1. Listening.
Speech recognition and turn-taking interpret what a person says, handling interruptions naturally.
Guide
Conversational AI avatars, explained.
A plain-English guide to real-time digital humans - what they are, how they work, and where they earn their place.
The basics
What is a conversational AI avatar?
A conversational AI avatar is a photorealistic digital human that can listen, understand and respond in real time. Unlike a pre-recorded video or a static figure, it holds a genuine back-and-forth: a person speaks, and the avatar answers - face to face, in conversation.
When that avatar is displayed at life size in a physical unit, it creates the impression of a real presence in the room. That's the experience Zigg.ai delivers.
The four layers
How they work.
The whole loop happens in under a second, which is what makes the conversation feel real rather than laggy.
2. Thinking.
A language model generates a response - ideally grounded in approved source material and within set boundaries.
3. Speaking.
Text-to-speech produces a natural voice, in the right language and accent.
4. Appearing.
A real-time avatar model renders the face with accurate lip-sync and expression. Zigg.ai uses Anam's CARA model for this layer.
The format spectrum
Avatars vs older "hologram" experiences.
Static displays
Look impressive but can't respond.
Pre-recorded / looping video
Plays the same thing regardless of who's watching.
Live telepresence
Streams a real person - powerful, but scheduled and one-off.
Conversational AI avatars
Autonomous and always-on: a two-way conversation, any time.
Where they fit
Where they're used.
Events and exhibitions, retail and brand activations, corporate lobbies, onboarding and executive twins, museums, heritage and education, hospitality concierges, sports fan engagement.
Buying criteria
How to choose one.
Is it truly real-time?
Look for sub-second response, not a delay.
Is it grounded?
Answers should come from approved sources, with boundaries you control.
What does it really cost to run?
Real-time avatars are billed by the second - ask how idle time is handled. Zigg.ai only runs a live session when a visitor is present.
Who supports it?
A venue-grade deployment needs delivery, support and maintenance - not just a shipped box.
How fast can it change?
The best platforms let you swap characters in seconds.
