In accordance with TalkBank rules, any use of data from this corpus must be accompanied by at least one of the above references.
This corpus includes data from the SLI children of the GRAMAT research, carried out by Gerard Bol and Folkert Kuiken between 1984 and 1988.
The GRAMAT research aimed at two questions: 1) Is it possible to discern patterns in the morphosyntax of three groups of language-disordered children — children with SLI, with Down syndrome, and with hearing impairment, and 2) Can these patterns be related to the clinical characteristics of the children? Analysis of samples of spontaneous speech produced an affirmative answer to the first question. The answer to the second question is that the different clinical characteristics of the children did not lead so much to different kinds of language disorders as to differences in the degree of being language disordered. The three groups of children showed more commonalities than differences in producing morphosyntax.
The 20 Dutch hearing impaired children (11 male and 9 female) in this research ranged in age from 3;11.14 to 9;00.15. They all suffered from sensorineural or mixed hearing loss. Their hearing impairment had been diagnosed before they were 1;6 years of age. Their hearing loss differed from 40 to 85 dB pure tone average on the better ear. The cildren were of normal intelligence. The names of the children in the corpus are pseudonyms. Participants are identified by first names and with a five-digit code, indicating the age of the child in years, months, and days. Further information about the children is given below.
The speech of the 20 hearing impaired children was audiotaped at their school, while they were playing with their speech therapist in a free-play situation. One of the two investigators was present in the room of the speech therapist. From time to time the investigator participated in the conversation. From each child 100 analyzable utterances were transcribed by the investigator that had been present at the recording.
