Speech Science Laboratory

Located in the David C. Phillips Building, the Speech Science Laboratory is directed by Dr. Harvey Gilbert. The laboratory is designed for students interested in the acoustic, aerodynamic, and physiologic investigation of normal and disordered speech and voice (children & adults). The laboratory facilities include and IAC single walled sound booth for subject testing, two CSL workstations, Laryngograph processor, Voice Range profiling, Rothenberg aerodynamic system, and a nasometer.

Recent/Current Student Projects:

Irena Vincent -- Smoking effects on acoustic, physiologic, and aerodynamic voice measures.
Hiroko Nakamura -- A comparison of speaking fundamental frequency measures between Japanese and American hearing impaired children.
Kirsten Lin -- Tone acquisition in Mandarin speaking children.
