2023.12 Update 📆

Users can upload any images for the conversation

2024.01 Update 📆📆

• Exciting news! I've now incorporated both the powerful GeminiPro and Qwen large models into our conversational scene. Users can now upload images during the conversation, adding a whole new dimension to the interactions.
• The deployment invocation method for FastAPI has been updated.
• The advanced settings options for Microsoft TTS have been updated, increasing the variety of voice types. Additionally, video subtitles have been introduced to enhance visualization.
• Updated the GPT multi-turn conversation system to establish contextual connections in dialogue, enhancing the interactivity and realism of the digital persona.

2024.02 Update 📆

• Updated Gradio to the latest version 4.16.0, providing the interface with additional functionalities such as capturing images from the camera to create digital personas, among others.
• ASR and THG have been updated. FunASR from Alibaba has been integrated into ASR, enhancing its speed significantly. Additionally, the THG section now incorporates the Wav2Lip model, while ER-NeRF is currently in preparation (Coming Soon).

Linly-Talker is an intelligent AI system that combines large language models (LLMs) with visual models to create a novel human-AI interaction method. It integrates various technologies like Whisper, Linly, Microsoft Speech Services and SadTalker talking head generation system. The system is deployed on Gradio to allow users to converse with an AI assistant by providing images as prompts. Users can have free-form conversations or generate content according to their preferences.

To install the environment using Anaconda and PyTorch, follow the steps below:

conda create -n linly python=3.10
conda activate linly

# PyTorch Installation Method 1: Conda Installation (Recommended)
conda install pytorch==1.12.1 torchvision==0.13.1 torchaudio==0.12.1 cudatoolkit=11.3 -c pytorch

To implement ASR (Automatic Speech Recognition) using OpenAI's Whisper, you can refer to the specific usage methods provided in the GitHub repository: https://github.com/openai/whisper

The speech recognition performance of Alibaba's FunASR is quite impressive and it is actually better than Whisper in terms of Chinese language. Additionally, FunASR is capable of achieving real-time results, making it a great choice. You can experience FunASR by accessing the FunASR file in the ASR folder. Please refer to https://github.com/alibaba-damo-academy/FunASR for more information.

bash scripts/sadtalker_download_models.sh  

Baidu (百度云盘) (Password: linl)

If downloading from Baidu Cloud, remember to place it in the checkpoints folder. The model downloaded from Baidu Cloud is named sadtalker by default, but it should be renamed to checkpoints.

Digital persona generation can also utilize Wav2Lip (ACM 2020). For detailed information, refer to https://github.com/Rudrabha/Wav2Lip.

Before usage, download the Wav2Lip model:

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.

In the app.py file, tailor your model choice with ease.

# Uncomment and set up the model of your choice:

# llm = LLM(mode='offline').init_model('Linly', 'Linly-AI/Chinese-LLaMA-2-7B-hf')
# llm = LLM(mode='offline').init_model('Gemini', 'gemini-pro', api_key = "your api key")
# llm = LLM(mode='offline').init_model('Qwen', 'Qwen/Qwen-1_8B-Chat')

# Manual download with a specific path
llm = LLM(mode=mode).init_model('Qwen', model_path)

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 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.

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.

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)

# WebUI
python webui.py

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
