Third Workshop on Child, Computer and Interaction (WOCCI 2012)
Portland, OR, USA
This article presents an approach to the automatic assessment
of the oral reading fluency (ORF) of children in Spain who
are learning to read English. We compared different acoustic
modeling configurations and adaptation methods to determine
the most accurate means of estimating reliable children's oral
reading fluency scores using the standard metric of words correct
per minute (WCPM). We addressed the problem of identifying
word errors by extracting a series of features in order to
learn how the human experts are actually annotating individual
Experimental results show that the difference between WCPM scores produced by the proposed system and two human judges on the same text is smaller than the average difference between the scores produced by the two judges. In addition, the system scored individual words in texts as correctly or incorrectly read with an accuracy similar to that of human annotators.
