Project Description

Data for PERCEPT-GFTA were drawn from 17 studies that are published or under review and 4 studies that have not yet been submitted for peer review. The majority of talkers in this corpus were children and adolescents aged 6-17; adult talkers are included in one sub-corpus. Participants were required to speak American English as a dominant or equally dominant language. They were recruited from sites in New York and New Jersey, USA. Information about the number of participants in each study and their range of ages can be found in this table. Individual-level age and sex information is provided as part of the corpus records.

The corpus is divided into four sub-corpora reflecting different talker categories. These categories include (1) children with a history of speech sound disorder (SSD) in the preschool years, (2) children and adolescents recruited for suspected Childhood Apraxia of Speech (CAS), (3) children, adolescents, and young adults recruited for suspected SSD affecting rhotic production, (4) children and adults characterized by typical speech production.

The recordings presented here are isolated words, as well as some multi-word phrases, elicited in the context of the Goldman-Fristoe Test of Articulation (GFTA). Table 1 contains information about the edition of the test used (GFTA-2 or GFTA-3). Most of the component studies were conducted in the lab setting, with audio recorded using a participant-worn headset (e.g., AKG C520) or lavalier mic (e.g., Sennheiser MKE 2). Each record in the corpus contains an orthographic and IPA target record for the utterance in question. IPA transcription of participants’ actual productions has not been obtained to date.

For additional detail, see publication (1) listed below, or any of the publications linked to sub-corpora, as indicated in Table 1.

The files that make up this corpus are formatted for use with Phon software. An additional version of the same corpus, formatted for ease of use in training of Automated Speech Recognition (ASR) systems, can be found in the Derived Corpora section at https://phonbank.talkbank.org/derived/.
