I just used it and got connected to a local restaurant.
I was on speaker phone, there was a lot background noise, and the voice prompter understood what I was saying. It’s your typical voice recognition setup, just the back end is data collected by Google. The prompter was easy to understand and reacted correctly when I would interrupt it to cut to the chase. It read to me the business I selected and connected me to the restaurant.
Of course I gave the phone to Lily for making reservations. It’s not like I want to speak to a real person…
