How I'm Beating a Raspy Voice & Pain in Talking

My problem started in my youth. I always sounded raspy and I could not carry on a conversation for very long without feeling pain in my throat. 

In 1990, I had speech therapy for the first time and experienced no improvement.

Hi Dr. Cooper,

I want to sincerely thank you for helping me recover from Spasmodic Dysphonia.

I first became aware of a problem with my voice about 8 or 9 years ago. Speaking was very difficult for me. Hardly anyone could understand me. Speaking on the telephone was an impossible chore.

I decided to consult with a physician who referred me to an eye, ear and throat specialist. The specialist could not find nay problems with my vocal cords. I was then referred to a neurologist who diagnosed Parkinson’s disease and prescribed L-dope. I refused to take the medication.

Botox vs. Direct Voice Rehabilitation

I am writing for several reasons. First, and foremost, is to thank you for your insightful assistance when I was in your care October 17-28, 1995. I accomplished much more than I expected and was most impressed, even after the first day, as to how much could be done with someone who knows what they're doing. I know for a fact that I have been misusing my voice for years and years (when I got home I suggested to my wife that I had likely been speaking from my throat at least the past 15 years or more; she quickly commented: "No, you were doing that when I met you 29 years ago.")

In 1985, I experienced a severe injury to my vocal cords. The physical pain was excruciating. The injury also caused a major impact to my promising career as a singer and drastically affected my ability to have a social life, for speaking felt like a tremendous effort. I had several odd symptoms; my neck muscles were in agonizing spasms.

19-Year Update

Dear Dr. Cooper,

As you know in the early 1980's I had a serious voice problem known as spastic dysphonia. I visited many medical doctors who diagnosed the problem as flu, allergy, paralysis, etc. The medical doctors at UCLA said it was an incurable permanent problem but they recommended surgery to help alleviate the symptoms.

Minnie Mouse is My Soul Mate

I had 23 Botox shots for Spasmodic Dysphonia over nine years. They didn’t give me back my voice. Now I’m cured by Dr. Cooper’s Direct Voice Rehabilitation, all-naturally.

3-Year Update

Dear Dr. Cooper: I am pleased to identify myself as one of your many success stories and case histories. As you know, I use my voice a great deal - as a teacher, a psychologist, a lecturer and so many other professional endeavors. Indeed, I depend upon my voice for almost everything I do, both professionally and personally.

6-Year Update

I have personally worked with Dr. Morton Cooper some six years ago. His techniques are effective immediately. My vocal pedagogy combined with the unique Cooper concepts produce a healthy focused resonance in my voice as well as my students. His books are an integral part of my 'lending library' to all students and friends. Mort is the man!!!

Dear Dr. Cooper:

I would like to begin be expressing my gratitude to you for what you have done to change my life. It has been about a year now since I visited your office for two weeks and since that time I continue to recover from what is known as Spasmodic Dysphonia. I have progressed from barely able to put a full sentence together to my present capability of speaking normally most of the time, even on the phone. I say that because the phone has been the worst for me, at times I could barely squeeze more than a word or two our and had to discontinue my conversation. I am now President of our local Rotary club, and although my voice is not as strong as it should be, I am able to lead our meetings on a weekly basis.

I am extremely grateful to Dr Cooper...after having been to three other doctors without success. Dr. Cooper was able to diagnose my early Spasmodic Dysphonic voice problem and lead me quickly on a path to recovery. Today my voice is stronger than ever and I am in control of my career.
