100 Years of Voice and Speech
The field of voice and speech science has developed over the past century into a rich, interdisciplinary domain—bridging medicine, acoustics, linguistics, vocal performance, and biomechanics. From early anatomical studies to the emergence of high-speed imaging and computational modeling, researchers have sought to understand the mechanics, resilience, and expressive power of the human voice.
At the National Center for Voice and Speech (NCVS), we honor the legacy of those pioneers by preserving and sharing the stories, research, and breakthroughs that shaped this evolving field. The past 100 years have brought remarkable advancements—from the first laryngeal visualization techniques to modern voice therapy practices and voice synthesis technologies.
Today, NCVS serves as a living archive—a curated history of the people, ideas, and innovations that brought voice and speech science to where it is today. As the field continues to grow, we remain committed to amplifying its impact and ensuring its history informs its future.
Whether you’re a researcher, clinician, performer, or student, we invite you to explore the voices behind the science—and the science behind the voice.
Latest Books
Sing and Shout for Health
Sing and Shout for Health explores the remarkable impact of vocalization on human physiology, health, and well-being. Edited by renowned physicist Ingo R. Titze and vocologist Elizabeth C. Johnson, this groundbreaking book delves into scientific discoveries that reveal how singing, shouting, and other forms of vocalization influence the body at molecular, physiological, and neurological levels.
Voice is Free After SOVT
Voice is FREE after SOVT distinguishes itself as the first book dedicated to Semi-Occluded Vocal Tract methods and is inclusive with scientific explanation and application for singer, teacher and therapist alike. It incorporates a large bibliography of the evolution of these methods and an enormous amount of current peer reviewed literature in the area of voice.
Vocology
The Science and Practice of Voice Habilitation is the first major textbook written in the field of Vocology. It addresses the fundamental postulates and exercises underlying voice habilitation, the art and science of taking a voice beyond normal conversational skills. It introduces voice measurement and assessment (vocometrics), motor learning principles, the carrier-modulation hierarchy, and the union if breathing, valving, and voicing.

Recent Insights into Vocal Injury in Singers
Vocal injury in singers can trigger a great deal of fear and uncertainty. A sudden change in the voice during or after a performance may raise the specter of a career-ending injury in the mind of the singer, and a voice that does not recover in due time can directly impact a singer’s livelihood. Much of the misgivings surrounding vocal injuries are attributable to a lack of accurate medical information on the nature of vocal injuries, how they are treated, and real-world outcomes. Several papers in the recent scientific voice literature shed light on these issues and may alleviate the singer’s concerns.
Air Pressures That Are Critical in Vocal Fold Vibration
As singers and speakers, we care about efficient ways to use our voices. Questions regarding the effective use of air pressure and airflow arise. For example: To get louder, is it just about pushing harder with more lung pressure? Or, are there other ways to tune up the system to get more bang for the buck? Let’s get some insights into various pressures in our airways.
Machine Learning for Voice and Speech Science
Machine Learning is a subfield of artificial intelligence that enables computers to learn patterns or models from data and improve with experience without programming explicitly
