See Real Human Event Hosts in Action
AI webinar and event hosts use real human avatars—actual people filmed on location—powered by advanced lip-sync and voice synthesis technology. They look, sound, and move like real presenters, complete with natural expressions and multilingual delivery.
Unlike CGI avatars (computer-generated faces), LipSynthesis uses real people filmed in professional settings, then digitized for AI-powered video generation. The result? Hosts that feel authentic, relatable, and trustworthy—not robotic or "too perfect."
Choose your host – Select from hundreds of real human avatars representing diverse demographics, professions, and settings (or create a custom avatar with your own face)
Select voice – Choose a voice with accurate lip-sync, or upload your own audio
Write your script – Type what you want your host to say
Generate your video – Create polished event segments or full presentations in hours, not weeks
No cameras. No studios. No retakes.

See How Custom Avatars Work for Personal Branding
Not all AI avatars are created equal. Most platforms use CGI avatars (computer-generated faces) that can trigger the "uncanny valley" effect—where something looks almost human, but not quite, causing discomfort and distrust.
LipSynthesis uses real human avatars—actual people filmed on location, then digitized for AI video generation.
Factor | CGI Avatars | Real Human Avatars (LipSynthesis) |
|---|---|---|
Trust | Can feel artificial or "too perfect" | Authentic expressions build immediate trust |
Relatability | Often polished to the point of sterility | Natural imperfections feel human |
Backgrounds | Green screen or generic environments | Real offices, homes, outdoor settings |
Audience Response | May trigger skepticism | Viewers recognize and relate to "real" |
The data: 88% of consumers say authenticity is important when deciding which brands they like and support (Stackla, 2019). For webinars and events where trust drives engagement, real human avatars win.
