I can forgive Watson for not understanding proper nouns, but not for confusing it's and its (given plenty of context).
The insertion of %HESITATION to denote pauses of speech is an unexpected delight.
A long time ago, as work-study, I transcribed several audio recordings of descendants of the first non-Native settlers of Santa Clara Valley. There were many ellipses in my transcriptions, and I wonder if future researchers will question if they represent hesitation, ums or uhs, or periods where the recording was unintelligible.
