Asynchronous Voice Over IP (VoIP) is an excellent feature for online games to make the gameplay more interactive and engaging. Custom voice chat is a perfect way to enhance the gaming experience and allow players to communicate and coordinate better in the game.

But how can you implement custom voice chat using Lua in Roblox Studio? Don't worry! I will guide you through the process in this step-by-step tutorial.

Step 1: Setting up the Project

First, create a new Roblox Studio project or open an existing one. In the project, create a new Script object in the Workspace. Name it "VoiceChat".

Step 2: Importing the Voice Chat Module

We'll use the "rbx-voip" module for voice chat. To import it, go to the "Insert" tab and click on "Advanced Objects" and then "ModuleScript". In the "ModuleScript" properties, paste the following URL:

Name this ModuleScript "voip".

Step 3: Adding Listeners

In the "VoiceChat" script, we'll add two listeners: one for the "player added" event and one for the "player removed" event. This will allow us to keep track of the players in the game and update their voice chat accordingly.

local voip = require(game:GetService("ServerScriptService").voip)

local Players = game:GetService("Players")







Step 4: Creating the Voice Chat Handler

Next, we'll create the voice chat handler that will handle the transmission and reception of voice chat.

local voip = require(game:GetService("ServerScriptService").voip)

local Players = game:GetService("Players")

local function PlayerTalking(player, talking)

voip:PlayerTalking(player, talking)


voip:SetAudioDataHandler(function(player, buffer)

return buffer



Step 5: Testing the Voice Chat

Finally, we can test the custom voice chat by joining the game with two or more players and speaking into our microphones. The voice chat should be audible to all other players in the game.

To improve the quality of your custom voice chat system, consider the following tips:

  • Consider using a third-party voice chat service like Discord or TeamSpeak if you want to implement a more robust and reliable voice chat system. These services can integrate with your Roblox game and provide a better voice chat experience for your players.

  • Make sure to test your voice chat system with multiple players and in different environments to ensure that it works properly for all players.

  • Keep in mind that voice chat can be a sensitive and personal experience for some players, so make sure to include options to enable and disable voice chat, as well as mute and block players if necessary.

  • You can also add visual cues to your game to indicate which players are currently speaking or if voice chat is enabled or disabled.

  • To reduce latency and improve the quality of your voice chat, consider using a codec that is optimized for low-latency and high-quality audio, such as the Opus codec.

  • Make sure to follow Roblox's community guidelines and terms of service when implementing voice chat in your game to ensure that it is safe and appropriate for all players.

By following these tips, you can create a custom voice chat system that will enhance the gaming experience for your players and make your game more interactive and engaging.
