I practiced by reading sermons and recording them. Also reading my bible. I then editied the audios to remove the blocks and stutterers, kept track of all difficult prhases, and practice them. The thing is that there would days were I would read pages of the bible stutter free, and others day it would be bad. Maybe try it when you are alone at home so your parents do not hear you. First you have to acknowledge the difficult words for you, and work from there. Moses was also a stutterer, he denied his call by God at first, but God didnt gave up on him even if he denied Him. God knew what his true intentions were. There is ecopipam and noe105 currently pills on the work. I heard good things about ecopipam
