Other vowel changes, whose relation with the shift is uncertain, are also emerging: moving towards ("rude" and "true" are almost approaching "reed" and "tree", but with rounded lips), and moving beyond ("cone" and "stoke" are almost approaching "cane" and "steak", but with rounded lips). is moving towards (so that, for example, "book" and "could" in the California dialect start to sound, to a GA speaker, more like "buck" and "cud"), is approaching ("mud, glove, what," etc. are sounding like how U.S. southerners pronounce them).
