I do the same thing as u/Egorte, and it helps me sometimes The other thing that has helped me similar to this is slightly changing the sound of the letter that gives me trouble, to a similar sound. I don't speak dutch, but I assume the "dr" sound is similar to that of English. Also a sound that gives me problems at times. Sometimes, I'll pronounce the "d" like "dge" (like in ledge or bridge, similar sound to the X in Xavi). Kinda like tossing a "zh" in the word. Makes it easier for me to say the word, by being able to stretch into the word. So you'd say it like D*zh*rie
