, which has some similar functionality. You can connect two Bluetooth devices using this app to communicate between two people in different languages.

It can’t translate multiple speakera simultaneously or clone voices, but it’s very useful for traveling or communicating with friends and family in multiple languages. Especially since it does not need any connection, it comes in handy on the road when you might not have a reliable connection.
