Optional vector of labels for the NAFC choices.
Audio type (e.g. 'mp3'). Defaults to the provided file extension.

Whether to wait for the audio to finish before displaying the response buttons.

Optional UI component for the admin panel.
Text to display as a prompt for starting the audio. Ordinarily the participant will not see this, but it might appear if the internet connection is poor, or if the participant refreshes the page.
