Your post absolutely makes sense, and it sounds like you've put a lot of thought into how AI voice synthesis could enhance modding, especially for something as expansive as Skyrim! You’re right — AI-generated voices could save modders a ton of time and effort when it comes to creating new, immersive dialog.
If you’re curious about tools that could achieve what you’re imagining, you might want to check out https://audiomodify.com/. It’s an AI voice synthesis platform that allows you to generate realistic voice lines. With this, modders could potentially type the desired dialog, fine-tune the tone or emotion (like shouting, whispering, laughing, or crying), and generate audio that matches existing characters' voices.
This kind of tool could be revolutionary for projects like RDO or large-scale DLC mods. Modders could even create a consistent voice for the Dragonborn or add new lines for existing NPCs like Lydia, Jordis, or custom quest givers without relying on splicing or tedious voiceover recordings.
While it might take some experimentation to get the pacing, intonation, and emotional tone just right, platforms like AudioModify could make the process much easier and more efficient. And as you mentioned, the end result wouldn’t require AI on the player’s side — it would just be pre-recorded audio files.
Give it a look and see if it sparks some ideas! I think this could be the future of immersive modding for games like Skyrim.
