Behind-the-mic at the EWVS 2025:

Dr. Med. Stefanie Rummel (EMCI) is a unique figure in the world of voice — a musical theatre performer, medical doctor, voice researcher, and international vocal coach who brings together science and stagecraft in service of the human voice.

  • Medical Doctor & Voice Expert: with a medical degree and deep expertise in vocal anatomy and health, Stefanie offers more than just technique — she brings clinical understanding to every coaching session. Her rare combination of medical knowledge and artistic experience makes her an invaluable guide for anyone who depends on their voice professionally.
  • Germany’s First Estill Mentor Course Instructor: Stefanie is one of the highest-certified Estill Voice Training specialists worldwide. She leads certification courses and masterclasses for singers, speakers, voice therapists, and educators — helping professionals master vocal techniques across genres and styles.
  • Cutting-Edge Voice Research: in collaboration with the Institute for Musicians’ Medicine at the University Clinic in Freiburg, Stefanie conducts research on vocal tract configurations, breath control, and acoustic properties using advanced 2D and 3D MRI imaging. Her scientific work is contributing to a deeper understanding of how the voice functions and how to train it efficiently and healthily.
  • Performer with Global Experience: Stefanie’s career as a musical theatre actress and musical cabaret singer has taken her across the globe — from stages in the US and UK to Australia. Whether performing in musicals, tours, festivals, or on cruise ships, her stage presence and vocal command have earned her international recognition.
  • Speaker on the International Stage: Stefanie regularly shares her insights at top global conferences, including PAS7+, PEVOC, ICVT, CAS Stimmwelten, ISIPAE, the Estill World Voice Symposium, Stuttgarter Stimmtage, and Voice Istanbul. Whether speaking to clinicians, coaches, or performers, she communicates complex voice science with clarity and passion.
  • Coaching Voices Around the World: At her Institut Rummel in Frankfurt, Germany — internationally and through online platforms — Dr. Rummel coaches a global clientele. Her students include professional singers on world tours, voice professionals in need of rehabilitation, and educators looking to deepen their practice.

At the symposium, on July 28, 2025, at 2:20 PM, Stefanie will present recent findings in a session entitled “2D MRI Vocal Tract Movements of Estill Voice Figures – Links Between Pedagogy and Science.” This research, conducted in collaboration with the Institute of Musicians’ Medicine at the University Clinic Freiburg (Germany), utilizes high-resolution 2D and 3D magnetic resonance imaging (MRI) to investigate the dynamic mechanisms of the vocal tract during singing and speaking. The presentation focuses on aspects such as tongue motion and spatial modifications of vocal tract structures associated with various Estill Voice Figures and Qualities, including Speech, Falsetto, Sob, Nasal & Oral Twang, Opera, and Belting.

By systematically correlating imaging data with pedagogical constructs from Estill Voice Training, the study provides interesting anatomical and physiological insights. These findings contribute to a more precise understanding of voice production and hold significant implications for evidence-based vocal pedagogy and performance training.
