Hello @jba, I can certainly understand your frustration with your speech problems. Not being able to use your voice effectively is very disappointing, especially given that you are a singer.

I have a paralyzed vocal cord as well. The cause may be Parkinson's but some specialists think it is "idiopathic" or of an unknown cause. Has vocal cord surgery a possibility for you? It was suggested for me. I had an implant placed in the paralyzed cord and it helped my voice quality as well as swallowing problems.

Do you also have problems swallowing?
