Thanks! The reason I asked is because people with dysarthria have more trouble reading other people's phrasing than they do talking spontaneously. That's because your subconcious routes around words and timing you aren't good at and picks different words and phrasing. Someone with fairly advanced spasmodic dysarthria can sound pretty normal in conversation but freakish if they try to read a kid's book out loud.
You sound good, you can read quickly and clearly, but sound like you don't feel confident in talking. You might have some sort of subtle voice anomaly people who know you well can detect, but nothing that I would label dysarthria. It reminded me of a video a lady with BFS sent me of her walking. She could bear weight easily on either leg, balance well, and made amazing turns but obviously felt unsteady.
Unless you develop a more pronounced problem strangers can notice, I wouldn't let this stuff worry you. Get to the general doc when you can, but don't let it make you anxious.
