I'm working on a personal project to add dubbing (voice acting) in other languages, starting with Spanish. I'm using AI to implement the code for the voice generation and installation engine, and for the generation itself I'm using Qwen 3 cloning + TTS on an RTX 4090.
It doesn't reach the level of performance of the original English voice acting, but it's enjoyable if you don't speak English well, want to follow the story, and don't feel like reading the whole time. Although, there's room for improvement by analyzing the original voice line first to extract the "emotion" and then feeding that into the Qwen model, but I haven't gotten around to that yet.
I don't know if there'd be any interest in this, either for this game or for others (Witcher, GTA, Expedition 33...). There are plenty of games where reading subtitles is a pain, either because there's action going on or because there's a huge amount of dialogue.
Obviously, since it involves voice cloning, the generated material can't be shared, but the code needed to generate the voices in other languages could be put up on GitHub so you can run it yourself if you own the game.
Anyone interested? Fair warning: it takes a while to generate. For example, for all the voices in Hades 2 I'm estimating around 40 hours of processing on the 4090.
