Google Now will check on your car rental reservation and set voice reminders with just your voice5
Also now available from Google is a true voice setting for a reminder. In the past, ask Google Now to remind you to take out the garbage at a certain time, and you would have to tap the screen to confirm your request. That would seem to be a strange thing to have to do when making a reminder via voice.
Google has changed the way a voice reminder is set. Now, ask Google to remind you to take out the garbage at a certain time, and you can confirm the request by saying "yes" or "no". And that's the way a voice reminder should be set.
