Letter sound and letter name recognition for automated literacy assessment of young children
Abstract
Evaluations of letter naming and letter sounding are commonly used to measure a young child's growing reading ability, since performance in them is well‐correlated with future reading development. Assessing a child's oral reading skills requires teachers, as well as technologies that attempt to automate such assessment, to form an item‐level accept/reject decision based on speech cues and prior knowledge of the child's literacy level and linguistic background. With data collected from 171 K‐2 children, both learners and native speakers of American English, we designed and evaluated an automated letter naming assessment method using a simple word‐loop HMM decoding for the word‐level letter names. The automated accept/reject evaluation performance, 81.9%, approached the agreement of human raters, 83.2% (0.62 kappa). However, the task where children must produce the sound that the letter …
