Introduction to Visual Ouput

Visual output is used to describe or enhance the voice interaction. This ranges from simple cards, Echo Show and Echo Spot Display Templates to displaying a video.

Cards

Cards are used for the most basic cases of visual output. They can be used to display plain text and images or to ask for certain permissions (Account Linking, to-do/shopping lists, etc.) in addition to the speech output.

Simple Card

The simple card can only contain plain text, which is split up into a title and content.
