Once you have two or more people in the same VR space, it is natural to want to speak with one another. Almost all VR devices have headphones and microphones so the hardware support is ubiquitous.
Presently, Unity Networking does not support voice chat (VoIP). But there are other solutions:
- Third-party packages such as Dissonance Voice Chat (https://assetstore.unity.com/packages/tools/audio/dissonance-voice-chat-70078) add voice chat over your existing network connection.
- Photon Voice (https://assetstore.unity.com/packages/tools/audio/photon-voice-45848). If you are already using Photon Unity Networking (PUN), this is the go-to package to use. If you are using Unity Network (UNet), then Photon Voice is not a great choice, or at least you'd need to establish separate connections for voice on the Photon network from your other networking.
- Oculus VoIP...
