there isn't an exact cure, but there are methods; whenever you reach trigger words, for example, if you struggle at the letter "y", then pronounce a different letter before y to make the word easier to pronounce; so "your" will be "d'your" another trick to pronouncing hard words is to separate each syllable; so "reprimand" would be "rep, ri, mand", it will make it much easier to pronounce the full word
