Avatar & Zero-Shot Voice Cloning
Your Brand's Face and Authentic Voice Generated Once, Running Real-Time On-Device
A photoreal video persona paired with zero-shot neural voice cloning. Upload a single 5 to 30 second audio clip and reference photo to deploy an interactive digital human running locally at 60 FPS with zero cloud dependencies.
Photoreal Persona & Zero-Shot Voice Synthesis Pipeline
HS Global AI separates digital humans into two distinct, deterministic engineering pipelines: the visual video persona and the neural voice engine. The visual avatar displays seamless state transitions (idle, listening, thinking, speaking, and selfie pose) with smooth cross-fades so state changes never show jarring video cuts.
The voice engine uses zero-shot neural cloning. By uploading a single 5 to 30 second clean audio clip (WAV or MP3), the system normalizes the audio to 24kHz mono and pre-encodes the voice profile once at upload. From then on, the avatar speaks any sentence in any of our 29+ supported languages in your authentic voice synthesized 100% on-device with zero per-hour API fees.

Micro-Features & Engineering Detail
Real-Time Lipsync Generation
Mouth movement is generated on-device from audio phonemes as it is spokenβfaster than real time, ensuring speech never waits for video.
State-Driven Presence & Cross-Fades
The avatar visibly listens, thinks, and speaks with smooth cross-fade transitions between state clips rather than static looping videos.
Zero-Shot Voice Cloning
Requires only one 5β30 second clean audio clip. No studio recording sessions, GPU re-training runs, or per-minute voice API charges.
Gender-Correct Default Fallback
Avatars deployed without a custom audio clip automatically select a gender-matched default voiceβnever a mismatched voice profile.
Expressive Speech Tags
Supports natural breath, pause, and laugh tags in English speech generation for human-like conversational inflections.
Per-Avatar Voice Storage
Each avatar carries its own checksum-verified voice profile. Switching characters on screen updates the voice engine instantly.
Multi-Avatar Character Switching
A single kiosk screen can store multiple distinct character personas and switch between them instantly upon visitor selection.
Package Integrity Verification
Every avatar package is checksum-verified at installation, ensuring approved brand presentation runs reliably without corruption.
How It Works End-to-End
Upload Photo & 10s Voice Clip
Provide 1 high-resolution front-facing photo or video reference plus a 5β30 second clean voice recording.
Cloud Pipeline Generates State Package
Our automated pipeline generates the 3D facial mesh, state video clips (idle, listening, thinking, speaking), and pre-encodes the 24kHz voice profile.
Deploy Package to Local Hardware
Download the self-contained persona package (.zip) directly onto your local GPU kiosk or Hologram Box.
Real-Time On-Device Execution
The avatar listens, thinks, speaks, and switches languages on-device with Low-Latency lip-sync and 0ms cloud dependency.

Frequently Asked Questions
How long does voice cloning take to set up?
Voice cloning takes under 5 minutes. You upload a 5 to 30 second clean audio recording, and our system pre-encodes the neural voice profile automatically.
Does the voice cloning require cloud connections during operation?
No. Once the voice profile is encoded into the avatar package, all neural voice synthesis runs 100% locally on your device's GPU with zero internet connection required.
Can one kiosk host multiple different avatars?
Yes! A single kiosk can store multiple persona packages and allow visitors to switch between characters on screen instantly.
What happens if I don't provide a voice recording?
The platform automatically assigns a high-quality, gender-correct neural fallback voice matched to your avatar's persona.
