AI-Native Application Development

AI Video Avatar Solution Development

We build real-time AI avatar systems with sub-200ms lip-sync latency — powering customer-facing video bots, personalised training delivery, and automated communication at scale. Photorealistic. White-labelled. On-prem GPU deployable.

Avatar Capabilities
  • Real-time lip-sync with sub-200ms audio-to-video latency
  • Custom brand avatar from 10–15 min reference video
  • Multilingual voice cloning — 20+ languages
  • Emotion and expression control API
  • WebRTC stream output — drops into any video call
  • Async batch video generation via REST API
  • On-premise GPU deployment option (A100 / H100)

How It Works

Avatar Creation from Reference Video

A 10-15 minute reference video of the subject is processed to extract facial geometry, expression range, and appearance data. The avatar model is trained in 24-48 hours and validated against naturalness benchmarks before delivery.

Voice Cloning & Multilingual Synthesis

A 30-second voice sample is sufficient for voice cloning via XTTS v2 or ElevenLabs. The cloned voice can speak in 20+ languages while preserving the original speaker’s tone and cadence.

Real-Time Rendering & WebRTC Output

At runtime, the TTS audio stream drives the lip-sync model in real-time. The rendered video is encoded and injected as a WebRTC video track — plugging into any video call, platform, or embedded player without additional integration work.

What We Build

Custom Avatar Creation

Photorealistic digital human from a short reference video — with natural head movement, blinks, and expression variance built in.

Voice Cloning

30-second voice sample → full multilingual voice clone. Preserves tone and cadence across 20+ languages.

Real-Time WebRTC Output

Avatar rendered as a live WebRTC video track. Plugs directly into Samvyo rooms or any WebRTC endpoint with no additional integration.

Batch Video Generation

REST API for async personalised video at scale — 1,000+ personalised outreach or training videos per hour.

Emotion Control API

Programmatically set avatar emotion state (neutral, empathetic, authoritative) based on LLM conversation context.

On-Prem GPU Pipeline

SadTalker / MuseTalk / Wav2Lip containerised for A100/H100 on-site. Zero cloud dependency for regulated deployments.

CentEdge vs The Alternative

Third-Party Avatar APIs (HeyGen, Synthesia, D-ID)
  • All video processed on vendor's cloud servers
  • Per-video pricing — expensive at production scale
  • Generic avatars — not your brand's face
  • No real-time WebRTC output option
  • No on-premise GPU deployment option
CentEdge Custom Avatar Platform
  • On-prem GPU option — video never leaves your servers
  • One-time build — unlimited video generation included
  • Your brand's actual face, voice, and expressions
  • Real-time WebRTC track injection into any platform
  • Full on-premise deployment on A100/H100 hardware

Frequently Asked Questions

K
L
How photorealistic is the AI avatar?

Realism depends on the quality of the reference video and the rendering model used. With a well-lit, high-resolution reference and state-of-the-art models like MuseTalk or SadTalker, the output is photorealistic with natural-looking blinks, subtle head movements, and expression variance. For production deployments, CentEdge validates the output against naturalness benchmarks and iterates with you before go-live.

K
L
How long does it take to create a custom avatar?

Reference video capture takes 10-15 minutes. Training and validation typically takes 24-48 hours. Post-training adjustments and voice clone validation add another 24 hours. Total avatar creation timeline from reference video to approved production avatar is typically 3-5 business days.

K
L
What GPU hardware is required for on-premise deployment?

Real-time avatar rendering requires at minimum an NVIDIA A100 or H100 GPU for sub-200ms latency at production quality. For lower-quality or cached-response deployments, an RTX 4090 is sufficient. CentEdge sizes the GPU recommendation based on your expected concurrent session count and target quality level. The full inference stack is containerised and runs on standard Ubuntu with CUDA drivers.

K
L
Can the avatar speak multiple languages with the same voice?

Yes. The voice cloning model (XTTS v2) generates the cloned voice in 20+ languages from a single 30-second sample, preserving the speaker's tone, pace, and prosody across languages. This is particularly valuable for multilingual customer communication — the same brand avatar can speak English, Hindi, Tamil, and Spanish with a consistent voice identity.

K
L
How does the avatar integrate with an existing video calling platform?

The avatar is rendered as a standard WebRTC video track. This track can be injected into any WebRTC-based platform — Samvyo, Zoom SDK, a custom conferencing platform, or a browser-based video call — as a virtual camera input. No changes to the host platform are required. For batch video generation, a REST API delivers MP4 files directly.
