-| start_segment      | Start time of the speech within the media file (filename can be found in `audio_file` variable). Obtained by running speaker diarization on top of fuzzy string matching in order to refine existing timestamps from fuzzy string matching (the values in `start_text_time`). This is generally the most accurate estimate of when the speech was given. |
