Setting up the software and adding new voices is a straightforward process. Step 1: Install xVASynth
At its core, XVASynth is a machine learning-based speech synthesis app. It doesn't come pre-loaded with voices; it's a framework that requires you to install "voice models" or "voice packs" to function. These packs are AI models trained on voice data from specific characters in various video games. Once installed, you can type any text, and the software will generate an audio file of that character saying it. This allows modders to create new, immersive quests and dialogues without needing access to the original voice actors.
: Most packs allow you to adjust the pitch, duration, and energy of individual letters to fine-tune emotion and emphasis. Multilingual Capabilities
You need clean, high-quality audio files of the target voice. Aim for at least 30 to 60 minutes of audio for a basic model, though 2+ hours will yield much better results. The audio must be completely free of background music, sound effects, or overlapping dialogue. Step 2: Audio Preprocessing
As of 2025, development is moving fast. Here’s what to watch for:
Once training is complete, xVATrainer exports the models in the correct format required by xVASynth, ready for generating audio. You can share your custom voice packs with the community through Nexus Mods, Hugging Face, or Discord, expanding the library of available voices for everyone to use.
XVASynth voice packs are one of the most powerful tools ever given to the modding community. They allow quest mods to feel official, follower mods to have personality, and forgotten NPCs to finally speak.
: If the required game folder doesn't exist, you can simply create it. The files should be extracted so that all checkpoint files end up directly in that folder.

A voice pack is a collection of AI models for a specific game. The core principle is that an AI model is trained on audio of a voice actor's performance to learn their unique tone, cadence, and inflection. XVASynth can then use this model to generate entirely new sentences.
