Couple things I learned for this sound in therapy: You can still easy onset this sound, you just have to let a little bit of air out and then prolong into the next sound of the word. Hard to explain over text, but just prolong the silent C then get your voice started for the next sound. Another idea is to pseudo stutter it. Like “cuhh cuhh communication” or intentionally focusing and prolonging the second sound of the word, like “cahhhffee” for coffee.
