The Science Underlying Semi-Occluded Vocal Tract Exercises (SOVT)
Tuesday 16th September 2025, 5:00 PM - 7:00 PM (London Time)
Semi-occluded vocal tract exercises have a long history. Humans and animals have discovered that aerodynamic and acoustic pressures above the larynx can position the vocal folds for better self-sustained oscillation.
Two variables are most important, (1) the steady pressure produced behind the semi-occlusion (usually the lips) and (2) the amount of acoustic inertance produced in the supraglottal airway.
In this course, Dr Ingo Titze and Karin Titze Cox will be exploring this topic in deph and it's relevance to vocal pedagogy.
This workshop will introduce the first book dedicated to Semi-Occluded Vocal Tract methods: Voice is FREE after SOVT. The information presented from the book is inclusive with scientific explanation and application for singer, teacher and therapist alike. The presentation will review the evolution of these methods and is based on a great deal of current peer reviewed literature in the area of voice.
Ingo and Karin will introduce visual examples, diagrams, tables and video links for reference. This should appeal to the scientist at heart searching for why their methods in vocal performance or as successful teachers, coaches or voice therapists work. Singers, teachers, coaches, ENTs, speech pathologists, research scientists and vocologists will be introduced to the comprehensive work, the history and current work being developed to help their clientele and patients even further. This can help trainers, performers and healers as it is heavily referenced with the development of voice science principles. These principles relate to all methods that use semi-occluded vocal tract exercises including the popular method of Straw Phonation popularized and developed extensively by both authors.
A framework for evaluation and training will be introduced to incorporate principles into their own style of teaching and training and translate difficult scientific principles to others.
Dr Ingo Titze
Dr Ingo Titze, educated as a physicist (Ph.D.) and engineer (M.S.E.E.), has applied his scientific knowledge to a lifelong love of clinical voice and vocal music. He has written over 500 publications and six books in voice production. He is currently Senior Scientist at the University of Utah Center for Vocology and Chairman of the Board of the National Center for Voice and Speech.

Introduction to Vocal Psychotherapy: Songs of the Self
Dr. Diane Austin

Unclenching the Jaw: Options from the Physio Lens
Walt Fritz
“Jaw tension” is one of many potential problems facing the singer, and can cause a direct negative impact on the performance in both direct and indirect ways. The underlying cause of jaw issues is attributed to numerous factors (technique, posture, strength, range of motion, etc.), making it often difficult to identify common denominators. Join Walt Fritz as he examines the evidence supporting stretching, strengthening, and manual therapy interventions to address jaw-related concerns in vocal performers, taking into account their unique needs.

Certificate in Foundations of Vocology with Adam Roberts
Adam Roberts
This 30-hour Vocology Cohort Intensive provides a comprehensive overview of basic vocal anatomy, physiology, and theories of voice production & perception, fundamentals of vocal health, pathology, evaluation, performance, and habilitation of the speaking and singing voice, and a survey of research, resources, and professional opportunities. Each week, advanced students contribute to cohort-centred learning with additional resources, discussion facilitation, and critical analysis. The course assessment will also be useful for those who wish to prepare for the PAVA recognised designation.
