Documentation

  • Digital audio or audio-video recordings should be performed, with a microphone of high quality.
  • The microphone should be placed so that the person's speech is captured optimally, and other noise is avoided.
  • The background of the video recording should be "clean" and with good enough light.
  • In research, one person should operate the camera with focus on the person's head and shoulders. Pictures should be displayed from the front so that the person does not look down. A clear image of the face should be recorded with no visual distraction (Lohmander et al., 2009).
