I want to try Otter live captions application on my iPhone for a public meeting – town Board of Selectmen. It 'listens' to the room and types the words. It is similar to CaptionCall or Captel telephones, but it is listening to the room. Does anyone have experience with Otter? If it works adequately (90% accuracy?) I would need to project my iPhone screen onto a larger screen for hard-of-hearing people to read. Any ideas? Thank you in advance.
