Improving automated scoring of prosody in oral reading fluency using deep learning algorithm
Abstract
Automated assessing prosody of oral reading fluency presents challenges due to the inherent difficulty of quantifying prosody. This study proposed and evaluated an approach focusing on specific prosodic features using a deep-learning neural network. The current work focuses on cross-domain performance, researching how generalizable the prosody scoring is across students and text passages. The results demonstrated that the model with selected prosodic features had better cross-domain performance with an accuracy of 62.5% compared to 57% from the previous research. Our findings also indicate that students’ reading patterns influence cross-domain performance more than specific text passage patterns. In other words, letting the student read at least one passage is more important than having others read all passage texts. The specific prosodic features had a high generalization to capture the typical prosody characteristics for achieving a satisfactorily high accuracy and classification agreement rate. This result provides valuable information for developing future automated scoring algorithms of prosody. This study is an essential demonstration of estimating the prosody score using fewer selected features, which would be more efficient and interpretable.
