Public invited to UI Presidential Lecture on the human
voice Feb. 18
IOWA CITY, Iowa -- A fascination with the human voice
led Ingo Titze, Ph.D., University of Iowa Foundation Distinguished Professor
in the department of speech pathology and audiology and the School of Music,
to apply his scientific expertise as a physicist and engineer to research
issues related to the voice and vocal music.
Titze has studied such topics as biomechanics of human
tissues, voice disorders, professional voice production, musical acoustics
and the computer simulation of voice. He will share his enthusiasm and knowledge
-- and even a few songs -- when he presents the 2001 Presidential Lecture,
"Fascinations with the Human Voice," at 3:30 p.m. Sunday, Feb. 18 in the Levitt
Center for University Advancement.
The free lecture, which opens with two Mozart tenor-baritone
duets sung by Titze and John Muriello, assistant professor of voice in the
UI School of Music, will focus on five "fascinations."
"The first fascination I'll discuss is how it's possible
that such great sounds can come from basically a fairly lousy instrument,"
said Titze, who directs the National Center for Voice and Speech, a consortium
of investigators at the UI, the University of Wisconsin-Madison, the Denver
Center for the Performing Arts, and the University of Utah.
"If you look at the way the human vocal folds and
vocal tract are structured, compared to what we see in high-quality man-made
instruments that are constructed to make beautiful sounds, you'd think this
critter has no chance," he said. "Yet with a wonderful brain attached, we're
able to compensate for and make use of these irregularities and not-so-nice
properties of the tissues."
Titze will use visuals to help illustrate dimensional
differences between certain musical instruments and the voice.
The other four fascinations he will describe include:
what our voice tells others about us, from mood to health to social upbringing;
how well the voice and the ear work together acoustically; how powerful the
voice can be in terms of revealing emotions or protecting ourselves or others
from danger; and how easy it is to use a computer to simulate the vocal bravado
we hear in voices like
opera great Luciano Pavarotti, yet how difficult it is
to use a computer to reproduce simple ordinary speech.
Pavarobotti, the singing robot designed by Titze that
uses sophisticated computer simulation of the human voice, will not be "performing"
at the lecture. However, Titze will provide related sound recordings and video.
Titze hopes people will come away from his lecture
not only with an increased understanding of the human voice but also with
a greater awareness of the need to be more health conscious about preserving
"We hear so much about protecting our ears and hearing,
but so little has been said about protecting our voice-production organs,"
Titze said. He will also tell people about outreach programs at the National
Center for Voice and Speech.
Titze has published more than 250 articles in scientific
and educational journals. He also is the author of the book "Principles of
Voice Production," and coedited two books in a series entitled "Vocal Fold
Physiology." He is currently completing two additional books ,"Vocology" and
"The Myoelastic-Aerodynamic Theory of Phonation." He is an associate editor
of the Journal of Singing and has written a bi-monthly column in this journal
for 20 years.
Titze is a recipient of the William and Harriott Gould
Award for laryngeal physiology, the Jacob Javits Neuroscience Investigation
Award, the Claude Pepper Award, the Quintana Award of the Voice Foundation,
and the American Laryngological Award. He is a fellow of the Acoustical Society
of America, the American Speech Language and Hearing Association, and the
American Laryngological Association.
He and his work have been featured in several well-known
television programs, including "Innovation," "Quantum," and "Beyond 2000."
In addition to his scientific endeavors, Titze continues
to be active as a singer, giving several recitals a year in the United States
and Europe, at times joined by Pavarobotti.
