AI Analysis — Deep Dive

Voice AI is finally good enough

Back to AI calling agents & call analysis
AI Calling Agents

The uncanny valley closed in 2024. Routine calls are now table stakes for voice AI.

Context

Latency under 500ms, natural-sounding voices, real interruption handling — modern voice agents (Vapi, Retell, OpenAI Realtime) cross the uncanny valley for routine calls. They never sleep, never have a bad day, and they're fluent in multiple languages.

What made it cross the line

Sub-500ms latency, natural turn-taking, interruption handling, expressive voices (ElevenLabs/OpenAI Realtime), and orchestration platforms (Vapi, Retell) that wire it all together. Together they hit the threshold where customers stop noticing they're talking to AI.

Where it still fails

Highly emotional calls, complex multi-party negotiations, dialects far from training data, and calls that require nuanced judgment. We scope every deployment to where the AI is reliably good — and route the rest to humans.

Checklist

  • Scope deployments to routine, repeatable calls
  • Test with real users, not internal demos
  • Plan handoffs explicitly
  • Re-evaluate models quarterly — the field moves
