Artificial Intelligence (AI) is revolutionizing how we create and interact with virtual beings. What was once a sci-fi fantasy is now a real-world innovation: AI-generated digital humans that can move, smile, talk, and react in real-time. From social media influencers to brand avatars and virtual assistants, AI-powered digital people are reshaping industries from marketing to entertainment.
In this guide, we’ll explore how to use AI to create a lifelike digital person who can move, smile, and engage with people—just like a real human.
What Is a Digital Person or AI Human?
A digital person, sometimes referred to as an AI human or virtual human, is a computer-generated character powered by AI algorithms. These virtual beings are designed to look and behave like real people. Thanks to advancements in deep learning, computer vision, and natural language processing (NLP), digital persons can now:
- Smile naturally
- Move their heads and bodies realistically
- Speak with synced lip movements
- React to voice commands or prompts
- Express emotions through facial gestures
Why Create a Digital Person?
Here are just a few reasons why people and businesses are turning to AI humans:
- Influencers and content creators use them to post content 24/7 without showing their face.
- Brands use them as customer service avatars or spokespersons.
- Educators use them as virtual tutors.
- Game developers and filmmakers use them for storytelling and interactive media.
- Startups use AI humans for scalable marketing.

- Choose a background (studio, outdoor, virtual scene)
This is where your AI human becomes unique. You can make a digital person that looks like you, your ideal influencer, or a fictional character.
- Add Smile and Facial Expressions
Advanced platforms use facial animation technology and GANs (Generative Adversarial Networks) to animate facial movements. You can:
- Adjust smile intensity (subtle to big grin)
- Trigger blinking, eyebrow raising, or head tilts
- Synchronize expressions with speech or emotion
Platforms like APOB AI let you preview how your digital person will smile while talking, adding realism to your avatar.
- Animate Movement and Body Language
To make the digital person move, you can:
- Add gestures (hand waving, head nodding, shoulder movements)
- Use preset animations for speaking, greeting, or presenting
- Upload a video or audio file to generate synced body movements
Some platforms even let you control movements with your own webcam (motion capture).
- Add Voice and Dialogue
The last step is making your digital human talk:
- Upload your own voice or choose from AI-generated voices
- Input text to be spoken (text-to-speech)
- Match lip-sync with the voice for realism
With multi-language support, your AI human can speak fluent English, Spanish, Mandarin, and more—perfect for international audiences.
