## Description

This work proposes a *consistency distillation* framework to train
text-to-audio (TTA) generation models that only require a single neural network query,
reducing the computation of the core step of diffusion-based TTA models by a factor of 400.
By incorporating *classifier-free guidance* into the distillation framework,
our models retain diffusion models' impressive generation quality and diversity.
Furthermore, the non-recurrent differentiable structure of the consistency model
allows for end-to-end fine-tuning with novel loss functions such as the CLAP score, further boosting performance.

## Model Details

We share three model checkpoints:
- [ConsistencyTTA directly distilled from a diffusion model](
  https://huggingface.co/Bai-YT/ConsistencyTTA/blob/main/ConsistencyTTA.zip);
- [ConsistencyTTA fine-tuned by optimizing the CLAP score](
  https://huggingface.co/Bai-YT/ConsistencyTTA/blob/main/ConsistencyTTA_CLAPFT.zip);
- [The diffusion teacher model from which ConsistencyTTA is distilled](
  https://huggingface.co/Bai-YT/ConsistencyTTA/blob/main/LightweightLDM.zip).

The first two models are capable of high-quality single-step text-to-audio generation. Generations are 10 seconds long.

After downloading and unzipping the files, place them in the `saved` directory.

The training and inference code are on our [GitHub page](https://github.com/Bai-YT/ConsistencyTTA). Please refer to the GitHub page for usage details.
