The Push-to-Talk screen indicates that the system is actively processing speech commands, which give users a hands-free way to perform a supported set of voice-activated tasks.

Unlike the other main screens in the HMI, the Push-to-Talk screen doesn't display a group of controls. Tapping its tab starts an ASR session for processing voice commands.

When you tap the Push-to-Talk tab, an overlay graphic appears on the top half of the display, indicating that the system is listening for a voice command. When no command is given after a timeout period, the overlay disappears.

For more information on ASR commands, see "Automatic Speech Recognition" in this guide.
