description: Estimate how network, AI processing, and audio buffering affect perceived response time.

import LatencyCalculator from '../../../components/LatencyCalculator.astro';

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

## 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.
