Is It Self-Awareness or Is It Sensory Feedback? Difficulties in Self-Perception of One’s Own Voice in People with Parkinson’s Disease
Many people with Parkinson’s disease don’t notice their own voice changes. Francisco Contreras-Ruston on why hypophonia is a sensory-feedback problem, not just a motor one, and what it means for assessment and treatment.
Why Vocal Fry is not Recommended for Speech
Why is vocal fry problematic in speech? Ingo Titze, Marco Guzman, and Miriam van Mersbergen use communication theory to explain how vocal fry increases cognitive load on listeners and reduces intelligibility.
Singing for Cardiovascular Health
Regular exercise protects the heart, yet most U.S. adults fall short of activity guidelines. Could singing offer an accessible way to support cardiovascular health?
Can you scream like a Piha bird at a ballgame?
The Screaming Piha produces one of the loudest calls in the animal kingdom. What can this small South American bird teach us about the limits of vocal loudness — and could a human ever match it?
Toward Conditioning-Based Approaches for Vocal Fatigue in Professional Voice Users
Professional voice users report that vocal fatigue is the number one issue they face. Can physical conditioning help mitigate the issue?
Primary Muscle Tension Dysphonia: The Term has Got to Go
Is Muscle Tension Dysphonia the right diagnosis? Marco Guzman and Kittie Verdolini challenge the term and what it reveals about voice disorder treatment.
A Review and Summary of Karin Titze Cox and Ingo R. Titze’s Most Recent Publication Voice Is FREE after SOVT: Semi-Occluded Vocal Tract Principles, Methods, and Training
A concise review of “Voice Is FREE after SOVT,” exploring semi-occluded vocal tract principles, methods, and training for healthier, efficient voice use.
My Path Through the Intersection Between Voice and Psychology
What happens when voice science meets psychology? In this reflective piece, Dr. van Mersbergen explores how the voice may serve as a powerful yet underutilized window into the mind.
The Power of the Question
Scientific progress begins long before data are collected. Dr. Ingo R. Titze examines the overlooked power of asking the right question, arguing that profound inquiry—not merely statistical strength—drives meaningful discovery and intellectual growth.
Voice and Artificial Intelligence: The Role of Vocologists
Artificial intelligence is reshaping voice science, from clinical assessment and vocal biomarkers to forensic analysis and human–AI interaction. This article examines the critical role of vocologists in guiding ethical development, ensuring data quality, and preserving the authenticity and diversity of the human voice as AI technologies accelerate.
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.
