EndOfUtterance:
summary: |
Indicates the end of an utterance, triggered by a configurable period of non-speech.
The message is sent when no speech has been detected for a short period of time, configurable by the `end_of_utterance_silence_trigger` parameter in `conversation_config` (see [End Of Utterance](https://docs.speechmatics.com/speech-to-text/realtime/end-of-turn#end-of-utterance-configuration)).

Like punctuation, an `EndOfUtterance` has zero duration.
