Replica Started/Stopped Speaking Event
This is an event broadcasted by Tavus.
A replica.started_speaking/stopped_speaking event is broadcasted by Tavus at specific times:
conversation.replica.started_speaking means the replica has just started speaking.
conversation.replica.stopped_speaking means the replica has just stopped speaking.
When the replica.stopped_speaking event is sent, a duration field will be included in the event’s properties object, indicating how long the replica was speaking for in seconds. This value may also be null.
These events are intended to act as triggers for actions within your application. For instance, you may want to start a video or show a slide at times related to when the replica started or stopped speaking.
The inference_id can be used to correlate other events and tie things like conversation.utterance or tool_call
together.

"conversation"
This event occurs when the replica either starts actually speaking audio, or stops actually speaking audio.
