# Latency

> Where latency comes from and how to reduce it

Voice AI latency is the sum of transcription, LLM generation, and speech synthesis
time. Agentic OS streams every stage to minimize perceived delay.

## Reducing latency

* Use a streaming-capable LLM configuration
* Choose a low-latency transcriber model
* Tune the synthesizer to start playback as early as possible
* Keep response length short for faster generation
* Host your agent's LLM provider in a region close to your telephony provider

<Callout type="info">
  Typical end-to-end latency on Agentic OS is 600–900ms for a well-tuned agent.
