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.
NCVS Insights
On Whistle Register
Few sounds in the human voice are as mysterious—or as mesmerizing—as the whistle register. In this month’s NCVS Insights, Dr. Ingo Titze explores the science behind this elusive vocal phenomenon, unveiling a new hypothesis that could explain how singers reach frequencies well beyond the typical human range.
Ambulatory Voice Assessment: Challenges, Opportunities, and Future Directions
Continuous recording of voice on a daily basis has emerged as a new paradigm in voice assessment over the past decades. As an example, the ubiquity of smartphone technology has opened new possibilities to record, store, and process raw voice data, enabling researchers to investigate voice features in an ambulatory scenario with app-type software.
Human beatbox, the art of pushing back the limits of vocal possibilities
Human voice is undoubtedly the cheapest musical instrument in the world : everyone is born with it, and can train and develop it to suit his or her own aesthetic needs. Beyond its communicative functions, the human vocal instrument is capable of producing a wide variety of sounds, and imitating all kinds of other musical instruments.
Rethinking Voice Assessment for Practical Bedside Solutions
Advancements in voice assessment enhance diagnosis and clinical accuracy by complementing clinician expertise with objective data, yet many clinicians still rely primarily on subjective methods—not by choice, but because existing tools fail to integrate into workflows that provide practical clinical benefit. Nowhere is this challenge more evident than in hospital
Sex-related vocal attributes and specificities of the female voice
Sex-specific morphological differences in the three main subsystems of the vocal apparatus—namely the respiratory, oscillatory, and resonatory systems—affect both the production and perception of the voice. These differences should be taken into account by anyone concerned with vocal function and health and are therefore here explored.
The Vagus Nerve and Voice
Chapter three, “Vibratory Vagus Nerve Stimulation” from the recently released book, Sing and Shout for Health, Scientific Insights and Future Directions for Vocology explores the relationship between the vagus nerve, vocalization, vibratory stimulation, and the autonomic nervous system. The chapter provides a comprehensive overview of the vagus nerve, its anatomical relevance, and its role in the
