Principles of voice production
TLDR
Basic Anatomy of the Larynx, Biomechanics of Laryngeal Tissue, and Fluctuations and Perturbations in Vocal Output. Expand
The physics of small-amplitude oscillation of the vocal folds.

  • Physics, Medicine
  • The Journal of the Acoustical Society of America
  • 1 April 1988
TLDR
It is shown that vocal tract inertance reduces the oscillation threshold pressure, whereas vocal tract resistance increases it, and the treatment is harmonized with former treatments based on two-mass models and collapsible tubes. Expand
Voice simulation with a body-cover model of the vocal folds.
  • B. Story, I. Titze
  • Physics, Medicine
  • The Journal of the Acoustical Society of America
  • 1 February 1995
TLDR
Simulations show reasonable similarity to observed vocal-fold motion, measured vertical phase difference, and mucosal wave velocity, as well as experimentally obtained intraglottal pressure. Expand
Nonlinear source-filter coupling in phonation: theory.
  • I. Titze
  • Physics, Medicine
  • The Journal of the Acoustical Society of America
  • 9 May 2008
TLDR
A theory of interaction between the source of sound in phonation and the vocal tract filter is developed and positive reinforcement of the harmonics by supraglottal inertive reactance (and to a lesser degree by subglottal compliant reactance) is shown to be influenced by interaction. Expand
Vocal tract area functions from magnetic resonance imaging.
TLDR
Comparisons of formant locations extracted from the natural (recorded) speech of theImaged subject and from simulations using the newly acquired area functions show reasonable similarity but suggest that the imaged vocal tract shapes may be somewhat centralized. Expand
Voice training and therapy with a semi-occluded vocal tract: rationale and scientific underpinnings.
  • I. Titze
  • Medicine
  • Journal of speech, language, and hearing research…
  • 1 April 2006
TLDR
Investigating the underlying physical principles behind the training and therapy approaches that use semi-occluded vocal tract shapes found that therapy approaches are designed to match the glottal impedance to the input impedance of the vocal tract. Expand
Physiologic and acoustic differences between male and female voices.
  • I. Titze
  • Mathematics, Medicine
  • The Journal of the Acoustical Society of America
  • 1 April 1989
TLDR
Comparison is drawn between male and female larynges on the basis of overall size, vocal fold membranous length, elastic properties of tissue, and prephonatory glottal shape and the simulated vocal fold contact area is used to infer male-female differences in the shape of the glottis. Expand
Populations in the U.S. workforce who rely on voice as a primary tool of trade: a preliminary report.
The United States Bureau of Labor Statistics and other sources were consulted about the percentages of the working population that we identified as professional voice users. The largest percentageExpand
On the relation between subglottal pressure and fundamental frequency in phonation.
  • I. Titze
  • Physics, Medicine
  • The Journal of the Acoustical Society of America
  • 1 February 1989
TLDR
It is shown that the typical 2-6 Hz/cm H2O rise in fundamental frequency with subglottal pressure observed in human and canine larynges is a direct and predictable consequence of this amplitude-frequency dependence. Expand
