Speed limits not displayed in AUI

By default, AUI displays speed limits on the cluster display and not the main display.

To override this setting and display speed limits in the main display:

providing-feedback
  • Select Developer settings from the Settings menu.
  • Scroll down to Enable Speed Limit and enable it.
  • Scroll down to Home Screen Adaptiveness and disable it.

After each of those has been toggled correctly, the app requires a restart. Restart the app and the speed limits should appear on the screen.

Changing voice end-detection

End-detection refers to the time between the user concluding their feedback, and the Assistant stops listening. Since users speak at different speeds, we added a feature to allow the user to set the end-detection time to mitigate instances of the Assistant cutting off a user while they are giving feedback. By default, this is set to 2.5 seconds.

To increase the end-detection time:

  • Click the gear (⚙️) icon to open the Settings menu of the Feedback Assistant.
providing-feedback
  • Enable Longer end detection on voice recognition.
  • Click Save.
