Robust and fine-grained prosody control of end-to-end speech synthesis (with waveglow)

Pytorch Implementation of Robust and fine-grained prosody control of end-to-end speech synthesis (Unofficial)

This implementation uses the LibriTTS dataset.

Notes

1. dev branch: Tacotron2 with multispeaker (speaker embedding). Speaker information is only consumed by Decoder module, and Attention module doesn't see any of it (as authors' intention).
2. text_side branch: Text-side prosody control model implementation.
3. Speech-side prosody control and Prosody normalization are not implemented in current version, but you can simply add them on top of above branches.

Pre-requisites

1. NVIDIA GPU + CUDA cuDNN

Setup

1. Download and extract the LibriTTS dataset
2. Clone this repo: git clone https://github.com/keonlee9420/Robust_Fine_Grained_Prosody_Control.git
3. CD into this repo: cd Robust_Fine_Grained_Prosody_Control
4. Initialize submodule: git submodule init; git submodule update
5. Update .wav paths: sed -i -- 's,/home/keon/speech-datasets/LibriTTS_preprocessed/train-clean-100/,your_libritts_dataset_folder/,g' filelists/*.txt
   • Alternatively, set load_mel_from_disk=True in hparams.py and update mel-spectrogram paths
6. Install PyTorch 1.0
7. Install Apex
8. Install python requirements or build docker image
   • Install python requirements: pip install -r requirements.txt

Training

1. python train.py --output_directory=outdir --log_directory=logdir
2. (OPTIONAL) tensorboard --logdir=outdir/logdir

Training using a pre-trained model

(TBD)

Multi-GPU (distributed) and Automatic Mixed Precision Training

1. Not supported in current implementation.

Inference

1. Single sample: python inference.py -c checkpoint/path -r reference_audio/wav/path -t "synthesize text"
2. Multi samples: python inference_all.py -c checkpoint/path -r reference_audios/dir/path

N.b. When performing Mel-Spectrogram to Audio synthesis, make sure Tacotron 2 and the Mel decoder were trained on the same mel-spectrogram representation.
