I'm going to assume a few things here, as most people consciously or unconsciously add these filler words/sounds before a stutter and I've seen patterns Things I'm assuming: 1. You don't want to stutter 2. The class doesn't know you stutter 3. You're anticipating your name being called seconds or minutes before it is called 4. You feel an immense pressure to say your name as fast as possible. Before I provide advice, can tell me if I'm wrong or if these things don't apply to you. If you're looking for real advice, let me know and I will tell reply with a thought out plan for you to overcome this.
