SUEDE User's Guide

SUEDE is a system that helps speech user interface designers quickly create, test, and analyze speech user interface prototypes. SUEDE couples a simple prompt/response card model with the Wizard of Oz technique.

This user's guide leads you through the basics of designing, testing, and analyzing a speech user interface design in SUEDE. There are also exercises to guide you through the creation of an example speech user interface.

There is also a quick reference that lists all of SUEDE's commands.

Terminology

The user is the person who actually uses the interface. This is the person who hears the prompts and responds accordingly.

The Wizard is the person working in the background. He or she is the one who runs SUEDE when testing an interface.

Objects

When designing is SUEDE, you manipulate "cards." There are four different types:

	The start card is included automatically in every SUEDE document. This card is used to tell SUEDE where the speech design begins and also serves as a linking point for the start of the interface. You can move the start card by right-clicking on it and dragging it around. Release the mouse button to put it down.
	An orange prompt card is used to indicate a system prompt, something the computer says to the user. You can add a prompt card to your design by either clicking your right mouse button in the canvas area or by dragging a card from the script bar. (The script bar is covered in detail in section 2.) Prompt cards are moved in the same way as the start card: by right-clicking over it and dragging it around.
	A green response card represents user input, what the user can say to the system. To set up a response card, left-click and drag your work area. A left mouse drag gesture between two prompt cards creates a link while dragging from the background canvas creates a global (user commands that can be spoken at any time, regardless of the prompt). As with prompt cards, response cards can be dragged from the script bar. Note: Response cards don't need to link. A response card with no finish will have a circle around its arrow, as in the diagram. To link such a card, left-drag the arrow over the prompt you'd like to follow the response. The same method is used to reassign a response card's link.
	A blue group card is a set of prompt cards that can all be alternative replies after a specific user response. A flick gesture on the canvas area creates a group and a right mouse drag will allow you to move it.
