When to use this
- Agent build UIs: populate the transcriber selector when creating or editing an agent.
- Latency tuning: choose between streaming transcribers (lowest first-word latency) and batch transcribers (best accuracy on noisy audio).
- Language coverage checks: confirm the transcriber supports the language an agent is configured for.
- Cost optimization: switch high-volume use cases to lower-cost engines when accuracy budget allows.
