Monthly latency report
Voice stack latency report
Each month I measure turn latency across the major hosted voice stacks under one identical prompt set, then publish the results with the raw CSV. This page is the index.
How it is measured
This is the fixed method every report follows. The rows below describe how a run is set up, not any measured result.
- Primary metric
- Turn latency at p50 and p95.
- Measured from
- The moment the user stops speaking to the first audio byte back.
- Also captured
- Barge-in response time and call-setup time.
- Stacks covered
- The major hosted voice stacks.
- Sample size
- 30 calls per stack (N = 30).
- Prompt set
- One identical prompt set, reused across every stack.
- Raw data
- A raw CSV published alongside each report.
- Cadence
- Published the same calendar day each month.
No measurements are published yet. Nothing here is estimated or modeled.
