Speechdiff, a framework for diffusion applied to speech

The goal of this repository is to make it easy to experiment with audiodatasets and diffusion. This is powered by hydra, scorebased generative models (Song et al.) and Grad-TTS (Popov et al.).

At the moment it's currently a revamp of Grad-TTS

Installation

Python 3.9.17

pip install cython

pip install -r requirements.txt

cd model/monotonic_align; python setup.py build_ext --inplace; cd ../..

Train a Grad-TTS model

Create a filelist in the form f'{audio_path}|{transcription}|{speaker_id}' where speaker_id is an integer. Edit config/data/data.yaml to suit your dataset.

Run

python train_multi_speaker.py --config-name=config +data=data

Edit config as desired, or make use of hydra's multirun utility.

Evaluate a TTS model

First generate predictions for your dataset

python generate_tts_preds.py --config-name=config +data=delete_this +eval=eval

Then calculate log-f0 rmse

python evaluate_tts.py --config-name=config +data=data +eval=eval

Compute log-likelihoods

Coming soon
