Posted on July 20th, 2025 · 2 min read

Summary

I created the Wendigos Voice Cloning mod for Lethal company. This mod allows the masked enemies to mimic players' voices with AI voice cloning technology and reply to what players say using a Speech To Text (STT) model.

The mod utilizes a mix of local and cloud-based voice cloning AI models to acommodate users based on available processing power and budget. The mod also transcends language barriers, leveraging multilingual language models and speech detection to allow players to interact with the mod in their native language.
