Replica.started_speaking/stopped_speaking

This is an event broadcasted by Tavus.

A replica.started_speaking/stopped_speaking event is broadcasted by Tavus at specific times: the replica.started_speaking is sent when the replica begins speaking, and a separate event for the replica.stopped_speaking is also sent as the replica stop speaking.

Replica.started/stopped_speaking events can be used to keep track of when the replica has started or stopped speaking.

The inference_id can be used to correlate other events with these replica.[started|stopped]_speaking events, so you can know what and when the replica said something.
