You're building an application utilizing NVIDIA ACE to create interactive virtual assistants. The goal is to have the assistant respond to user queries in a natural and contextually relevant way. Which of the following choices, when implemented together, would significantly contribute to achieving this objective?
Correct Answer: A
Natural and contextually relevant responses require accurate speech recognition, a capable LLM, and a dialogue management system to track context. Riva provides the speech components. A domain-specific LLM improves accuracy. Dialogue management enables coherent conversations. High-fidelity rendering (B) is secondary. Pre-trained LLMs (C) might lack domain expertise. Rule-based systems (D) are inflexible. Sacrificing accuracy for latency (E) hurts the user experience.
