If one word ends with a vowel and the next word begins with a vowel, do not pause between the words. For a smoother transition between the sounds and to ensure a complete pronunciation of both of the vowels, we insert a short /w/ sound after a front vowel (such as /eɪ/, /i/, and /ai/) and a short /y/ sound after a back vowel (such as /ʊ/ and /oʊ/).
