Its is almost almost non existent when i avoid my feared words , no one would know. But if i were to challenge myself and say my idea without changing words , there can be pretty severe blocks ( silent pauses ) , lets say if i were to talk on the phone , no one would be able to tell that i have a stammer in traditional sense as i dont have repetitions or prolongations ( they sometimes occur when i try to push through a block ), they just assume that i am having trouble finding words to say although im pretty sure what words i wanna say.im just struggling to let the words out of my larynx
