Wav2Lipv2

Inspired by the repository https://github.com/primepake/wav2lip_288x288, Wav2Lipv2 uses a newly trained 288 model to achieve higher quality results.

Additionally, by employing YOLO for facial detection, the overall effect is improved. You can compare and test the results in Linly-Talker. The model has been updated, and the comparison is as follows:

Wav2Lip	Wav2Lipv2
Wav2Lipv2.mp4	Wav2Lip.mp4

ER-NeRF

ER-NeRF (ICCV 2023) is a digital human built using the latest NeRF technology. It allows for the customization of digital characters and can reconstruct them using just a five-minute video of a person. For more details, please refer to https://github.com/Fictionarry/ER-NeRF.

Updated: Taking inspiration from the likeness of Obama, for better results, consider cloning and customizing the voice of digital personas for improved effectiveness.

MuseTalk

MuseTalk is a real-time, high-quality audio-driven lip synchronization model capable of running at over 30 frames per second on an NVIDIA Tesla V100 GPU. This model can be integrated with input videos generated by MuseV, forming a part of a comprehensive virtual human solution. For more details, please refer to https://github.com/TMElyralab/MuseTalk.

MuseTalk is trained to operate within the latent space of ft-mse-vae and offers the following features:

• Unseen Face Synchronization: It can modify unseen faces based on input audio, with a face region size of 256 x 256.
• Multi-language Support: Supports audio inputs in various languages, including Chinese, English, and Japanese.
• High-performance Real-time Inference: Achieves real-time inference at over 30 frames per second on an NVIDIA Tesla V100.
• Facial Center Point Adjustment: Allows the adjustment of the facial region's center point, significantly impacting the generated results.

LLM Multiple Model Selection

In the webui.py file, easily select the model you need. ⚠️ For the first run, make sure to download the model first. Refer to Qwen1.8B.

Coming Soon

Welcome everyone to provide suggestions, motivating me to continuously update the models and enrich the functionality of Linly-Talker.

Optimizations

Some optimizations:

• Use fixed input face images, extract features beforehand to avoid reading each time
• Remove unnecessary libraries to reduce total time
• Only save final video output, don't save intermediate results to improve performance
• Use OpenCV to generate final video instead of mimwrite for faster runtime

Gradio

Gradio is a Python library that provides an easy way to deploy machine learning models as interactive web apps.

For Linly-Talker, Gradio serves two main purposes:

1. Visualization & Demo: Gradio provides a simple web GUI for the model, allowing users to see the results intuitively by uploading an image and entering text. This is an effective way to showcase the capabilities of the system.

2. User Interaction: The Gradio GUI can serve as a frontend to allow end users to interact with Linly-Talker. Users can upload their own images and ask arbitrary questions or have conversations to get real-time responses. This provides a more natural speech interaction method.

Specifically, we create a Gradio Interface in app.py that takes image and text inputs, calls our function to generate the response video, and displays it in the GUI. This enables browser interaction without needing to build complex frontend.

In summary, Gradio provides visualization and user interaction interfaces for Linly-Talker, serving as effective means for showcasing system capabilities and enabling end users.

If considering real-time conversation, it may be necessary to switch to a different framework or customize Gradio. Looking forward to working together with everyone.

Start WebUI

Previously, I had separated many versions, but it became cumbersome to run multiple versions. Therefore, I have added a WebUI feature to provide a single interface for a seamless experience. I will continue to update it in the future.

WebUI

The current features available in the WebUI are as follows:

• Text/Voice-based dialogue with virtual characters (fixed characters with male and female roles)

• Dialogue with virtual characters using any image (you can upload any character image)

• Multi-turn GPT dialogue (incorporating historical dialogue data to maintain context)

• Voice cloning dialogue (based on GPT-SoVITS settings for voice cloning, including a built-in smoky voice that can be cloned based on the voice of the dialogue)

• Digital Persona Text/Voice Playback (based on input text/voice)

• Multiple modules➕Multiple models➕Multiple choices

  • Multiple role selections: Female/Male/Custom (each part can automatically upload images) Coming Soon
  • Multiple TTS model selections: EdgeTTS / PaddleTTS / GPT-SoVITS / CosyVoice / Coming Soon
  • Multiple LLM model selections: Linly / Qwen / ChatGLM / GeminiPro / ChatGPT / Coming Soon
  • Multiple Talker model selections: Wav2Lip / Wav2Lipv2 / SadTalker / ERNeRF / MuseTalk/ Coming Soon
  • Multiple ASR model selections: Whisper / FunASR / Coming Soon

  

You can directly run the web UI to obtain results. The page you will see is as follows:

# WebUI
python webui.py

This time, we've updated the interface. We can freely select the fine-tuned model of GPT-SoVITS to achieve voice cloning. Simply upload a reference audio file to clone the voice.

Old Verison

There are three modes for the current startup, and you can choose a specific setting based on the scenario.

The first mode involves fixed Q&A with a predefined character, eliminating preprocessing time.

python app.py

The first mode has recently been updated to include the Wav2Lip model for dialogue.

python appv2.py

The second mode allows for conversing with any uploaded image.

python app_img.py

The third mode builds upon the first one by incorporating a large language model for multi-turn GPT conversations.

python app_multi.py

Now, the part of voice cloning has been added, allowing for freely switching between cloned voice models and corresponding person images. Here, I have chosen a deep, smoky voice and an image of a male.

python app_vits.py

A fourth method has been added, which does not fixate on a specific scenario for conversation. Instead, it allows for direct input of voice or the generation of voice for the creation of a digital human. It incorporates methods such as Sadtalker, Wav2Lip, and ER-NeRF.

ER-NeRF is trained on videos of a single individual, so a specific model needs to be replaced to render and obtain the correct results. It comes with pre-installed weights for Obama, which can be used directly with the following command:

python app_talk.py

MuseTalk has been integrated into Linly-Talker, enabling efficient preprocessing of MuseV-generated videos. Once preprocessed, these videos facilitate conversations at speeds that meet near real-time requirements, providing very fast performance. MuseTalk is now available within the WebUI.

To run the application, use the following command:

python app_musetalk.py
