I block but I'm silent until I know I can get it out by silently trying to say it numerous times until I feel there is no block. It's not a nice thing when talking in phones, because I tend to get a few "are you there?" every now and then but it's what I'm used to. ​ Grew up doing everything to stutter less. Pronounce words differently, jump around with my head as I'm trying to get words out and this silent thing.
