TTS is a library for advanced Text-to-Speech generation. It's built on the latest research, was designed to be achieve the best trade-off among ease-of-training, speed and quality. TTS comes with pretrained models, tools for measuring dataset quality and already used in 20+ languages for products and research projects.

Below you see Tacotron model state after 16K iterations with batch-size 32 with LJSpeech dataset.
"Recent research at Harvard has shown meditating for as little as 8 weeks can actually increase the grey matter in the parts of the brain responsible for emotional regulation and learning."

TTS provides a generic dataloader easy to use for your custom dataset.
You just need to write a simple function to format the dataset. Check datasets/preprocess.py to see some examples.
After that, you need to set dataset fields in config.json.
Some of the public datasets that we successfully applied TTS:
Here you can find a CoLab notebook for a hands-on example, training LJSpeech. Or you can manually follow the guideline below.
To start with, split metadata.csv into train and validation subsets respectively metadata_train.csv and metadata_val.csv. Note that for text-to-speech, validation performance might be misleading since the loss value does not directly measure the voice quality to the human ear and it also does not measure the attention module performance. Therefore, running the model with new sentences and listening to the results is the best way to go.
shuf metadata.csv > metadata_shuf.csv
head -n 12000 metadata_shuf.csv > metadata_train.csv
tail -n 1100 metadata_shuf.csv > metadata_val.csv
To train a new model, you need to define your own config.json to define model details, trainin configuration and more (check the examples). Then call the corressponding train script.
For instance, in order to train a tacotron or tacotron2 model on LJSpeech dataset, follow these steps.
python TTS/bin/train_tacotron.py --config_path TTS/tts/configs/config.json
To fine-tune a model, use --restore_path.
python TTS/bin/train_tacotron.py --config_path TTS/tts/configs/config.json --restore_path /path/to/your/model.pth.tar
To continue an old training run, use --continue_path.
python TTS/bin/train_tacotron.py --continue_path /path/to/your/run_folder/
For multi-GPU training, call distribute.py. It runs any provided train script in multi-GPU setting.
CUDA_VISIBLE_DEVICES="0,1,4" python TTS/bin/distribute.py --script train_tacotron.py --config_path TTS/tts/configs/config.json
Each run creates a new output folder accomodating used config.json, model checkpoints and tensorboard logs.
In case of any error or intercepted execution, if there is no checkpoint yet under the output folder, the whole folder is going to be removed.
You can also enjoy Tensorboard, if you point Tensorboard argument--logdir to the experiment folder.

Please send your Pull Request to dev branch. Before making a Pull Request, check your changes for basic mistakes and style problems by using a linter. We have cardboardlinter setup in this repository, so for example, if you've made some changes and would like to run the linter on just the changed code, you can use the follow command:
pip install pylint cardboardlint
cardboardlinter --refspec masterIf you like to use TTS to try a new idea and like to share your experiments with the community, we urge you to use the following guideline for a better collaboration. (If you have an idea for better collaboration, let us know)
- Create a new branch.
- Open an issue pointing your branch.
- Explain your idea and experiment.
- Share your results regularly. (Tensorboard log files, audio results, visuals etc.)
- Implement the model.
- Generate human-like speech on LJSpeech dataset.
- Generate human-like speech on a different dataset (Nancy) (TWEB).
- Train TTS with r=1 successfully.
- Enable process based distributed training. Similar to (https://github.com/fastai/imagenet-fast/).
- Adapting Neural Vocoder. TTS works with WaveRNN and ParallelWaveGAN (https://github.com/erogol/WaveRNN and https://github.com/erogol/ParallelWaveGAN)
