What actually makes an AI agent sound human
Latency, empathy, and knowing when to stop talking. The details that separate a helpful agent from an obvious bot.
The uncanny valley of voice AI isn't about the voice itself — modern synthesis is excellent. It's about timing, interruption handling, and empathy.
Latency is everything. A natural conversation has sub-second turn-taking. An agent that pauses for two seconds before every reply feels robotic no matter how good the voice is.
Equally important is graceful interruption: real people talk over each other, change their minds, and trail off. An agent that can be interrupted — and recover — feels alive.
Finally, the best agents know their limits. Confidently handing off to a human, with full context, beats faking an answer every single time. Knowing when to stop talking is a feature.
