multi-speaker-tacotron

This is an implementation of our paper from ICASSP 2020:
"Zero-Shot Multi-Speaker Text-To-Speech with State-of-the-art Neural Speaker Embeddings," by Erica Cooper, Cheng-I Lai, Yusuke Yasuda, Fuming Fang, Xin Wang, Nanxin Chen, and Junichi Yamagishi.

Please cite this paper if you use this code.

Audio samples can be found here: https://nii-yamagishilab.github.io/samples-multi-speaker-tacotron/

News:

2022-03-29: Migrated data from Dropbox to Zenodo.
2021-06-21: Added scripts for creating tfrecords to synthesize new texts using pretrained models. See directory synthesize_new_texts and its README.
2020-08-10: Added example scripts for our new paper accepted to Interspeech 2020, "Can Speaker Augmentation Improve Multi-Speaker End-to-End TTS?" See directory is20 and please also update your copies of tacotron2 and self-attention-tacotron repositories as these contain some necessary changes.

Dependencies:

It is recommended to set up a miniconda environment for using Tacotron. https://repo.anaconda.com

conda create -n taco python=3.6.8
conda activate taco
conda install tensorflow-gpu scipy matplotlib docopt hypothesis pyspark unidecode
conda install -c conda-forge librosa
pip install inflect pysptk

Install this repository

git clone https://github.com/nii-yamagishilab/multi-speaker-tacotron.git external/multi_speaker_tacotron

Install Tacotron dependencies if you don't have them already:

mkdir external
git clone https://github.com/nii-yamagishilab/tacotron2.git external/tacotron2
git clone https://github.com/nii-yamagishilab/self-attention-tacotron.git external/self_attention_tacotron

Note the renaming of hyphens to underscores; this is necessary because “-” is an invalid character in Python.

Next, download project data and models, ~~from the dropbox folder here: https://www.dropbox.com/sh/rq4lebus0n8tmso/AACldbmKDPRN9YiXrRROjtTSa?dl=0~~ The data has been moved to Zenodo. You can find it here: https://zenodo.org/record/6349897#.YkKR-C8Rr0o

Preprocessed VCTK data: in the data directory
VCTK Tacotron models: in the tacotron-models directory
VCTK Wavenet models: in the wavenet-models directory

Training from scratch using the VCTK data only is possible using the script train_from_scratch.sh; this does not require the Nancy pre-trained model which due to licensing restrictions we are unable to share.

To use our pre-trained WaveNet models, you will also need our WaveNet implementation which can be found here: https://github.com/nii-yamagishilab/project-CURRENNT-scripts

To obtain embeddings for new samples, you will need the neural speaker embedding code which can be found here: https://github.com/jefflai108/pytorch-kaldi-neural-speaker-embeddings

How to use

See the scripts warmup.sh (warm start training), train_from_scratch.sh (train on VCTK data only), and predictmel.sh (prediction). The scripts assume a SLURM-type computing environment. You will need to change the paths to match your environments and point to your data. Here are the parameters relevant to multi-speaker TTS:

source-data-root and target-data-root: path to your source and target preprocessed data
selected-list-dir: train/eval/test set definitions
batch_size: if you get OOM errors, try reducing the batch size
use_external_speaker_embedding=True: use speaker embeddings that you provide from a file (see the files in the speaker_embeddings directory)
embedding_file: path to the file containing your speaker embeddings
speaker_embedding_dim: dimension should match the dimension in your embedding file
speaker_embedding_projection_out_dim=64: We found experimentally that projecting the speaker embedding to a lower dimension helped to reduce overfitting. You can try different values, but to use our pretrained multi-speaker models you will have to use 64.
speaker_embedding_offset: must match the ID of your first speaker.

The scripts are set up using embedding_file="vctk-x-vector.txt",speaker_embedding_dim='200' which is default x-vectors. Please change it to embedding_file="vctk-lde-3.txt",speaker_embedding_dim='512' to use LDE embeddings from our best system.
