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[7] 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.
Titze was a consultant to the Department of Linguistics/Speech Analysis at Bell Laboratories, Murray Hill, a visiting Lecturer at the Department of Hearing/Speech Science at the University of Maryland, and an associate professor for the Department of Speech Pathology and Audiology for the University of Iowa from 1979–1995.
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,
Between the years of 1979–1981, Titze developed a new course entitled Principles of Voice Production, which was taught jointly in the School of Music. During the 1980s he developed various university courses that included acoustics, biomechanics of speech, experimental phonetics, digital signal processing, voice therapy and vocal pedagogy, all of which culminated in him coining the phrase 'vocology', which he then proposed as a discipline parallel to audiology.
Titze has been awarded multiple grants during his career[8] from the National Institutes of Health, to study voice health and voice disorders. His research on the voice is prolific,[9] with over 160 research articles listed at the NIH, alone.
