I also have problems with my voice. I speak quite quietly now but it sounds loud in my head. Close friends ask me to repeat certain things occasionally.
I slur my words almost all the time but it was only occasionally two years ago. I speak in clipped tones - like a drunk!
I feel as though I'm being strangled. I seem to be holding my breath but that part of me is functionning fine. I seem to click inside, making a noise.
I choked at every meal for about 4 years. Food wasn't stuck but something touching the back of my throat would cause spasms.That has stopped.
I saw a speech therapist yesterday for the first time. It was only an assessment. I've booked in for a proper session soon so will let you know. She seemed of the opinion that physical tiredness had alot to do with it. She also wants me to have a camera put down my throat to see what happens when I spasm.
