Mytour will walk you through how to set up voice chat on your Nintendo Switch. There are two ways to voice chat while playing compatible games on the Switch. You can use the Nintendo Switch Online app available for both Android and iOS devices. Additionally, the Switch supports voice chatting through a headset with a built-in microphone. Currently, games like Splatoon 2 and Fortnite allow voice communication. Following the launch of Nintendo's paid online service in September 2018, more games are expected to support this feature soon.
