<pre>
Output only. A label value assigned for every unique speaker within the
audio. This field specifies which speaker was detected to have spoken this
word. For some models, like medical_conversation this can be actual speaker
role, for example "patient" or "provider", but generally this would be a
number identifying a speaker. This field is only set if
enable_speaker_diarization = 'true' and only for the top alternative.

<code>string speaker_label = 6 [(.google.api.field_behavior) = OUTPUT_ONLY];</code>

@return The bytes for speakerLabel.
