Maybe I missed it but are you seeing a speech therapist? If not that would be very helpful in getting your old voice back. They can help you do certain exercises which will strengthen your lips and tongue. I went to one for several visits which greatly helped in my recovery.

I also talked for a living. Unfortunately after this last round of OC my speech is not up to my old companies standards. I took a retirment package last July. No matter what path you end up taking in life, enjoy what you do and where you are. Your job is important but it is not your life.

Best of luck with continued healing.
