Titze received a B.S. in Electrical Engineering from the University of Utah, and then an M.S.E.E. in Electrical Engineering, with a minor in Physics from the University of Utah. He graduated with a Ph.D. in physics from Brigham Young University in 1972. In 1976 he went to Gallaudet University, where he received his first of many grants from the National Institutes of Health.
Prior to his conjoint positions at the Universities of Utah and Iowa (for which he began in 2009 and 1990, respectively) he was the Chief Scientist and Executive Director for the National Center for Voice and Speech from 1994–2009, which was then housed at the Denver Center for the Performing Arts.
From 1983–1994 he served as the Director of Research for the Recording and Research Center, also housed at the Denver Center for the Performing Arts, and from 1989–1994 he was adjunct professor in the Westminster Choir College at Princeton, New Jersey.
Before accepting a position to work as a research engineer at the Boeing Company of Seattle from 1968–1969, he worked at the National Reactor Test Station (1965–1966) and as a research engineer at North American Aviation in Tulsa, Oklahoma,
Titze has been awarded multiple grants during his career from the National Institutes of Health, to study voice health and voice disorders. His research on the voice is prolific, with over 160 research articles listed at the NIH, alone.
