Thank God this block type of stuttering is normal. People around me assumes that i have some other speaking disorder like worse than stuttering. But i am a teenager and still learning and my name start with “i” and as we all know that vowels are hard to pronounce so when someone asks me my name i skip first letter and than pronounce my name with low voice and when they ask again like what? Or what was that,can you repeat. Than i properly pronounce my name i don’t usually stutter while saying same thing for the second time. It works for me
