SoapBox Fluency API uses automatic speech recognition (ASR) to return data points that enable educators to assess a child's oral reading fluency (ORF). Prosody is a key component of ORF assessment together with accuracy and speed, but manual assessment of prosody is largely subjective. A quantitative prosody score would benefit fair assessment. In this show and tell paper and accompanying video, we describe the new prosody feature of the API and demonstrate how the outputs can be used to assess expressiveness in ORF.
