Digital Human Intelligent Dialogue System - Linly-Talker — 'Interactive Dialogue with Your Virtual Self'
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).
- I have incorporated the GPT-SoVITS model, which is a voice cloning method. By fine-tuning it with just one minute of a person's speech data, it can effectively clone their voice. The results are quite impressive and worth recommending.
- I have integrated a web user interface (WebUI) that allows for better execution of Linly-Talker.

- Digital Avatar Conversational System - Linly-Talker —— "Digital Persona Interaction: Interact with Your Virtual Self”
Linly-Talker is an innovative digital human conversation system that integrates the latest artificial intelligence technologies, including Large Language Models (LLM) 🤖, Automatic Speech Recognition (ASR) 🎙️, Text-to-Speech (TTS) 🗣️, and voice cloning technology 🎤. This system offers an interactive web interface through the Gradio platform 🌐, allowing users to upload images 📷 and engage in personalized dialogues with AI 💬.
The core features of the system include:
- Multi-Model Integration: Linly-Talker combines major models such as Linly, GeminiPro, Qwen, as well as visual models like Whisper, SadTalker, to achieve high-quality dialogues and visual generation.
- Multi-Turn Conversational Ability: Through the multi-turn dialogue system powered by GPT models, Linly-Talker can understand and maintain contextually relevant and coherent conversations, significantly enhancing the authenticity of the interaction.
- Voice Cloning: Utilizing technologies like GPT-SoVITS, users can upload a one-minute voice sample for fine-tuning, and the system will clone the user's voice, enabling the digital human to converse in the user's voice.
- Real-Time Interaction: The system supports real-time speech recognition and video captioning, allowing users to communicate naturally with the digital human via voice.
- Visual Enhancement: With digital human generation technologies, Linly-Talker can create realistic digital human avatars, providing a more immersive experience.
The design philosophy of Linly-Talker is to create a new form of human-computer interaction that goes beyond simple Q&A. By integrating advanced technologies, it offers an intelligent digital human capable of understanding, responding to, and simulating human communication.

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:
-
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.
-
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.pyThe 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.pyThe folder structure of the weight files is as follows:
Baidu (百度云盘): You can download the weights from here (Password:linl).huggingface: You can access the weights at this link.modelscope: The weights will be available soon at this link.
