"Ok Google" is one of the most annoying trigger phrases. I literally have a hard time saying it and have to deliberately slow it down to get it to realize I'm trying to trigger it[1]. This has led to me pretty much abandoning that service..

It's the difference between saying "ok goo-gul" and "ok googl". For whatever reason, the second "g" sound gets dropped or blurred when I say 'google' aloud, so I have to remember to slow down and say it the first way.

"Alexa" and "Siri" are simple, and have no glut of soft sounds stuck in the middle of the word.
