A StyleTTS2 fine-tune, designed for expressiveness.


Vokan is an advanced finetuned StyleTTS2 model crafted for authentic and expressive zero-shot performance. Designed to serve as a better base model for further finetuning in the future! It leverages a diverse dataset and extensive training to generate high-quality synthesized speech. Trained on a combination of the AniSpeech, VCTK, and LibriTTS-R datasets, Vokan ensures authenticity and naturalness across various accents and contexts. With over 6+ days worth of audio data and 672 diverse and expressive speakers, Vokan captures a wide range of vocal characteristics, contributing to its remarkable performance. Although the amount of training data is less than the original, the inclusion of a broad array of accents and speakers enriches the model's vector space. Vokan's training required significant computational resources, including 300 hours on 1x H100 and an additional 600 hours on 1x 3090 hardware configuration.

V2 is currently in the works, aiming to be bigger and better in every way! Including multilingual support! This is where you come in, if you have any large single speaker datasets you'd like to contribute, in any language, you can contribute to our Vokan dataset. A large community dataset that combines a bunch of smaller single speaker datasets to create one big multispeaker one. You can upload your uberduck or FakeYou compliant datasets via the Vokan bot on the ShoukanLabs Discord Server. The more data we have, the better the models we produce will be!
