Your voice agent probably isn't slow because of the LLM.
A developer debunks the common belief that LLM latency is the primary cause of slow voice agents, explaining that delays often stem from earlier stages like audio capture, VAD, and STT. They recommend logging specific latency metrics and testing various STT/TTS providers and orchestration frameworks to diagnose issues.

Your voice agent can't catch its own over-promises. That's a structural problem, not a tuning one.
The article identifies a structural flaw in voice agents where they cannot detect when they over-promise across multiple conversation turns, and describes building a deterministic checker that flags contradictions without relying on LLM evaluation.
