VR Intelligent Assistant

Project Overview

Developed a proof-of-concept VR-based intelligent assistant system integrating real-time speech processing, advanced language models, and avatar animation. The system provides immediate access to corporate policies and information through an immersive metaverse interface, achieving sub-second response times for enhanced user experience.

Technical Implementation

• Virtual Reality Environment: Engineered using Unity Engine with custom shaders and optimized avatar animations. Implemented lip-sync system for natural speech animation.
• AI and Natural Language Processing: Leveraged GPT-4 Turbo for advanced language understanding and response generation, integrated with a custom RAG system using ChromaDB and Azure Blob Storage for efficient information retrieval from corporate documentation.
• Audio Processing Pipeline: Developed a streamlined audio processing system incorporating speech-to-text conversion, context-aware response generation, and text-to-speech synthesis with lip synchronization, all optimized for sub-second latency.

System Architecture

• Real-time audio capture and streaming using Unity's audio system.
• Parallel processing of speech-to-text and context retrieval.
• Optimized RAG system with pre-indexed corporate documentation.

Performance Metrics

• End-to-end response time: < 1 second
• Speech recognition accuracy: 95%+

Impact and Future Implementation

• Presented at Corporate Innovation Conference 2024, receiving positive feedback from industry leaders.
• Under evaluation by HR department for integration into new employee onboarding process.
