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
Typical end-to-end latency on Agentic OS is 600–900ms for a well-tuned agent.
