You post a word normally, then audio could be heared when you send a comment with a specific word that has been scripted to be part of the chat voice. Usually, chat voices have command boxes somewhere in the game so you can view the words with audio. Sadly, you can't microphone chat with users on Roblox, so sorry to ruin your dreams of an easier-to-talk Roblox system.
