Latency calculator

This estimator explains the main components of perceived delay. It is not a service-level guarantee and does not measure a live VaniAgent call.

Network round trip

120 ms

AI processing

450 ms

Audio buffering

160 ms

Estimated response delay 730 ms Generally conversational

Tune using evidence

Use a real call recording and runtime timing logs. Separate carrier/network delay, speech finalization, model processing, first audio generation, and playback buffering. Test the same agent, number, language, and destination before comparing providers.

Optimizing one component may reduce stability or naturalness. Measure interruption handling and audible output, not only server response timestamps.
