Splatoon 2 voice chat features future clarified - set play appointments, private battle voice options

We’ve received a report that Splatoon 2 will be compatible with an upcoming app for smart devices that enhances online play. This app will link with the game and allow you to set a play appointment with your friends and teammates invited through your social media accounts. It also lets you match up with them directly in the game and voice chat with them too.

For example, during a Private Battle, you can voice chat with all of the connected friends when you divide into teams, but once teams are set, voice chat is switched to communication only between teammates in the same team. Also, you cannot communicate with random Inklings you don’t know.
