Offline AI Digital Human Software for Enterprise Presence.
DIHUAVA is an enterprise offline AI digital human software platform developed by HS Global AI. It powers interactive 3D avatars that converse naturally, query proprietary knowledge with on-device RAG, speak 29+ global languages, and operate locally on dedicated GPU hardware across interactive kiosks, 3D hologram boxes, and spatial displays—running on-device by default with optional cloud-management configurations.
Local Speech, Voice Cloning, Document RAG & 3D Lip Sync Active
What Is Offline AI Digital Human Software?
Offline AI digital human software is an on-premise application that runs conversational 3D avatars locally on dedicated computer hardware without requiring continuous cloud connectivity or external API streaming. Developed by HS Global AI, the DIHUAVA platform executes automatic speech recognition (ASR), on-device document intelligence (RAG), conversational LLM reasoning, neural voice synthesis (TTS), and real-time facial lip-sync directly on local GPU hardware. This architecture keeps proprietary corporate documents private, eliminates latency from cloud round-trips, and ensures continuous autonomous operation in physical environments.

On-Device Processing and Offline Deployment
DIHUAVA is an on-device AI digital human platform engineered for offline enterprise deployment. Speech recognition, document retrieval (RAG), conversational LLM reasoning, voice synthesis, and 3D avatar rendering run locally on physical workstations—eliminating continuous cloud streaming dependencies during daily operations, while optional network connectivity remains available for initial installation, software updates, centralized fleet oversight, or mobile QR sharing.
Digital Avatar Renderer
3D facial mesh rendering, real-time lip synchronization, micro-expressions, posture control, and persona identity management.
29+ Multilingual Speech Engine
Real-time speech recognition & synthesis across 29+ global languages and major regional dialects with instant auto-switch.
Knowledge & Catalog RAG Engine
Air-gapped local vector indexer with cross-encoder reranking, multi-column CSV catalog import, and auto vocabulary generation.
Low-Latency Edge Pipeline
High-speed local stream architecture delivering end-to-end conversational response times with low latency for fluid dialogue.
Computer Vision & Face Tracking
Wide-angle camera face tracking, eye-gaze direction sensing, visitor posture tracking, and presence detection array.
100% Offline Air-Gapped Security
Zero cloud internet dependency, enterprise privacy compliance, encrypted local vector storage, and physical edge workstation hosting.
Spatial & Hologram Display Controller
Synchronized output drivers for 3D Hologram Boxes, volumetric optical spatial displays, touch kiosks, and multi-screen arrays.
Hardware Edge Acceleration
Optimized for local NVIDIA RTX GPU acceleration with unified VRAM execution across speech, LLM, and rendering models.
How DIHUAVA Powers Offline Conversational AI Avatars
An integrated local edge pipeline powering responsive, face-to-face avatar interactions without public cloud round-trips or third-party data transmission.
Understand
Voice input, documents, product catalogs, and visitor questions are processed locally on the edge.
Think
The local AI engine retrieves relevant knowledge and generates a grounded response with strict guardrails.
Speak
Text is converted to natural speech in the visitor's detected language using voice cloning models.
Interact
The digital human moves, speaks with lip sync, and presents visual cards on the display in real time.
Multilingual AI Avatar Software & Modular Features
Comprehensive capabilities for enterprise multilingual AI avatar software: on-device speech across 29+ languages, document RAG, CSV-driven product recommendations, interactive selfie compositing, and live cartoon face tracking.
Selfie With Avatar
Instant On-Device Photo Compositing
Visitors tap Selfie on the display to capture a photo standing beside the AI Avatar. Features deterministic real-time face-scale matching, 6 creative filters (Realistic, Original, B&W, Vivid, Warm, Cool), and optional QR phone sharing with 24-hour auto-expiring links.
Live Character Experience
Real-Time Cartoon Face Mode
A real-time camera-driven cartoon rendering mode where a visitor's live facial expressions (smiles, blinks, head turns) deform a stylized character skin directly onto their face in real time with ultra-low latency.
AI Product Catalog
CSV-Driven Recommendation Engine
Converts product catalog CSVs into an intelligent spoken recommendation system. Displays interactive product cards, price filtering, and automatic audio-visual synchronization so the avatar only discusses products currently on screen.
Enterprise Knowledge RAG
On-Device PDF RAG with Reranking
Ingest custom corporate PDFs, CSVs, TXT, and Markdown files directly onto the local device. An on-device relevance reranker scores passages before generating grounded responses with zero data leaving your premises.
Multilingual Engine & Voice Cloning
29+ Global Languages & Brand Voice Matching
Full on-device speech recognition, voice synthesis, and translation across 29+ global languages, including regional accents and automatic per-persona voice cloning.
Custom Avatar Studio
Personalized Digital Human Personas
Choose from professional digital avatars or build custom 3D character avatars with customized brand attire, personalized acoustic profiles, unique conversational tone, and corporate styling.
Brain Clone (In Dev)
Digital Persona Knowledge Twin
A long-term digital persona preservation architecture designed to index personal histories, philosophies, corporate executive knowledge bases, and distinctive speech patterns into an interactive digital twin.
AI Digital Human for Kiosks and Interactive Displays
Deploy enterprise digital human software across high-traffic physical touchpoints—optimizing each AI digital human for freestanding touchscreen kiosks, 3D Hologram Boxes (55″–86″), and Glasses-Free Spatial Displays in smart retail, healthcare guidance, banking, and corporate reception.

Custom 3D character mesh, corporate wardrobe, custom voice cloning reference, and branded interaction style.
Custom Enterprise Persona Package
Appearance
Create a digital human avatar aligned with your brand visual identity and attire.
Voice
Use multilingual voices or a cloned corporate ambassador voice profile.
Personality
Configure communication tone, empathy level, and domain response style.

Embedded GPU Hardware
Operates on compact industrial workstations or embedded PCs inside the kiosk enclosure. An 8GB VRAM GPU provides a baseline recommendation for smooth local inference.
Autonomous Offline Reliability
Core dialogue, speech synthesis, and facial lip-sync execute 100% on-device by default, ensuring uninterrupted visitor assistance during venue network outages.
Offline Digital Human Platform vs. Cloud-Based Alternatives
Understand how local on-device processing compares with traditional cloud-dependent avatar services in privacy, network dependency, latency, and operational cost.
| Capability | DIHUAVA Local Platform | Typical Cloud Architecture |
|---|---|---|
| Data Privacy & Data Residency | Local on-device execution; voice input and document queries remain on premises without mandatory cloud transmission | Queries streamed to third-party cloud servers with external logging and multi-tenant residency |
| Network Dependency | Operates offline locally; continuous broadband is not required for daily autonomous avatar interactions | Requires continuous high-bandwidth internet connectivity; sessions fail during network outages |
| Conversational Latency | Local GPU inference avoids cloud network round-trips and external API queue delays | Subject to variable WAN latency, router jitter, and public cloud queue backpressure |
| Licensing & Operating Cost | On-premise deployment can avoid recurring cloud API usage charges. Software licensing, maintenance, updates, and support terms depend on the agreed commercial package. | Unpredictable recurring expenses scaling linearly with customer conversation minutes and token volume |
| Deployment Form Factors | Native hardware driver integration for interactive touch kiosks, 3D hologram boxes, and spatial displays | Primarily web browser embeds with limited native peripheral hardware support |
