<View>
<Header value="Listen to the audio:"></Header>

<Header value="Select its topic:"></Header>
<Choices name="label" toName="audio" choice="single-radio" showInline="true">

About the labeling configuration
All labeling configurations must be wrapped in View tags.
You can add a header to provide instructions to the annotator:
<Header value="Listen to the audio:"></Header>
Use the Audio object tag to specify the type and the location of the audio clip. In this case, the audio clip is stored with a url
key in the data:
<Audio name="audio" value="$url"></Audio>
Use the Choices control tag to manage how the classification choices appear to annotators with showInline="true"
and what selection option is used on the interface with choice="single-radio"
. The toName="audio"
option associates the choices with the audio clip.
<Choices name="label" toName="audio" choice="single-radio" showInline="true">
You must use the Choices tag in combination with the Choice to specify the available choices to classify the audio, then close the Choices tag:
<Choice value="Politics"></Choice>
<Choice value="Business"></Choice>
<Choice value="Education"></Choice>
<Choice value="Other"></Choice>
</Choices>
