Towards an Automated Screening Tool for Developmental Speech and Language Impairments

摘要

Approximately 60% of children with speech and language impairments do not receive the intervention they need because their impairment was missed by parents and professionals who lack specialized training. Diagnoses of these disorders require a time-intensive battery of assessments, and these are often only administered after parents, doctors, or teachers show concern. An automated test could enable more widespread screening for speech and language impairments. To build classification models to distinguish children with speech or language impairments from typically developing children, we use acoustic features describing speech and pause events in story retell tasks. We developed and evaluated our method using two datasets. The smaller dataset contains many children with severe speech or language impairments and few typically developing children. The larger dataset contains primarily typically developing children. In three out of five classification tasks, even after accounting for age, gender, and dataset differences, our models achieve good discrimination performance (AUC > 0.70).
