Vivox sent out the following

 

Vivox is pleased to announce that all authorized Nintendo Switch developers can now utilize the Vivox SDK on the Nintendo Switch system. This allows developers the choice to provide in-game voice chat capabilities over a headset plugged directly into the console. Vivox is eager to see game developers bring more communication options to Nintendo Switch. Having many communication options available, including crossplay voice chat across consoles and PCs, enhances the social angle of gameplay.
Developers interested in utilizing the Vivox SDK in their Nintendo Switch titles can reach out to Vivox through the developer’s existing account on the Nintendo developer portal, and from there can download and begin integration of the SDKs. Development teams have already brought Vivox into their Nintendo Switch ports with outstanding results, including Epic Games’ Fortnite. Hi-Rez Studio will also be leveraging the Vivox SDK for SMITE and Paladins in forthcoming game updates. That same functionality is now available to all publishers. Developers also have access to Vivox’s highly experienced support staff, who are on-call and ready to make sure every customer has a successful experience. Vivox is excited to see more customers joining the growing list.
“We’ve already seen a great deal of success with Nintendo and the use of our voice services in Fortnite,” said Dave Verratti, president of Vivox. “We are extremely proud to be a part of the Nintendo ecosystem. We’re happy to help Nintendo continue to push the envelope in their products by bringing gamers together through enhanced communications. Multiplayer games can and should excel on Nintendo Switch, and we’re excited to see the results of the Vivox SDK on Nintendo Switch.”
With the addition of Nintendo’s latest console, Vivox now officially powers crossplay-ready voice and text communication across every major gaming platform, allowing game developers to engage their audiences in the games they love through quick and easy communication.

This is very welcome news. Hopefully a lot comes from this,
