Xvasynth Voice Packs Jun 2026

For the truly ambitious, xVASynth allows you to create custom voice packs . This requires intermediate Python knowledge, a good GPU (Nvidia preferred), and a dataset of clean voice lines.

: Modders use these packs to give "original" characters voices that match the vanilla game world without needing to hire voice actors for every line.

While XVASynth voice packs have many benefits, there are also some challenges and limitations to consider:

A "voice pack" is essentially a trained machine learning model. It contains hundreds of megabytes (sometimes gigabytes) of spectral data extracted from a game character’s original voice lines. Developers run these original lines through a neural network to teach the AI the unique characteristics of that voice: pitch, breathiness, regional accent, and emotional range.
