The University College London Archive of Stuttered Speech (UCLASS)

Abstract

Purpose This research note gives details of 2 releases of audio recordings available from speakers who stutter that can be accessed on the Web. Method Most of the recordings are from school-age children. These are available on the University College London Archive of Stuttered Speech (UCLASS) Web site, and information is provided about how to access the site. A description of the recordings and background information about the speakers who contributed recordings to UCLASS Releases One and Two are given. The sample types available in Release One are monologs. Release Two has monologs, readings, and conversations. Three optional software formats that can be used with the archive are described (although processing the archive is not restricted to these formats). Some perceptual assessment of the quality of each recording is given. An assessment of the strengths and limitations of the recording archive is presented. Finally, some past applications and future research possibilities using the recordings are discussed.
