Tacotron2

This is an implementation of Tacotron and Tacotron2.

Requirements

Python >= 3.6
tensorflow >= 1.11
pyspark >= 2.3.0
librosa >= 0.6.1
scipy >= 1.1.1
matplotlib >= 2.2.2
hypothesis >= 3.59.1

Preprocessing

preprocess.py <dataset> </input/dataset/dir> </output/dataset/dir>

Currently available dataset are,

Training

For training Tacotron itself, run the following command.

train.py --dataset=<dataset> --data-root=</output/dataset/dir> --checkpoint-dir=</path/to/model/dir> --hparams=<parmas>

For training Post-net of Tacotron (Mel to linear spectrogram conversion), run the following command.

train_postnet.py --dataset=<dataset> --data-root=</output/dataset/dir> --checkpoint-dir=</path/to/postnet/model/dir> --hparams=<parmas>

See Preprocessing for available dataset.

Synthesis

synthesize.py  --dataset=<dataset> --data-root=</output/dataset/dir> --checkpoint-dir=</path/to/model/dir> --postnet-checkpoint-dir=</path/to/postnet/model/dir> --hparams=<parmas>

How to use as an external library

This implementation supports Bazel build. You can add this repository as a external dependency in your Bazel project.

Add following lines to a WORKSPACE file of your project. These lines configure how to get Tacotron2 codes and what version you use.

git_repository(
    name = "tacotron2",
    remote = "git@github.com:nii-yamagishilab/tacotron2.git",
    commit = "138c7934e3c6d99238f8b6b84d6b0a30f4ea8b2e",
)

Then add a dependency of Tacotron2 to your BUILD file. For example, adding following lines enables your training script to use Tacotron2 codes.

py_binary(
    name = "train",
    srcs = [
        "train.py",
    ],
    srcs_version = "PY3ONLY",
    default_python_version = "PY3",
    deps = [
        "@tacotron2//:tacotron2",
    ],
)

Now you can import tacotron2 package in your training script.

ToDo

Add Tacotron2 model
Implement L2 regularization
More easy to use runnable example
