Conversational AI avatars
LLM-powered digital humans that hold a natural spoken conversation — grounded in your content with RAG so they answer from your real knowledge, not a generic model.

What we build
AI avatars for installations, apps and training.
Museum & brand installations
Interactive avatar experiences for museums, exhibitions, retail and events. Meet Eva Here, created by artist Shavonne Wong, is an example of our Unity and visitor-tracking work in a public installation.
Onboarding & training assistants
AI avatar guides that onboard and train employees — built on the same instincts behind Work Spatial, our AI and XR onboarding platform with spatial UX.
Real-time digital humans
High-fidelity avatars with real-time lip-sync, text-to-speech, and speech-to-text — tuned so the voice, mouth, and facial motion stay in sync and feel alive.
Avatar integration for apps & XR
We embed avatars into your existing apps, websites, and XR experiences — running in WebGL, native, or on Meta Quest and Apple Vision Pro, wired to your own data and APIs.
Proof-of-concept sprints
4–6 week PoC sprints for teams who need a working avatar to pitch internal stakeholders. Fixed scope, fixed fee, a real digital human you can talk to at the end.
Virtual Verse Studio develops conversational AI avatars for museums, brands and enterprise applications. The work combines a 3D character, speech recognition, an AI conversation system, voice output and facial animation. We scope these together so the avatar fits the space and the people using it.
For artist Shavonne Wong's Meet Eva Here at ArtScience Museum in Singapore, we built a Unity-based interactive system using computer vision and body tracking. The project demonstrates our work on physical avatar interaction; its case study identifies the delivery scope. We also developed the MVP of Work Spatial, an AI and XR onboarding platform.
A useful brief identifies the audience, approved source material, languages, display or device, and actions the avatar can take. It should also define what happens when the avatar cannot answer, loses connectivity or needs to hand over to a person.
A focused pilot lets you test response time, answer quality and character design before commissioning a full installation or rollout. We select the rendering and voice tools around that brief and identify the ongoing hosting and AI service costs.
Agree what the pilot must demonstrate.
Before production, choose one visitor task and agree the device, source material and test conditions. Use these checks to define the pilot's acceptance criteria:
- An approved question — the avatar answers from the supplied material and gives the visitor a useful next step.
- A question outside its knowledge — it acknowledges the gap and offers an agreed fallback or human contact.
- An interruption or unavailable microphone — the visitor can recover and continue through the agreed alternative.
- A new visitor — the previous session ends and the experience returns to a clear starting state.
These are proposed checks for your pilot, not published performance results. Agree response-time and answer-quality thresholds after testing the intended setup.
Why us for AI avatars
Meet Eva Here: a museum avatar installation.

Meet Eva Here — Unity interaction for a museum installation
Meet Eva Here is an artwork by Shavonne Wong. Virtual Verse Studio developed the Unity-based interaction system, including computer vision, body tracking and avatar responses to visitors. It was exhibited at Singapore's ArtScience Museum. Explore the project film and delivery notes to see which parts of the installation we built.

From scoping call to a talking avatar
Discovery call
A free 30-minute conversation on your avatar's purpose, audience, brand voice, and where it lives — a kiosk, a large display, an app, the web, or XR.
Scope & proposal
A fixed-fee or milestone proposal within a week — avatar fidelity, the LLM and voice pipeline, knowledge grounding, and a clear pilot deliverable.
Avatar & conversation design
We design the avatar's look and rig, define its personality and guardrails, and ground it in a slice of your real content with RAG — delivered in 2–3 weeks.
Build & review sprints
Agile bi-weekly sprints wiring up speech-to-text, the LLM, text-to-speech, and lip-sync. You talk to live builds, and that feedback drives the next iteration.
Launch & support
Deployment to your venue, app, or web, tuning for latency and reliability in the real environment, and lifetime technical support as models and content evolve.

FAQ · questions
What XR buyers ask us
What is AI avatar development?
AI avatar development is the practice of building interactive digital humans that look, listen, and respond like a real person. It combines a real-time 3D or rendered avatar with conversational AI — speech-to-text to hear a visitor, a large language model to understand and reply, text-to-speech for a natural voice, and lip-sync animation so the mouth and face match the words. As an AI avatar development company, Virtual Verse Studio handles the full stack, from avatar art and rigging to the LLM logic and deployment.
Can you build a conversational AI avatar for our brand or museum?
Yes. We scope the character, voice, approved knowledge and deployment together. For museums and public spaces, we also plan input hardware and how sessions start and end. Our Meet Eva Here case study documents Unity and visitor-tracking work for artist Shavonne Wong; use a scoped pilot to evaluate conversational behaviour against your own content.
How do AI avatars handle real-time conversation?
A conversational AI avatar runs a real-time loop: speech-to-text transcribes what the person says, a large language model (such as Gemini or GPT) interprets it and generates a reply, text-to-speech turns that reply into a natural voice, and a lip-sync system drives the avatar's mouth and facial animation to match. We use retrieval-augmented generation (RAG) to keep the avatar grounded in your real content, and we tune the pipeline so the perceived response latency feels conversational rather than robotic.
How much does AI avatar development cost?
Cost depends on avatar fidelity, how the avatar is deployed, and how deep the conversational logic goes. A focused proof-of-concept avatar pilot typically lands in the mid-five figures, while a polished, branded installation or a fully integrated enterprise assistant with custom knowledge and integrations runs into six figures. We recommend a short PoC sprint first to validate the experience and the AI behaviour before committing to full production.
Can the avatar integrate with our existing app or website?
Yes. We integrate AI avatars into existing apps, websites, and XR experiences rather than forcing a separate product. The avatar can run in the browser via WebGL, embed inside a native or Unity app, or connect to your own backend, knowledge base, and APIs so it answers from your real data. Work Spatial — our AI plus XR onboarding platform — is an example of an AI-driven experience wired into a wider product flow.
Do you build avatars for XR, Vision Pro, or the web?
Yes. We build avatars for the browser with WebGL, for native and mobile apps, and for XR headsets including Meta Quest and Apple Vision Pro. The same conversational core — LLM, speech-to-text, text-to-speech, and lip-sync — drives the avatar across targets, and we adapt the rendering and interaction model to each platform. We have shipped real-time immersive work across Quest, HoloLens, and the browser.
How long does an AI avatar pilot take?
A proof-of-concept AI avatar pilot typically takes 4–6 weeks to reach a working, demonstrable experience — a real avatar you can talk to, grounded in a slice of your content. That gives stakeholders something concrete to evaluate before a full production build, which usually adds several more weeks depending on fidelity, integrations, and deployment target.
