Voice-based messaging allows drivers to keep their eyes on the road while communicating. Android Auto's messaging app template uses a single navigation model across all messaging apps. Apps using this template receive and respond to text-based messages only, transforming text such as SMS and email into audio. *** ** * ** *** ## Interaction model [Incoming messages](https://developers.google.com/cars/design/android-auto/apps/incoming-messages) animate downwards from the top of the screen. Drivers can respond to them immediately or access them later, when done driving. [Saved messages](https://developers.google.com/cars/design/android-auto/apps/saved-messages) are available in the Notification Center or on the phone Drivers can access messages through these views: - [Notifications](https://developers.google.com/cars/design/android-auto/product-experience/system-ui/notifications) - [Notification Center](https://developers.google.com/cars/design/android-auto/product-experience/system-ui/notifications#notification_center)  *** ** * ** *** ## Conversational flow Users can play and reply to a message using a single flow.  ### Voice replying to a message This dialogue illustrates the voice commands and sequence used to reply to a text message. To be recognized by Android Auto, commands must be used in one of the patterned sequences | Driver | Google Voice | |---|---| | "Reply!" | "What's the message?" | | "I'll be 10 minutes late. Please start without me. I'll find you when I get there." | "Here is your message to Firstname Lastname: 'I'll be 10 minutes late. Please start without me. I'll find you when I get there.' Do you want to send it?" | | "Yes!" | "Message sent to Firstname Lastname" |
