About Lessac-Madsen Resonant Voice Therapy (LMRVT)

Our center is the ONLY speech therapy center who has invited Dr. Verdollini Abbott to conduct voice training workshop. She was the founder of Lessac-Madsen Resonant Voice Therapy (LMRVT). In year 2010, our center has organized LMRVT Asian Tour with other speech therapy associations in Singapore, India and Taiwan. Our center's speech therapists are ALL certified provider of Lessac-Madsen Resonant Voice Therapy (LMRVT).
Lessac-Madsen Resonant Voice Therapy (LMRVT) was widely used in the United States and other countries. The efficacy of resonant voice therapy to improve voice quality was highly evidence-based. Initial and recent studies showed that resonant voice training was useful in helping to improve the signs and symptoms associated with vocal fold nodules and polyps (Verdolini-Marston, Burk, Lessac, Glaze, & Caldwell, 1995).
Dr. Katherine Verdollini Abbott, Professor in the Department of Communication Science and Disorders, has developed a systematic approach of Resonant Voice Therapy called Lessac-Madsen Resonant Voice Therapy (LMRVT). All patients who receive voice training have goals of producing a strong and clear voice over a distance or in background noise as well as to prevent future injury to vocal folds.

The program focuses on:
  • Individualized voice care program by therapist
  • Introduction of resonant voice and explore how it can SOUNDS good and FEELS good
  • Variable practice (i.e. practice on resonant voice on words, phrases, sentences)
