This repo contains official PyTorch implementation of:

• PortaSpeech: Portable and High-Quality Generative Text-to-Speech (NeurIPS 2021)
  Demo page | HuggingFace🤗 Demo
• DiffSinger: Singing Voice Synthesis via Shallow Diffusion Mechanism (DiffSpeech) (AAAI 2022)
  Demo page | Project page | HuggingFace🤗 Demo

We implement the following features in this framework:

• Data processing for non-autoregressive Text-to-Speech using Montreal Forced Aligner.
• Convenient and scalable framework for training and inference.
• Simple but efficient random-access dataset implementation.

## We tested on Linux/Ubuntu 18.04. 
## Install Python 3.6+ first (Anaconda recommended).

export PYTHONPATH=.
# build a virtual env (recommended).
python -m venv venv
source venv/bin/activate
# install requirements.
pip install -U pip
pip install Cython numpy==1.19.1
pip install torch==1.9.0 # torch >= 1.9.0 recommended
pip install -r requirements.txt
sudo apt install -y sox libsox-fmt-mp3
bash mfa_usr/install_mfa.sh # install forced alignment tool
