Dr. Jennifer and Emanuel Bodner Developmental Stuttering Laboratory

The Developmental Stuttering Laboratory (DSL) was established in 2006 by Courtney T. Byrd, PhD, CCC-SLP in the Department of Communications Sciences and Disorders at The University of Texas at Austin. The DSL was developed to pursue two main goals:

Goal 1 - ACSIR: To develop and provide evidence-based treatment to children and adults who stutter.

Goal 2 - Etiology: To investigate the nature of stuttering from onset through development.

In addition to conducting treatment efficacy research and research related to the causal contributors/maintainers of stuttering, the DSL is also committed to training undergraduate, masters, and doctoral students who plan to specialize in stuttering and to disseminating information about stuttering through conducting continuing education workshops for practicing speech-language pathologists, facilitating bi-annual public forums for persons who stutter and their families, holding the National Stuttering Association monthly local chapter meetings, presenting research at national and international conferences, and publishing data in refereed journals.

Description

The DSL is outfitted with 1 administrative computer, 2 testing computers, and 2 analysis computers. The testing workstations in the lab are configured to allow for DVD recording of test subjects for later analysis (see Goal 2). The recordings feature studio quality audio of the test subject, a close-up video image of the test subject's face and a small video inset window showing the testing workstation's display. Additionally, the testing workstations utilize serial response boxes which allow for timing subject response using tactile button presses and spoken feedback. One of the testing workstations also features high-fidelity direct-to-disk recording and analysis tools for analyzing specific aspects of the human speech process.

The analysis workstations in the lab are configured to allow easy viewing, transcription, and coding of previously recorded DVDs. The workstations feature high-fidelity monitor speakers, headphones, and multiple monitors to allow for efficient workflows. In order to guarantee the highest fidelity recordings during lab tests, the lab has been fitted with sound proof insulation and the lab utilizes high-quality condensor microphones, studio-grade microphone pre-amps, and studio-grade wiring and accessory electronics. Software and data co-processors specific to the functions of the lab include E-Prime, the research version of SALT V9, and CSL. Finally, the location of the lab within the UTSHC facilitates Dr. Byrd’s ACSIR program (see Goal 1) by allowing direct access to the 12 available therapy rooms that come equipped with two-way mirrors and audio and video recording devices.
