Safetensors files for Bark

This repository hosts safetensors files for Suno's Bark. They are directly converted by loading the model, and using safetensors.torch.save_model . These safetensors files only contain the model, and the config has been split to another file with the name model_name.json .

All original model files have been converted and had their configs extracted into json format.
For example, for model text , the safetensors file is text.safetensors , and the config file is text.json .

Bark (From original readme , modified to exclude information not relevant to this repo)

Bark is a transformer-based text-to-audio model created by Suno . Bark can generate highly realistic, multilingual speech as well as other audio - including music, background noise and simple sound effects. The model can also produce nonverbal communications like laughing, sighing and crying. To support the research community, we are providing access to pretrained model checkpoints ready for inference.

The original github repo and model card can be found here .

This model is meant for research purposes only. The model output is not censored and the authors do not endorse the opinions in the generated content. Use at your own risk.

Two checkpoints are released:

• small
• large

Model Details

The following is additional information about the models released here.

Bark is a series of three transformer models that turn text into audio.

Text to semantic tokens

• Input: text, tokenized with BERT tokenizer from Hugging Face
• Output: semantic tokens that encode the audio to be generated

Semantic to coarse tokens

• Input: semantic tokens
• Output: tokens from the first two codebooks of the EnCodec Codec from facebook

Coarse to fine tokens

• Input: the first two codebooks from EnCodec
• Output: 8 codebooks from EnCodec

Broader Implications

We anticipate that this model's text to audio capabilities can be used to improve accessbility tools in a variety of languages.

While we hope that this release will enable users to express their creativity and build applications that are a force for good, we acknowledge that any text to audio model has the potential for dual use. While it is not straightforward to voice clone known people with Bark, it can still be used for nefarious purposes. To further reduce the chances of unintended use of Bark, we also release a simple classifier to detect Bark-generated audio with high accuracy (see notebooks section of the main repository).
