This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The onvrdisplaypresentchange property of the SpeechSynthesis interface represents an event handler that will run when the presenting state of a VR device changes — i.e. goes from presenting to not presenting, or vice versa (when the onvrdisplaypresentchange event fires).
Syntax
window.onvrdisplaypresentchange = function() { ... };
Examples
The presenting state of a VRDisplay can be checked using the VRDisplay.isPresenting property.
TBD.
