This research introduces a vital new benchmark for evaluating voice agents using real human speech, complete with natural disfluencies like stuttering or self-corrections. It is exciting to see top-tier models like GPT-Realtime and Gemini Live 3.1 being pushed to handle complex, multi-step tool use, moving the industry closer to truly conversational AI. The focus on 'full-duplex' capabilities—listening and thinking while speaking—marks a significant step forward in creating seamless human-computer interactions.
Key Takeaways
- •GPT-Realtime ranks highest for accuracy and avoiding awkward interruptions during conversation.
- •Gemini Live 3.1 offers the fastest response speeds, though it sometimes misses turn-taking cues.
- •The benchmark uses real human audio with natural disfluencies, challenging agents to handle messy, realistic speech.
