Unet-TTS: Improving Unseen Speaker and Style Transfer in One-shot Voice Cloning

English | 中文

❗ Now we provide inferencing code and pre-training models. You could generate any text sounds you want.

⭐ The model training only uses the corpus of neutral emotion, and does not use any strongly emotional speech.

⭐ There are still great challenges in out-of-domain style transfer. Limited by the training corpus, it is difficult for the speaker-embedding or unsupervised style learning (like GST) methods to imitate the unseen data.

⭐ With the help of Unet network and AdaIN layer, our proposed algorithm has powerful speaker and style transfer capabilities.

✨Colab notebook is Highly Recommended for test.

⭐ Now, you only need to use the reference speech for one-shot voice cloning and no longer need to manually enter the duration statistics additionally.

😄 The authors are preparing simple, clear, and well-documented training process of Unet-TTS based on Aishell3.

It contains:

• One-shot Voice cloning inference
• The duration statistics of the reference speech can be estimated Automatically using Style_Encoder.
• Multi-speaker TTS with speaker_embedding-Instance-Normalization, and this model provides pre-training Content Encoder.
• Unet-TTS training
• C++ inference

Stay tuned!

Install Requirements

• Only support Linux system
• Install the appropriate TensorFlow and tensorflow-addons versions according to CUDA version.
• The default is TensorFlow 2.6 and tensorflow-addons 0.14.0.

cd One-Shot-Voice-Cloning/TensorFlowTTS
pip install . 
(or python setup.py install)

Usage

Option 1: Modify the reference audio file to be cloned in the UnetTTS_syn.py file. (See this file for more details)

cd One-Shot-Voice-Cloning
CUDA_VISIBLE_DEVICES=0 python UnetTTS_syn.py

Option 2: Notebook

Note: Please add the One-Shot-Voice-Cloning path to the system path. Otherwise the required class UnetTTS cannot be imported from the UnetTTS_syn.py file.

import sys
sys.path.append("<your repository's parent directory>/One-Shot-Voice-Cloning")
