The Singing and Voice Science Laboratory

Directed by Molly Erickson, Ph.D.

The Singing and Voice Science Laboratory located in South Stadium Hall and is designed to conduct research both at the Master's and Ph.D. levels in the areas of music perception and voice science. The lab is equipped with a large sound booth for recording speakers and professional singers. It also boasts equipment and software capable of performing a variety of research tasks: a Glottal Enterprises system for air flow analysis, subglottal air pressure measurement, and 2-channel electroglottograph and inverse filtering and a variety of programs used to produce real-time spectrograms and Fast Fourier analyses.  
The laboratory has available several methods of signal synthesis: signal generation hardware and software from Tucker-Davis Technologies, a Klatt synthesizer, and a singing voice synthesizer built using Aladdin. Perceptual experiments are designed and conducted using a variety of software and hardware combinations.  
The laboratory makes use of departmental equipment designed to visualize vocal fold vibration including: digital KayPentax stroboscopy, high speed video, and videokymography. This equipment is used to visualize the vocal folds for both voice physiology research and clinical diagnostics. 

  • Acoustics and perception of singing

  • High speed video and videokymography

  • Speaker identification in cochlear implant users

  • Music processing in cochlear implant users

The Singing and Voice Science Research Laboratory is seeking experienced singing voice professionals for a study in singing perception.  Please e-mail for more information.

Volunteering in the Singing and Voice Science Research Laboratory is a great way to learn about research and clinical issues in the areas of music and singing.  Volunteers may aid in the areas of  stimulus development, data collection, and data analysis.  If you are interested in volunteering in the Singing and Voice Science Research Laboratory, please e-mail Dr. Erickson at
