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="Select its topic:"></Header>

Use the Labels control tag to allow annotators to segment the audio and classify it at the same time.

<Labels name="label" toName="audio" choice="multiple">
    <Label value="Politics" background="yellow"></Label>
    <Label value="Business" background="red"></Label>
    <Label value="Education" background="blue"></Label>
    <Label value="Other"></Label>
</Labels>

The choice="multiple" argument allows one audio segment to be labeled with multiple topics.

Use the AudioPlus object tag to specify the location of the audio file to classify:

<AudioPlus name="audio" value="$url"></AudioPlus>
