Have you tried focusing on the second syllable of the word? For me, its words starting with D and with more than 3 syllables like for example "development" . The trick I use is instead of focusing on the first syllable and try to anxiously force out the "de", I focus on the "vel"... as in "de-VELopment". In my head I read it as 2 separate words. Practice at home slowly, it will decrease your anxiety with that word. You will improve.
