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;
- ConsistencyTTA fine-tuned by optimizing the CLAP score;
- The diffusion teacher model from which ConsistencyTTA is distilled.
The first two models are capable of high-quality single-step text-to-audio generation. Generations are 10 seconds long.
