I can't tell as much either. Most of the time it sounds normal to me. For example I left a message on my wife's cell yesterday. I thought I was speaking clearly, but she said she couldn't understand much of it because I was talking too soft. I think I was in the same boat as you as far as difficulty speaking and forming words. Now that I think I might be close to a dx it makes more sense. My wife picks it up quite often and sometimes my co-workers do too. They tell me I'm talking too softly or I mumbled. I'm not sure if it is a precursor, but it does happen in conjunction to my other symptoms.

I think what often happens is that I am making the same effort to talk, but it comes out softer, just takes more effort to speak some time. Because when my husband says "what?" I am vaguely aware that what I just said was barely audible. Of course my husband is not the best listener in the world. He says himself, his hearing is fine, it's just his listening that is so bad!

hi
My speech gets slurred when I am tired. My friends and family notice it sometimes before I do. The movement of the mouth causes it. If I want to prevent it I have to stop eating hard to chew foods and stop talking. Our speech muscles are just in tune and just like the rest of our body. It gets weak.

My speech also slurs, when I am overtired.
When my speech slurs? I can also count on some minor swallowing problems. (Anything more than a pill, at least for a while.)
My slurring is also interpreted by others - as mere mumbling, as if I just need to speak up, a little.
If I am talking with someone, just conversational? The slurring shows up, anywhere from 10 to 20-minutes, in.
After 20 to 30-minutes? The slurring is bad enough?
Even I - can't tell - what the 'ell - I'm saying!

I always notice when I slur. Things such as "better, pretty, tomato" are harder for me to say because I guess I use my tongue more and that seems to be where I have the most weakness. What I don't notice is how low I can talk sometimes. People often tell me to speak louder. When I am feeling well I speak very, very loud because I guess I'm used to straining so much so people can hear me when I feel weak.

I do notice when I slurr my words. I just have problems getting the words to come out right and sometimes get frustrated. One time it was so bad my friends thought I had a stroke.

Most of the time, other people point it out to me by asking "What?" or "Oh, I thought you said ......"
But the couple of times when it has been really bad I KNEW I couldn't talk. My tongue felt fat and my lips felt weak. I laughed as I tried to get words out and sounded like I had a MAJOR speech impediment. I lost my ability to use some letters like Ss, Fs and half of my Ps. Those incidences coincided with swallowing/breathing issues... so it is something to be cautious about.

I had a first Sunday....I had my grandchildren for the weekend. Then in teaching Sunday school...I drooled twice!! Yikes! How gross. Maybe just because I had used up all my strength with my grandkids? It did upset me...

My speech is slurred more often than not. The more I talk the more slurred it becomes. It is frustrating especially when I am misunderstood.

I notice it..especially when I am tired.

I think part of being a teacher has made me notice it more, too. I also know that my voice will not sound like it used too. It quivers and is sometimes hoarse...

That's right - forgot that.
My voice is always hoarse, now.
But it gets - more hoarse - as I begin to slur my speech.
(Too many symptoms - and not enough brain cells - to remember them all!)

I get hoarse, too, and woke up one day with real difficulties articulating and had to speak in slow motion as it were. b.

Me too, I am told to speak up and stop mumbeling all the time. I don't hear it myself though. When my breathing is bad it's even worse of course. Peaple have complained about my speach almost daily for a year now and I think that is something to add to my list of symptoms I ignored for a long time not knowing anything was wrong.

My first symptom was when I woke one morning and couln't speak. No slurrring just a complete inability to articulate. I thouht I had had a stroke but a visit to the emergency department of the local hospital and referal to a neurologist that afternoon diagnosed MG.

I went on steroids straight away and the voice (and the swallowing and facial muscle control issues which started soon afterwords) have gradually got much less. Now my voice goes only when I excersize my legs. I can talk as much as I likewithout causing a problem but it only takes a short walk down the road to make me really hoarse and quiet and turn my smile into a snarl which is much worst for social interactions than having to whisper. MG reallly is a weird disease.

So to answer your questions Kimber, I can always tell when I am getting hoarse and quiet and my initial speach problem was followed by other symptoms over the next couple of weeks although thanks to the steroids they seem to be getting less

It just depends on which of the almost 100 muscles dealing with speech and voice are weak at the time. It's crazy!
When first diagnosed, quite often my speech was slurred and nasal sounding. I also had some swallowing and breathing issues. I haven't noticed much of that anymore but at times, I do have to up my mestinon when people start asking me to repeat myself and I don't realize I am sounding any differently. I too get hoarse sounding.
