Usually between two consecutive vowels a consonant ~y (glide) sound slightly is said;  e.g., for "chaos" ~kaeyaas or "create" ~kreeyyaet. (in ~truespel)   But this can be silent as well so an apostrophe or double apostrophe is used;  e.g., ~kae'aas ~kree"aet.  In the truespel converter the y-glide version is shown.  See analysis at showing that about 1% of the words on a page have consecutive vowels, thus y-glides.  These 127 words out of 5k s are listed.    For tutorials and converter see .  Truespel is free.
