🚀 Recommendation: Option A (OpenAI Realtime + LiveKit)
This path offers the most "native" conversational experience (low latency, interruptible) suitable for a "Jarvis-like" interface.
Executive Summary
Three main architectures were evaluated for enabling direct voice communication between Optimus and Agent Zero.
Option A: The "Native" Experience (Recommended)
Stack: OpenAI Realtime API + LiveKit
- Pros: Lowest latency (audio-to-audio). Natural interruptions. Emotional range.
- Cons: Higher cost (~$0.06/min). Requires custom frontend.
- Verdict: Best for high-quality interaction.
Option B: The "High Quality" Experience
Stack: ElevenLabs Conversational AI
- Pros: Superior voice realism (5000+ voices). Easy widget setup.
- Cons: Higher latency than Realtime API. Less logic flexibility.
- Verdict: Good for "human-sounding" chat, less for complex tasks.
Option C: The "Telephony" Experience
Stack: Retell AI + Twilio
- Pros: Works via standard phone call. No app needed.
- Cons: Lower audio quality (8kHz phone line).
- Verdict: Best for on-the-go access without data/web.
