Nasal Resistance Technique: Applications in Clinical and Performance Voice
Friday 11th July 2025, 5:00 PM - 7:00 PM (London Time)
This presentation introduces attendees to the Nasal Resistance (NR) Technique that combines semi-occluded vocal tract (SOVT) benefits with kinesthetic resonance awareness. The NR Technique promotes efficient glottal closure, resonance clarity, and smoother transitions across vocal registers. Its versatility makes it an essential tool for optimizing vocal efficiency in healthy, injured, and singing voices.
Dr. Nandhu Radhakrishnan will introduce the attendees to the theoretical background and clinical relevance of the NR technique using the nasal consonants /m/, /n/, and /ŋ/ (ng). Participants will actively engage in exercises involving nostril occlusion to experience first-hand the effects on airflow resistance, glottal closure, and sympathetic vibrations in the facial mask.
Dr. Kari Ragan will present studio applications of the NR Technique. Drawing from her extensive experience as a Singing Voice Specialist, she will demonstrate exercise patterns using glides and discuss their effectiveness across singing voice training. Attendees will learn how to apply the NR Technique to repertoire excerpts, fostering more efficient, kinaesthetically guided singing. Attendees will be encouraged to mirror exercises, adjust occlusion levels, and engage kinaesthetically through structured practice, ensuring a fully interactive experience.
Participants will leave with practical tools to integrate the NR Technique into teaching, therapy, and performance practices, enhancing sustainable, efficient voice production across diverse populations.

Water Resistance Therapy and Semioccluded Devices for Voice Training

Dr Marco Guzmán
Several voice devices to perform water resistance therapy (WRT) and some oscillatory positive expiratory pressure devices (OPEP) (e.g. Acapella Choice, Shaker Medic Plus, New Shaker) are now commonly used for both voice training and voice therapy. Are these devices truly good for voice training? Are these devices the treatment by themselves? and how much evidence currently supports the use of these devices?
