Most browsers now support a native web speech API which allows users to transcribe speech to text and makes it easy for web developers to add voice activated features to websites. This would be incredibly useful for building webXR applications.
Thank you for bringing this feature request to our attention. While we do not actively support this plugin, I have brought attention to this internally and we may support it in the future, though I cannot provide a specific timeline or decision on when or if this feature will be implemented.
