Welcome to our Digital Human solution showcase. Powered by NVIDIA's AI technologies, including ACE, RIVA, and NeMo RAG, this demo features an advanced, lifelike and interactive AI virtual assistant. Our digital human can execute natural conversations and perform other human-like experiences like answering questions, providing recommendations, and guiding users through complex processes.

• Initiating the demo: The facilitator uses a presentation clicker to start. The digital human/avatar is displayed on the screen, introducing itself and greeting the user.
• User engagement: The user initiates a conversation with the digital human/avatar through voice input.
• Dynamic interaction: Driven by NeMo, the digital human/avatar provides contextually accurate responses, with a knowledge base offering sample questions or prompts.
• Realistic presentation: Responses are enriched with ACE-enhanced expressions and Riva-generated speech, creating lifelike interactions.
• Task execution: The avatar handles detailed inquiries, similar to interactions in a drive-thru scenario.

How was the interactive avatar created? What are the components?

• NVIDIA Avatar Cloud Engine (ACE): Brings digital humans to life with generative AI, covering speech, vision, intelligence, animation, and lifelike appearance.
• NVIDIA Riva: Provides multilingual speech and translation microservices for real-time conversational AI.
• NVIDIA NeMo RAG: Enhances LLMs with retrieval-based methods for accurate, contextually relevant responses.
• Broader NVIDIA Stack: Includes GPUs and AI frameworks, providing the computational power and efficiency needed for real-time performance and scalability.
