This is something that has interested me for a long time and I have found NO information published. Do any of you have a speech impediment and does it show up in your playing (better or worse high range, tonguing, etc.)? I am not talking about players that open their mouths before shifting their brains in gear (I know how to solve that), I am talking about real handicaps. Players that have had a stroke with slurred speech are also invited to participate! If you have taught people with a similar condition, I am also interested! I have only worked with one tuba player whose face was half paralyzed and got most of the functionality back (he still has a big vibrato, but what he has accomplished, I consider to be a miracle!). Speak in the third person if you do not wish to out yourself!
