| nr_speech_segments | How many different speakers were identified by diarization within the duration of the speech (often but not always false negatives)                                                                                                                                                                                                                         |
| start_segment_same | Is the `start_segment` of this speech a duplicate of some other speech's estimated `start_segment`? About ~150 speeches have the same identified start time. Generally either one of the two is correct, or there was a failure case of diarization that created too broad a speech duration that covered parts of two speeches.<br>                 |
