Provided you meet the above condition, simply follow the below steps to enable the Spatial feature:
Spatial voice chat is nothing new as it can be heard a lot in games like Among Us and Sea of Thieves. The team at Roblox wanted to tackle the issue of children’s’ safety by requiring players to be the minimum age of 18 in order to use the spatial voice chat function.
“Roblox,” the gaming platform accessed daily by more than 43 million active users, many of them children, is garnering complaints from users, parents and privacy advocates after granting large groups of players access to a new voice chat feature last week.
Well, as you've probably surmised by this point, Roblox now has voice chat which was just released out of beta -- "Spatial voice chat," to be specific. Spatial voice chat is a feature that alters the volume (and sometimes the sound) of speakers depending on their position relative to you in the game world.
Note: All Roblox users must be age 18 or over to enable voice chat. Users must also verify their age by uploading Photo ID to a portal provided by Roblox. If users do not meet either of these requirements, all voice chat features will most likely be disabled and restricted from their account. Check out our Roblox Voice Chat Guide for more detailed explanations concerning these requirements.
With these steps completed, users with voice chat enabled should be able to communicate with each other in most Roblox experiences.
