Work on spoken English grading gets accepted at ACL, AM-R&D going to Beijing!

Good news! Our work on using crowdsourcing and machine learning to grade spontaneous English has been accepted at ACL 2015.

  • Ours is the first semi-automated approach to grade spontaneous speech.
  • We propose a new general technique which sits between completely automated grading techniques and peer grading: We use crowd for doing the tough human intelligence task, derive features from it and use ML to build high quality models.
  • We think, this is the first time anyone used crowdsourcing to get accurate features that are then fed into ML to build great models. Correct us if we are wrong!

The technique helps scale spoken English testing, which means super scale spoken English training!

Great job Vinay and Nishant.

  1. Hey Kalyan,

    Thanks!

    Will look through the paper — excited to read it. Not sure, when in Boston, but soon. Will drop you a line in advance.

    Hope you are very well.

    Cheers
