Facebook开源VoiceLoop,一种在多个扬声器合成语音的方法

PyTorch通过语音循环实现了野外演讲者的语音合成中描述的方法。

VoiceLoop是一种神经文本到语音(TTS),能够在野外采样的语音中将文本转换为语音。 一些演示样品可以在这里找到

快速开始

按照安装程序中的说明,然后简单地执行:

python generate.py  --npz data/vctk/numpy_features_valid/p318_212.npz --spkr 13 --checkpoint models/vctk/bestmodel.pth

结果将放在models / vctk / results中。 它将生成2个样本:

You can also generate the same text but with a different speaker, specifically:

python generate.py  --npz data/vctk/numpy_features_valid/p318_212.npz --spkr 18 --checkpoint models/vctk/bestmodel.pth

Which will generate the following sample.

Here is the corresponding attention plot:

安装

Requirements: Linux/OSX, Python2.7 and PyTorch 0.1.12. The current version of the code requires CUDA support for training. Generation can be done on the CPU.

git clone https://github.com/facebookresearch/loop.git
cd loop
pip install -r scripts/requirements.txt

Data

用于训练本文中模型数据可以通过以下方式下载

bash scripts/download_data.sh

The script downloads and preprocesses a subset of VCTK. This subset contains speakers with american accent.

The dataset was preprocessed using Merlin – from each audio clip we extracted vocoder features using the WORLD vocoder. After downloading, the dataset will be located under subfolder data as follows:

loop
├── data
    └── vctk
        ├── norm_info
        │   ├── norm.dat
        ├── numpy_feautres
        │   ├── p294_001.npz
        │   ├── p294_002.npz
        │   └── ...
        └── numpy_features_valid

The preprocess pipeline can be executed using the following script by Kyle Kastner:https://gist.github.com/kastnerkyle/cc0ac48d34860c5bb3f9112f4d9a0300.

预训模型

Pretrainde models can be downloaded via:

bash scripts/download_models.sh

After downloading, the models will be located under subfolder models as follows:

loop
├── data
├── models
    ├── vctk
    │   ├── args.pth
    │   └── bestmodel.pth
    └── vctk_alt

SPTK and WORLD

Finally, speech generation requires SPTK3.9 and WORLD vocoder as done in Merlin. To download the executables:

bash scripts/download_tools.sh

Which results the following sub directories:

loop
├── data
├── models
├── tools
    ├── SPTK-3.9
    └── WORLD

训练

在vctk上训练一个新的模型,首先使用4的噪声级别和100的输入序列长度训练模型:

python train.py --expName vctk --data data/vctk --noise 4 --seq-len 100 --epochs 90

然后,继续训练模型使用2的噪声水平,完整序列:

python train.py --expName vctk_noise_2 --data data/vctk --checkpoint checkpoints/vctk/bestmodel.pth --noise 2 --seq-len 1000 --epochs 90
