Introduction

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.

The system architecture of multimodal humanโ€“computer interaction.

Setup Environment

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

# PyTorch Installation Method 2: Pip Installation
pip install torch==1.12.1+cu113 torchvision==0.13.1+cu113 torchaudio==0.12.1 --extra-index-url https://download.pytorch.org/whl/cu113

conda install -q ffmpeg # ffmpeg==4.2.2

pip install -r requirements_app.txt

If you want to use models like voice cloning, you may need a higher version of PyTorch. However, the functionality will be more diverse. You may need to use CUDA 11.8 as the driver version, which you can choose.

conda create -n linly python=3.10  
conda activate linly

pip install torch==2.1.0 torchvision==0.16.0 torchaudio==2.1.0 --index-url https://download.pytorch.org/whl/cu118

conda install -q ffmpeg # ffmpeg==4.2.2

pip install -r requirements_app.txt

# Install dependencies for voice cloning
pip install -r VITS/requirements_gptsovits.txt

Next, you need to install the corresponding models. You can download them using the following methods. Once downloaded, place the files in the specified folder structure (explained at the end of this document).

# Download pre-trained models from HuggingFace Or ModelScope

LLM Model Selection

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)

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.

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.

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

The folder structure of the weight files is as follows:

  • Baidu (็™พๅบฆไบ‘็›˜): You can download the weights from here (Password: linl).
