Waze forum

Ah, thanks for this thread! I struggled with Siri and Waze for the past year finally landing on "open w-a-z-e" but since the iOS 7 update I've been having limited luck with that even. I finally decided to Google it and landed here. I tried a couple of the suggestions mentioned above which didn't seem to work, but somehow I finally got Siri to pronounce the name back to me and it came out like "woz" or "was". So now when I say "open woz" it has worked for me every time! Lifesaver when trying to do everything by voice while driving!

you can try the following:

I use "speak to it" assistant on android (i think there is an Iphone version too)
and when I say
open wa
it opens waze
wa being pronounced as "wah"

You can also spell the name to Siri and it will open the app.

"Siri, Open W-A-Z-E"
