Speech Physiology Lab

Laboratory Phone Number: (765) 494-6488
Location: Heavilon Hall G30
The Speech Physiology Laboratory is located on the first floor of Heavilon Hall. The primary focus of research within the laboratory is the treatment of speech and cognitive changes which occur with motor speech disorders, particularly Parkinson's disease, and which occur as a part of typical aging. Research interests in the laboratory are broad, covering a wide range of topics, all related to quality of life for older adults and individuals with Parkinson's disease. The laboratory staff members collaborate with several other laboratories at Purdue University, faculty at the University at Buffalo, and Neurologists at the Indiana University Medical Center.
The laboratory is equipped for making simultaneous recordings from the speech subsystems (respiratory, laryngeal, and articulatory) in order to examine how the components work together for speech production. A respitrace system is available for the collection of respiratory information. Circumferentially-vented pneumotachograph masks and pressure transducer (Glottal Enterprises) are used for the collection of oral airflow and air pressure data.
High quality microphones allow for the transduction of acoustic signals which are examined spectrally to assess the articulation. The lab is equipped with eight computer workstations for analysis of data.
