<pre>
Output only. A distinct integer value is assigned for every speaker within
the audio. This field specifies which one of those speakers was detected to
have spoken this word. Value ranges from 1 up to diarization_speaker_count,
and is only set if speaker diarization is enabled.
</pre>

<code>int32 speaker_tag = 5 [(.google.api.field_behavior) = OUTPUT_ONLY];</code>

@return The speakerTag.
