Questions to resolve with Deepgram

- Keep prerecorded requests separate from live streams when comparing protocol, final events and billing.
- For a live agent, measure partial revisions and completed transcript quality as well as first-partial timing.
Sources and billing assumptions
Compare the same product, duration, region and features. Managed telephony is a separate PyAI line item and uses a one-minute pulse; other provider fees and billing units may differ. Check current terms for your configuration.
