AssemblyAI details voice-agent load testing before launch

AssemblyAI has published a technical guide on how to load test a voice agent before launch, arguing that demo performance on a single quiet-room call does not reflect production conditions. In the post, published on 2026-10-20, the company says teams should replay their hardest real calls through the full pipeline at projected peak concurrency and measure entity accuracy, P95 latency, rejected connections and cost per completed task. The article says load testing should cover the full voice stack — speech-to-text, the LLM, text-to-speech, tool calls and telephony — and should separate concurrency, throughput and session duration, because each fails differently.
