This repository is the official PyTorch implementation of our IJCAI-2022 paper, in which we propose SyntaSpeech for syntax-aware non-autoregressive Text-to-Speech.

Our SyntaSpeech is built on the basis of PortaSpeech (NeurIPS 2021) with three new features:

1. We propose Syntactic Graph Builder (Sec. 3.1) and Syntactic Graph Encoder (Sec. 3.2), which is proved to be an effective unit to extract syntactic features to improve the prosody modeling and duration accuracy of TTS model.
2. We introduce Multi-Length Adversarial Training (Sec. 3.3), which could replace the flow-based post-net in PortaSpeech, speeding up the inference time and improving the audio quality naturalness.
3. We support three datasets: LJSpeech (single-speaker English dataset), Biaobei (single-speaker Chinese dataset) , and LibriTTS (multi-speaker English dataset).

conda create -n synta python=3.7
condac activate synta
pip install -U pip
pip install Cython numpy==1.19.1
pip install torch==1.9.0 
pip install -r requirements.txt
# install dgl for graph neural network, dgl-cu102 supports rtx2080, dgl-cu113 support rtx3090
pip install dgl-cu102 dglgo -f https://data.dgl.ai/wheels/repo.html 
sudo apt install -y sox libsox-fmt-mp3
bash mfa_usr/install_mfa.sh # install force alignment tools

Please follow the following steps to run this repo.

You can directly use our binarized datasets for LJSpeech and Biaobei. Download them and unzip them into the data/binary/ folder.

As for LibriTTS, you can download the raw datasets and process them with our data_gen modules. Detailed instructions can be found in dosc/prepare_data.

We provide the pre-trained model of vocoders for three datasets. Specifically, Hifi-GAN for LJSpeech and Biaobei, ParallelWaveGAN for LibriTTS. Download and unzip them into the checkpoints/ folder.

Then you can train SyntaSpeech in the three datasets.

cd <the root_dir of your SyntaSpeech folder>
export PYTHONPATH=./
