Project Description

The children in this corpus were preschoolers ages 4-5 years. All were monolingual speakers of American English and all resided in upstate New York. All had speech sound disorders (SSD) as identified by local speech-language clinicians and verified by the Goldman Fristoe Test of Articulation-2. Receptive language was broadly within normal limits based on the Peabody Picture Vocabulary Test-4 (PPVT-4) and the Sentence Structure and Concepts & Following Directions subtests of the Clinical Evaluation of Language Fundamentals: Preschool-2 (CELF-P2). Additionally, all children participated in phonological awareness assessments.

The recordings presented here include a 125-item picture naming task designed to assess all English sounds at least twice in initial, medial, and final positions of words. Recordings were collected with a digital voice recorder and were sampled at 44 kHz. Data were collected either at the child’s home or at a university research lab setting. Phonetic transcriptions were completed by the same transcriptionist, a speech-language pathologist and doctoral candidate. Speech sound error types were classified as typical sound changes (e.g., phonological processes such as velar fronting, /s/ cluster reduction), atypical sound changes (e.g., deletion of onset singletons) and clinical distortions (e.g., lateralization of sibilants). Further details are provided in the publications listed above.
