In a recent confirmation by Riot Games, it was mentioned that the company is working to create a system to “listen” to in-game voice chat. The goal here is to detect and prevent abusive and disruptive behavior. 

At first stage, the data collected will be used to improve the evaluation system. By doing this, they will have a proper language model to use the recordings they receive. According to Riot Games, they are intending to launch a beta version for this feature in late 2022.

One crucial point they reminded is that they will not use the feature during beta for evaluating any in-game reports. Since this system will require a lot of efforts to perfect, they do not want to cause any false punishments. Once they are confident that they can use this system without much issues, they will share the next steps of their plans with players.
