You can say "Hey Google" now which I find much easier to say. Would be nice if you could rename it though.

Two words seem always worse than one in my point of view

At least two syllables are easier than three. (And "OK Google" is particularly tongue-twisty due to the repeated "oh" sounds.)

It doesn't have repeated vowel sounds unless you pronounce it something like "OK Go-Goal"

It has, in order, one "o", one "u", and one "ə".
