Sorry to hear this...have you seen your doctor. Have you been sick with an upper respiratory virus? This happened to me 2 yrs ago and I completely lost it 100% - had to mouth my words and write. it was very frustrating. I had to have my daughter with me to tell the deli guy what kind of lunch meat I wanted lol. Sometimes heartburn can also be the cause from acid splashing up. See a doctor if you haven't already and try not to strain it or force yourself to talk. I hope you feel better.
