Project Description

This corpus contains 27 files of data collected by M. J. Demetras and John Umbreit between 1985 and 1987 from their son Trevor. Nine sets of four 20-minute conversations between Trevor and his father were recorded over a period of 35 months for a total of 28 sessions. All but one session were transcribed and included as part of this corpus. The context was free play and the participants used a somewhat standard set of toys through the duration of the recordings. Trevor was fairly intelligible and verbal at this stage in development. He also experienced two episodes of disfluency during this period, which was partially captured in the data. Trevor was born on June 3, 1983.
