3. Do you use voice assistants?
   I use them frequently I use them rarely I've never used them before but I would like to try

This part asks how likely it would be for you to use voice-based argument search in different situations and with different motivations. To help you understand the situations and motivations, we added brief example settings.

1. If voice-based argument search were available for you today, how likely would you be to use it...
   Example setting: You are sitting alone at the breakfast table at home and are reminded by the news about an important election in your country next week. You ask your voice assistant to give pro and con arguments for specific parties to help you make a final voting decision.

   	Extremely likely	Very likely	Somewhat likely	Not so likely	Not at all likely	Don't know
   ... alone at home.
   ... to make a voting decision.

5. If voice-based argument search were available for you today, how likely would you be to use it...
   Example setting: You are going into a very busy electronics store to buy a pre-configured PC for yourself.

To help you make a decision on which option is best, you ask your voice assistant for pro and con arguments of Notebooks and Desktop PCs.

12. In your own words, which other functionalities would you need from a (not necessarily voice-based) argument search system? (optional)

13. Just like args.me puts some arguments at the top of the screen, the assistant would need to decide which arguments to speak first. Different criteria can be used to determine these first arguments.

    When you think about the criteria listed below, which of them do you think should be the most important to determine which arguments are spoken first?

    	Most important					Least important	Don't know
    Machine Rating Effect: The first arguments are particularly strong (as determined by an algorithm).
    User Rating Effect: The first arguments are particularly strong (as rated by users).
    Source Reliability Effect: The first arguments are from trustworty sources (as rated by a community).
    Source Coverage Effect: The first arguments cover various sources.
    Aspect Coverage Effect: The first arguments cover various aspects of the topic.
    Recency Effect: The first arguments are up-to-date.
