As a Roblox player, it is hard to find experiences that support voice chat. There are a few good examples, but no way to discover new and unique ones.
Some experiences put big “VOICE CHAT” tags in their titles. Did a page search for this tag and found 6 experiences with it in their name.
If Roblox were to address the issue of voice chat discoverability, people will be encouraged to try voice chat out or maybe even make their own voice chat experience!
