Description

Nazila Ameli and six co-authors train a deep learning system to flag mispronounced sounds in children's speech recordings. Speech sound disorders are common and can affect school and social outcomes, but expert listening assessment is slow and varies between raters. Automated screening could triage children where specialists are scarce.

One hundred participants aged six to eighteen recorded eighteen hundred words under a protocol focused on fricative sounds. Two expert speech-language pathologists labeled each recording, with a third settling disagreements, and reliability was measured carefully. A pretrained transformer speech model was fine-tuned on the cleaned audio for present-or-absent classification. Imbalance tricks included augmentation, weighted sampling, and focal loss. Performance was judged on a held-out test set.
