In this article：

What Are Digital Humans?

A digital human is a computer-generated human-like character powered by artificial intelligence. These entities can speak, move, express emotions, and interact with users through text, voice, or video.

Digital humans combine AI-generated visuals, speech synthesis, and conversational intelligence to simulate realistic human communication in digital environments.

Digital Humans vs Virtual Humans vs Artificial Humans

Digital Humans: Realistic AI-generated human characters for communication and media.

Virtual Humans: Broader term including avatars, game characters, and VR personas.

Artificial Humans: Conceptual term describing AI-driven humanoid entities mimicking human behavior.

All of them represent the evolution of human digital identity and AI-human interaction.

How Digital Humans Work

Digital humans rely on three technical layers:

1 Visual Layer

Neural rendering models generate realistic faces, expressions, and body movements.

2 Voice Layer

Text-to-speech (TTS) and voice cloning create natural-sounding speech.

3 Intelligence Layer

Large language models (LLMs) provide conversation, reasoning, and personalization.

Methods to Create a Digital Human

There are multiple ways to build digital humans, from no-code AI tools to professional production pipelines.

1 AI Digital Human Generators (Fastest & No-Code)

AI generators are the easiest way to create a digital human. They automate avatar creation, voice synthesis, and facial animation.

How to Create a Digital Human with ChatArt (Step-by-Step)

ChatArt is an AI platform that allows users to create digital humans, AI avatars, and talking videos using text and images.

Step 1Open ChatArt: Go to: https://app.chatartpro.com/
Step 2Select "Text to Video"/ Image-to-Video
Step 3Pick a model (e.g., Veo, Sora, Wan, Seedance)
Step 4Write a Prompt for Your Digital Human

Example prompt:

"A realistic digital human presenter, professional studio lighting, speaking confidently, cinematic camera movement."

Step 5Customize Settings: Choose aspect ratio, resolution, and video length. Adjust realism level, style, and camera motion
Step 6Generate and Download: Click Generate and wait for the AI to create your digital human video

Pros

  • Fastest workflow – generate videos in minutes
  • Supports cinematic AI models (e.g., Veo, Sora, Wan, Seedance)
  • Highly scalable for marketing and social media content
  • Beginner-friendly with no technical skills needed

Cons

  • Some models require credits or paid plans
  • Limited fine-grained facial customization compared to 3D modeling

2 Modeling and Animation (Professional Pipeline)

Professional studios create digital humans using 3D software and animation workflows.

Step-by-Step Workflow for 3D Digital Humans

Step 1 Create a 3D Human Model: Use tools like Blender, Maya, or ZBrush. Sculpt face, body, skin, and textures.
Step 2 Rig the Character: Add facial and body rigs for movement. Create blend shapes for expressions
Step 3 Record Motion Capture: Use mocap suits or facial capture cameras. Record gestures, facial expressions, and body movements
Step 4 Animate and Simulate: Apply motion data to the 3D model. Add physics, hair simulation, and cloth simulation
Step 5 Render the Digital Human: Use Unreal Engine or offline renderers. Export video, game assets, or real-time avatars

This method is used in films, AAA games, and metaverse projects but requires high expertise and cost.

Pros

  • Highest realism and customization
  • Full control over face, body, hair, clothing, and environment
  • Supports real-time interaction in games and metaverse

Cons

  • Extremely time-consuming (weeks or months)
  • Requires advanced technical skills and expensive software

3 Digital Twin Creation (Real Human Replication)

A digital twin is a virtual replica of a real person.

Step-by-Step Process to Create a Digital Twin

Step 1 Capture Visual Data: Record high-resolution photos or videos. Use multiple angles and lighting setups
Step 2 Capture Voice Data: Record speech samples for voice cloning. Ensure consent and legal compliance
Step 3 Train AI Models: Use AI to learn facial movements and voice patterns. Generate a personalized digital human model
Step 4 Integrate AI Intelligence: Connect the avatar to conversational AI or knowledge bases. Enable real-time interaction
Step 5 Deploy the Digital Twin: Use in training, marketing, corporate communication, or personal AI assistants. Some AI tools, including ChatArt, allow users to upload reference images or videos to simplify digital twin creation.

Pros

  • Highest identity accuracy – replicates a real person’s face, voice, and mannerisms
  • Strong personal branding – ideal for CEOs, influencers, educators, and public figures

Cons

  • Privacy and consent risks – requires explicit legal permission from the real person

4 Conversational AI Integration (Interactive Virtual Humans)

Digital humans become truly powerful when combined with AI chat systems.

Step-by-Step Workflow for Interactive Digital Humans

Step 1Create or Select an Avatar: Use AI avatar tools or 3D models.
Step 2Connect to an AI Language Model: Integrate with LLMs for conversation and reasoning.
Step 3Build a Knowledge Base: Upload documents, FAQs, or company data. Enable contextual responses
Step 4Add Speech Recognition and TTS: Allow users to speak to the digital human. Generate real-time spoken responses
Step 5Deploy on Platforms: Website, mobile app, VR, kiosks, or metaverse environments

Pros

  • Good for explainer videos and corporate training
  • Multilingual AI voices available

Cons

  • Limited avatar customization
  • Less realistic than generative AI video models

Use Cases of Digital Humans

Marketing and Content Creation

Digital humans act as AI presenters, brand ambassadors, and explainer video hosts.

Customer Support

Virtual humans provide 24/7 multilingual customer service.

Education and Training

AI instructors deliver personalized learning and corporate onboarding.

Entertainment and Metaverse
