In the Speech Production Laboratory, we aim to discover the mechanisms underlying both normal and disordered speech sound production, and to develop technologies that are capable of putting our discoveries to good use. The laboratory features a unique combination of state-of-the-art equipment for speech data collection, including a 3D/4D ultrasound machine, a whole-body plethysmograph, oral and nasal airflow masks, accelerometers, microphones, headphones, and a "wet lab" station for making and digitizing plaster casts of the palate and teeth. We have excellent computing resources with both Windows and Linux operating systems, as well as software licenses for MATLAB and LabView, in addition to Python and C++ software development capabilities. Three questions which are currently being explored in detail are: 1) How does 3D tongue and palate shape vary across individuals? 2) What effect does lung health or disease have on speech acoustics? 3) How do the acoustic properties of the vocal tract and lungs affect vocal fold vibration?
