Wang et al. (2018) [pdf]

  • Automated scoring model for evaluating English spoken responses
  • SpeechRater gave a significantly lower score than human raters for German
  • SpeechRater scored in favor of Chinese group, with H1-rater scores higher than mean

  • a model (the SpeechRater) automatically scoring open-ended spoken responses for speakers with documented or suspected speech impairments
  • SpeechRater was less accurate for test takers who were deferred for signs of speech impairment (ρ2 = .57) than test takers who were given accommodations for documented disabilities (ρ2 = .73)
