Joyce posted a note for Charlie that says:
I had similar issues with losing my voice and was very frsutrated since i could only whisper for about 4.5 weeks. It then became croaky. It took about 6 weeks before it was back to normal. When I was in the hospital, an ENT came in and looked at my vocal chords with a scope and said the chords were not paralyzed but they weren't moving like they should and that there is sometimes damage/swelling during the intubation. My surgeon said my voice loss was the worst he'd ever seen. I hope Charlie's voice returns soon because I understand how frustrating it is and how difficult it makes for communication.
